The Engineer ,will, within ten (10) days after receipt of each partial payment estimate, either indicate in writing approval of payment, and present the partial payment estimate to the Owner, or return the partial payment estimate to the Contractor indi~ting in writing the reasons for refusing to approve payment. In the latter case, the Contractor may make the necessary couc.Ctions and resubmit the partial payment estimate. The Owner will, within ten (10) days of presentation of an approved partial payment estimate, pay the Contractor a progress payment on the basis of the approved partial payment estimate less the retainage. The retainage shall be an amount equal to 10% of said estimate until 50 % of the work has been completed. At 50 % completion, further partial payments shall be made in full to the Contractor and no additional amounts may be retained unless the Engineer certifies that the job is not proceeding satisfactorily, but amounts previously .l~Wned shall not be paid to the Contractor. At 50% completion or any time thereafter when the prob.lcSS of the work is not satisfactory, additional amounts may be retained but in no event shall the total retain age be more than 10% of the value of the work completed. Upon substantial completion of the work, any amount retained may be paid to the Contractor. When the work has been substantially completed except for work which cannot be completed because of weather conditions, lack of materials, or other reasons which in the judgement of the Owner are valid reasons for non-completion, the Owner may make additional payments, retaining at all times an amount sufficient to cover the estimated cost of the work still to be completed. 19.1.1 The Engineer may disapprove or, on account of subsequently discovered evidence, nullify the whole or part of the approved partial payment estimate to such extent as may be necessary to protect the Owner from loss, on account of: (a) Defective work not remedied. (b) Claims filed or reasonable evidence indicating probable filing of claims. (c) Failure of Contractor to make payment properly to subcontracts or for material or labor. (d) A reasonable doubt that the work can be completed for the balance then unpaid. (e) Damage to another Contractor. (t) Performance of work in violation of the terms of the Contract Documents. 19.1.2 Where work on unit price items is substantially complete but lack clean-up and/or corrections ordered by the Engin'^-.l, amounts shall be deducted from unit prices in partial payment estimates to amply cover such clean-up and corrections. 19. 1.3 When the grounds for withholding or reducing partial payment defmed in 19.1.1 and 19.1.2 are corrected, payment shall be made for the amounts withheld because of them. 19.2 The request for payment may also include an allowance for the cost of such major materials and equipment which are suitably stored either at or near the site. 19.3 Prior to substantial completion, the Owner, with the approval of the Engineer and with the concurrence of the Contractor, may use any completed or substantially completed portions of the work. Such use shall not constitute an acceptance of such portions of the work. JANUARY. 1993 GC-12 19.4 The Owner shall have the right to enter the premises for the purpose of doing w~rk not covered by the Contract Documents. This provision shall not be con.)~ ~ed as relieving the Contractor of the sole responsibility for the care and protection of the work, or the restoration of any damaged work except such as may be caused by agents or employees of the Owner. 19.5 Upon completion and acceptance of the work, the Engineer shall issue a certificate attached to the final. payment request that the work has been accepted under the conditions of the Contract Documents. The entire balance found to be due the Contractor, including the retained percentages, but except such sums as may be lawfully retained by the Owner, shall be paid to the Contractor within thirty (30) days of completion and acceptance of the work. 19.6 The Contractor will indemnify and save the Owner or the Owner's agents harmless from all claims growing out of the lawful demand of subcontractors, laborers, workers, mechanics, materialmen, and furnishers or machinery and parts thereof, equipment, tools and all supplies incurred in the furtherance of the perfonnance of the work. The Contractor shall, at the Owner's request, furnish satisfactory evidence that all obligations of the nature designated above have been paid, discharged or waived. If the Contractor fails to do so the Owner may, after having notified the Contractor, either pay unpaid bills or withhold from the Contractor's unpaid compensation a sum of money deemed reasonably sufficient to pay any and all such lawful claims until satisfactory evidence is furnished that all liabilities have been fully discharged whereupon payment to the Contractor shall be resumed in accordance with the terms of the Contract Documents, but in no event shall the provisions of this sentence be construed to impose any obligations upon the Owner to either the Contractor, the Contractor's surety, or any third party. In paying any unpaid bills of the Contractor, any payment so made by the Owner shall be considered as a payment made under the Contract Documents by the Owner to the Contractor and the owner shall not be liable to the Contractor for any such payments made in good faith. 19.7 If the Owner fails to make payment thirty (30) days after approval by the Engineer, in addition to other remedies available to the Contractor, there shall be added to each such payment interest at the maximum legal rate commencing on the first day after said payment is due and continuing until the payment is received by the Contractor. 20. ACCEt' lANCE OF J11NAL PAYMENT AS RELEASE 20.1 The acceptance by the Contractor of final payment shall be and shall operate as a release to the Owner of all claims and all liability to the Contractor other than claims in stated amounts as may be specifically excepted by the Contractor for all things done or furnished in connection with this work and for every act and neglect of the Owner and others relating to or arising out of this work.

Bales, silt fence or other erosion control measures acceptable to the Engineer shall be used to prevent materials from washing into drainage ways or storm sewers. There shall be an inspection of the sanitary sewer, storm sewer and water main utilities prior to the start of construction. The Contractor shall notify the Engineer 24 hours in advance to aid in accomplishing this inspection. All deficiencies in these existing systems prior to beginning construction must be immediately brought to the attention of the Engineer. During construction, the Contractor shall maintain the streets and control dust as directed by the Engineer. Dust control shall be provided in the same manner to stockpiles of topsoil, dirt, or other materials throughout the period of construction. Payment for maintaining streets and controlling dust shall be incidental to this project and no separate payment made unless provided for on the BID. JUNE, 1993 2500-6 B. Work Limits The Owner has obtained p~uuanent and temporary easements for all construction on private property, as shown on the plan sheets. The remaining construction is within the right-of-way of dedicated streets. The Contractor shall limit his operations to the street right-of-way or easement unless he makes a separate arrangement with the landowner for the use of additional land. B .1. Work on Existine Riqht-of- W avs: In the case of construction on a railroad, state or county highway right-of-way, a permit for such construction will be obtained by the Owner. The Contractor shall comply with all requirements specified by the permit with respect to limits, safety precautions, method of construction, etc., and shall furnish to the state or county highway department or the railroad the required supplemental bonds or insurance coverages as stipulated in the permits without additional cost to the Owner. C. Establishing Line and Grade, The primary line and grade will be established by the Engineer. Line and grade stakes will be set parallel to the proposed pipeline at an appropriate offset and interval as will serve the Contractors operations wherever practical; at each change in line or grade; and as needed for pipeline appurtenances and service lines. The Contractor shall arrange his operations to avoid unnecessary interference 'with the establishment of the primary line and grade stakes; and shall render whatever assistance may be required by the Engineer to accomplish the staking. The Contractor shall be responsible for preservation of the primary stakes and shall bear the full cost of any restaking necessitated by his negligence. The Contractor shall be solely responsible for the correct transfer of the primary line and grade from the stakes to all working points and for construction of the work to the prescribed lines and grades. Unless otherwise specified in the Plans, Specifications, and Specific Requirements, all water main shall generally be placed with 7-1/2 feet of cover. However, a greater depth may be required to clear storm and sanitary sewers and sewer services, and no additional compensation shall be provided for such adjustments. In certain locations where water main is in direct conflict with storm or sanitary sewer, the water main shall be constructed under the sewer. Where it is necessary to use vertical bends to avoid sewer mains, no extra compensation will be made for this construction. No deviation shall be made from the required line or grade except with the consent of the Engineer. JUNE, 1993 2500- 7 T In areas of contlict between water mains, house sewers, storm sewers, or sanitary sewers, a separation of at least 18 inches between the water main and the sewer shall be provided. ~en local conditions prevent a vertical separation as described, the following construction shall be used: (1) Sewers passing over or under water mains shall be constructed of materials equal to water main standards of construction for a distance of at least 9 feet on either side of the water main. (2) Water main passing under sewers shall, in addition, be protected by providing: (a) adequate structural support for the sewers to prevent excessive deflection of joints and settling on and breaking of the water mains; and (b) that the length of water pipe be centered at the point of crossing so that the joints will be equidistant and as far as possible from the sewer. Water mains shall be laid at least 10 feet horizontally from any sanitary sewer, storm sewer or sewer manhole, whenever possible. When local conditions prevent a horizontal separation of 10 feet a water main main may be laid closer to a storm or sanitary sewer provided that: (1) the bottom of the water main is at least 18 inches above the top of the sewer; (2) where this vertical separation cannot be obtained, the sewer shall be constructed of materials and with joints that are equivalent to water main standards of construction and shall be pressure tested to assure watenightness prior to backfilling. D. Protection of Surface Structures All surface structures and features located outside the excavation limits for underground installations, together with those within the construction areas which are indicated in the Plans as being saved, shall be properly protected against damage and shall not be disturbed or removed without approval of the Engineer. Within the construction limits, as required, the removal of improvements such as paving, curbing, walks, turf, etc., shall be subject to accc;i-'Lable replacement after completion of underground work, with all expense of removal and replacement being borne by the Contractor unless separate compensation is specifically provided for in the Contract. Obstructions such as street signs, mailboxes, guard posts, culverts, and other items of prefabricated construction may be temporarily removed during construction provided essential service is maintained in a relocated setting as approved by the Engineer and nonessential items are properly stored for the duration of construction. Upon completion of the underground work, all such items shall be replaced in their proper setting by and at the sole expense of the Contractor. JUNE. 1993 2500-8 In the event of damage to any surface improvements, either privately or publicly owned, the COU~Q.ctor will be required to replace or repair the damaged property to the satisfaction of th~ Engineer and by the Contractor at his expense. E. Interference ofUndereround Structures When any underground structure interferes with the planned placement of pipe or appurtenances and required alterations in the work to eliminate the conflict or avoid endangering effects on either the existing or proposed facilities, the Contractor shall immediately notify the Engineer and the Owner of the affected structures. When any existing facilities are endangered by the Contractor's operations, he shall cease his operations at the site and take such precautions as may be necessary to protect the inplace structures until a decision is made as to how the conflict will be resolved. Without specific authorization from the utility owner, no essential utility service shall be disrupted, nor shall any change be made in either the existing structures or the planned installations to overcome the interference. Alterations to existing facilities will be allowed only when that service will not be curtailed unavoidably and then only when the encroachment or relocation will satisfy all applicable regulations and conditions. Wherever alterations are required as a result of unforeseen underground interferences not due to any fault or negligence of the Contractor, the Engineer will issue a written change order covering any additional or extra work involved and specifying the revised basis of payment, if any. Any alterations made strictly for the convenience of the Contractor shall be subject to prior approval and shall be at the Contractor's expense. No extra compensation will be allowed for delays caused by the interference of underground structures unless approved by the Engineer and included in a change order. F. Removal of Surface Imorovements Removal of surface improvements in connection with trench excavation shall be limited to actual needs for installation of the pipeline and appurtenances. Removal operations shall be coordinated effectively with the excavation and installation operations as will cause the least practical disruption of traffic or inconvenience to the public. Removed debris shall not be deposited at locations that will restrict access to fire hydrants, private driveways, or other essential service areas. Removal and final disposal of debris shall be accomplished as a single operation whenever possible and the debris shall be removed from the site before starting the excavating operations. Removal of concrete or bituminous structures shall be by methods producing clean-cut breakage that will preserve the remaining structure without damage. Concrete or bituminous paving shall be removed so when the trench is excavated there will be a six inch wide minimum undisturbed subgrade and aggregate base course lip. Removal equipment shall not be operated in a manner that will cause damage to the remaining or adjoining property. Where not removed to an existing joint, concrete structures shall be sawed along the break lines to a minimum depth of one-third of the structure depth. JUNE. 1993 2500-9 T Any reusable materials or materials for recycling, such as asphalt, concrete, aggregate, sod or topsoil, shall be segregated from other waste materials and be stockpiled so as to maintain suitability and permit proper reuse. G. Excavation and Trench Preoaration Excavating operations shall proceed only so far in advance of pipe laying as will satisfy the needs for construction of work and permit advance verification of unobstructed line and grade as planned. Where interference with existing structures is possible or in any way indicated, and where necessary to establish elevation or direction for connections to inplace structures, the excavating shall be done at those locations in advance of the main operation so actual conditions will be exposed in sufficient time to make adjustments without resorting to extra work or unnecessary delay. All installations shall be accomplished by open trench construction except where boring and jacking or tunnel construction methods shall be employed as specifically required by the Plans or approved by the Engineer. Surface structures must be properly supported and the backfill restored to the satisfaction of the Engineer. The excavation operations shall be conducted to carefully expose all inplace underground structures without damage. Wherever the excavation extends under or approaches close to an existing structure as to endanger it in any way, precautions and protective measures shall be taken as necessary to preserve the structure and provide temporary support. Hand methods of excavating shall be utilized to probe for and expose such critical or hazardous installations as gas pipe and power or telephone cables. G.l Classification and Deoosition of Materials: All materiais encountered in the excavations, "",ith the exception of items classified for payment as structure removals, will be considered as Unclassified Excavation. Unclassified materials shall include muck, rubble. wood debris, boulder stone, masonry or concrete fragments less than one cubic yard in volume, together with other miscellaneous matter that can be removed effectively with power operated excavators. Excavated materials will be classified for reuse as being either Suitable or Unsuitable for backfill or other specified use, subject to selective controls. All suitable materials shall be reserved for backfill to the extent needed, and any surplus remaining shall be utilized for other construction on the project as may be specified or ordered by the Engineer. To the extent practical, granular materials and topsoil shall be segregated from other materials during the excavating and stockpiling operations so as to permit best use of the available materials at the time of backfilling. All excavated materials reserved for backfill or other use on the project shall be stored at locations approved by the Engineer that will cause a minimum of nuisance or inconvenience to public travel, adjacent properties, and other special interests. The material shall not be deposited so close to the edges of the excavations as would create hazardous conditions, nor shall any material be placed so as to block the access to emergency services. All materials considered unsuitable by the Engineer, for any JUNE, 1993 2500-10 use on the project, shall be immediately removed from the project and be disposed of as arranged for by the Contractor. G.2 Excavation Limitations and Reauirements: Trench excavating shall be to a depth that will pc-uuit preparation of the foundatio~ as specified, and installation of the pipeline and appurtenances at the prescribed line and grade except where alterations are specifically authorized. Trench widths shall be sufficient to p~uuit the pipe to be laid and jointed properly and the backfill to be placed and compacted as specified. Extra width shall be provided as necessary to permit convenient placement of sheeting and shoring and to accommodate placement of appurtenances. Excavations shall be extended below the bottom of structure grade as necessary to accommodate any required Granular Bedding material. When unstable foundation materials are encountered at the established grade, additional materials shall be removed as specified or ordered by the Engineer to produce an acceptable foundation. All excavations below grade shall be to a minimum width equal to the outside pipe diameter plus two (2) feet. Trench widths shall allow for at least six inches of clearance on each side of the joint hubs. The maximum allowable width of the trench at the top of pipe level shall be the outside diameter of the pipe plus two feet. The width of the trench at the ground surface shall be held to a minimum to prevent unnecessary destruction of the surface structures while maintaining safe working conditions. The maximum allowable trench width at the level of the top of pipe may be exceeded only by approval of the Engineer, after his consideration of pipe strength and loading relationships. Any alternate proposals made by the Contractor shall be in writing, giving the pertinent soil weight data and proposed pipe strength alternate, and shall be made in a timely manner so as not to delay the project. Approval of alternate pipe designs shall be with the understanding that no extra compensation will be allowed for any increase in material or construction costs. G.3 Sheeting and BracinQ: Excavations,: All excavations shall be sheeted, shored, and braced as will meet all requirements of the applicable safety codes and regulations; comply with any specific requirements of the Contract; and prevent disturbance or settlement of adjacent surfaces, foundations, structures, utilities, and other properties. Any damages to the work under contract or to adjacent structures or property caused by settlement, water or earth pressures, slides, cave-ins, or other causes due to failure or lack of sheeting, shoring, or bracing or through negligence or fault of the Contractor in any manner shall be repaired by the Contractor at his expense and without delay. Where conditions warrant extreme care, the Contractor shall exercise special precautions to protect life and property. This may include the installation of sheet piling of the interlocking type or shall include other safety measures be taken as the Contractor deems necessary. The Contractor shall at all times be responsible for protection of life, property, and the work on the project. JUNE, 1993 2500-11 r-... JUNE. 1993 The Contractor shall assume full responsibility for proper and adequate placement of sheeting, shoring, and bracing, wherever and to such depths that soil stability may dictate the need for support to prevent displacement. Bracing shall be so arranged as to provide ample working space and so as not to place stress or strain on the inplace structures to any extent that may caus~ damage. Sheeting, shoring and bracing materials shall be removed only when and in such manner as will assure adequate protection of the inplace structures and prevent displacement of supported grounds. Sheeting and bracing shall be left in place only as required by the Contract. Otherwise, sheeting and bracing may be removed as the backfilling reaches the level of respective support. Wherever sheeting and bracing is left in place, the upper portions shall be cut and removed to an elevation of three (3) feet or more below the established surface grade or as the Engineer may direct. All costs of furnishing, placing and removing sheeting, shoring and bracing materials, including the value of materials left in place as required by the Contract, shall be included in the prices bid for pipe installation and will not be compensated for separately. When any sheeting, shoring, or bracing materials are left in place by \\TItten order of the Engineer, payment may be made for those materials as an extra work item, including waste material resulting from upper cut-off requirements. G.4 Preoaration and Maintenance of Foundations,: Foundation preparations shall be conducted to produce a stable foundation and provide continuous and uniform pipe bearing between bell holes. Where Class C bedding is specified, the initial excavating or backfilling operations shall produce a sub grade level slightly above finished grade to pennit hand shaping to finished grade by trimming of high spots and without the need for filling of low spots to grade. In excavations made below grade to remove unstable materials, the backfilling to grade shall be made with Granular Foundation material. Placement of the backfill shall be in relatively uniform layers not exceeding eight (8) inches in loose thickness. Each layer of backfill shall be compacted thoroughly, by means of approved mechanical compaction equipment, to produce uniform pipe support throughout the full pipe length and facilitate proper shaping of the pipe bed. \Vhere the foundation soil is found to consist of materials that the Engineer considers to be so unstable as to preclude removal and replacement to a reasonable depth to achieve solid support, a suitable foundation shall be constructed as the Engineer directs in the absence of special requirements therefore in the Contract. The Contractor shall be required to furnish and drive piling and construct concrete or timber bearing supports or other work as provided for in an extra work order. Care shall be taken during final subgrade shaping to prevent over-excavation. Should any low spots develop, they shall only be filled with Granular Foundation material, which shall be compacted thoroughly, without additional compensation provided to the Contractor. The finished subgrade shall be maintained free of water and shall not be disturbed during pipe lowering operations except as necessary to remove pipe 2500-12 slings. The discharge of trench dewatering pumps shall be directed to natural drainage channels or storm water drains in a manner which does not cause damage to private or public property. Any debris left by dewatering operations shall be cleaned up immediately by the Contractor. Draining trench water into sanitary sewers or combined sewers will not be pennitte~. The Contractor shall install and operate a dewatering system of wells or points to maintain pipe trenches free of water wherever necessary or as directed by the Engineer to meet the intent of these specifications. Unless otherwise specified in the Plans, Specifications, or Specific Requirements, such work shall be considered incidental with no additional compensation provided therefore. All costs of excavating below grade and placing foundation or bedding aggregates as required shall be included in the bid prices for pipe items to the extent that the need for such work is indicated in the Contract provisions and the BID does not provide for payment therefore under separate BID items. If examination by the Engineer reveals the need for placement of foundation aggregates was caused by the Contractor's manipulation of the soils in the presence of excessive moisture or lack of proper dewatering, the cost of the corrective measures shall be borne by the Contractor. H. Installation ofPioe and Fittings, Inspection, handling, and all aspects of the installation of pipe, services, and appurtenances shall be in accordance with the manufacturer's recommendations, and as supplemented as follows: H.l Insoection and Handline: Proper and adequate implements, tools, and facilities shall be provided and used by the Contractor for the safe and convenient prosecution of the work. Unloading, distribution, and storage of pipe and appurtenant materials on the job site shall be at a location approved by the Engineer. All materials shall be handled carefully, as will prevent damage to protective coatings, linings, and joint fittings; preclude contamination of interior areas; and to avoid jolting contact, dropping or dumping. Before being lowered into laying position, the Contractor shall make a thorough visual inspection of each pipe section and appurtenant units to detect damage or unsound conditions that may need corrective action or be cause for rejection. Inspection procedure shall be as approved by the Engineer, with special methods being required as deemed necessary to check out suspected defects more definitely. The Contractor shall infvuu the Engineer of any defects discovered and the Engineer will prescribe the required corrective action or order rejection. Immediately before placement, the joint surfaces of each pipe section and fitting shall be inspected for the presence of foreign matter, coating blisters, rough edges or JUNE, 1993 2500-13 r--- JUNE. 1993 projections, and any imperfections so detected shall be corrected by cleanmg, trimming, or repairs as needed. H.2 Pine Lavinsz O!'erations: Trench excavation and bedding preparations shall proceed ahead of pipe placement as will pe~t proper laying and joining of the units at the prescribed grade and aligmnent without unnecessary deviation or hindrance. All foreign matter or dirt shall be removed from the inside of the pipe and fittings before they are lowered into position in the trench and they shall be kept clean by approved means during and after laying. The sewer materials shall be carefully lowered into laying position by the use of suitable restraining devices. Under no circumstances shall the pipe be dropped into the trench. At the time of pipe placement, the bedding conditions shall be such as to provide unifonn and continuous support for the pipe between bell holes. Bell holes shall be excavated as necessary to make the joint connections, but they shall be no larger than would be adequate to support the pipe throughout its length. No pipe material shall be laid in water nor when the trench or bedding conditions are otherwise unsuitable or improper. When placement or handling precautions prove inadequate, in the Engineer's opinion, the Contractor shall provide and install suitable plugs or caps effectively closing the open ends of each pipe section before it is lowered into laying position, and they shall remain so covered until removal is necessary for connection of an adjoining unit. Unless otherwise permitted by the Engineer, bell and spigot pipe shall be laid with the bell ends facing upgrade and the laying shall start on the downgrade end and proceed upgrade. As each length of bell and spigot pipe is placed in laying positio~ the spigot end shall be centered in the bell and the pipe forced home and brought to correct line and grade. The pipe shall be secured in place with approved backfill material, which shall be thoroughly compacted by tamping around the pipe and out to the trench wall. Connection of pipe to existing lines or previously constructed manholes or catch basins shall be accomplished as shown in the Plans or as otherwise approved by the Engineer. Entrance of foreign matter into pipeline openings shall be prevented at all times to the extent that suitable plugs or covering can be kept in place over the openings without interfering with the installation operations. Unless otherwise noted in the Specific Requirements, pipe bedding shall be Class C as shown on the detail plates. Concrete pipe ties shall be installed on a minimum of the last 3 joints and at aprons unless indicated otherwise. 2500-14 Corrugated steel pipe shall be installed with the circumferential joints with the, outside laps pointing UP& "de and with the longitudinal joints on the sides. I. Manhole and Catchbasin Structures Manholes, catchbasins and other special access structures shall be constructed at designated locations as required by the plans and in accordance with the detail plates. Unless otherwise specified or approvecL manholes and catchbasins shall be constructed of precast concrete sections, integral base and barrel, riser sections, eccentric cone or flat top, and adjusting rings. All units shall be properly fitted and sealed to form a completely watertight structure. Barrel and cone height shall be such as to permit placement of at least two and not more than six standard two- inch precast concrete adjusting rings immediately below the casting assembly set in a full mortar bed, 1/4" to 1/2" thick without the use of shims or blocking. Rings shall be plastered on the exterior to form a watertight seal. When placing the precast base, the bedding shall be solid and compacted to the grade necessary prior to setting the base. Manipulation of the base to achieve the proper grade will not be allowed. If the base is low and needs fill to level it or is high and material must be removed, the base shall be removed, bedding corrected, and the base reset to proper grade. Unless otherwise specified or approved, manholes shall have an inside barrel diameter of 48 inches minimum, and the inside diameter at the top of the cone section and of adjusting rings shall be 27 inches; catchbasins shall be 27 inches in diameter. Catchbasin grate elevations shall be adjusted as necessary to maintain the required dip below normal gutter grade. Concrete cast-in-place bases shall be poured on undisturbed or firmly compacted foundation material which shall be trimmed to proper elevation. The bottom riser sections shall be set in fresh concrete or mortar and all other riser section joints of the tongue and groove design shall be sealed with rubber O-ring gaskets. Wherever special designs so require or permit, the structure may be constructed with solid concrete sewer brick or block units or cast-in- place concrete. Any combination of cast-in-place concrete and concrete brick or solid concrete block mortar construction will be allowed and may be required where it is impossible to complete the construction with standard precast manhole sections. All annular wall space surrounding the inplace pipes shall be completely filled with mortar or concrete, and the inside bottom of each structure shall be shaped with concrete to provide free flow through invert channels. Invert channels shall extend to the pipe centerline and side floors slope upward to the structure walls. Steps shall be spaced 16" on center, the top step shall be no greater than 30" from the top of the casting, the bottom step shall be no greater than 16" from the structure floor, offsetting of the bottom step from the step row may be necessary due to the outlet pipe location.

J. Jack-Bore Reinforced Concrete Pi!>e The Contractor shall jack-bore reinforced concrete pipe (RCP) in place as specified and as located on the plans. In native granular soils, a 1-1/2" pipe shall be forced along the top of the RCP. The end of this 1-1/2" pipe shall be 18" back from the lead edge of the jacking pipe. Bentonite grout under pressure shall be forced through this pipe at all times during the jacking operation to fill any voids that might develop above the pipe. The Contractor shall be responsible for obtaining and for paying any special permit fees or bonds, which may be required to accomplish the work. K. Placement of Insulation Rigid insulation board shall be placed within the pipe encasement zone, six (6) inches above the pipe. Prior to placement of the insulation, encasement material shall be compacted until there is no further visual evidence of increased consolidation or the density of the compacted layer conforms to the density requirements specified in the Specific Requirements, then leveled and lightly scarified to a depth of 1/2 inch. Encasement zone material placed below the insulation shall be free of rock or stone fragments measuring 1-1/2 inches or greater. Insulation boards shall be placed on the scarified material with the long dimension parallel to the centerline of the pipe. Boards placed in a single layer shall be overlapped at least 6 inches on all sides to eliminate continuous joints for the full depth of the insulation. If two or more layers of insulation boards are used, each layer shall be placed to cover the joints of the layer immediately below with an overlap of at least 6 inches. The Contractor shall exercise precaution to insure that all joints between boards are tight during placement and backfilling with only extruded ends placed end to end or edge to edge. Broken or damaged material shall be removed and replaced. The first layer of material placed over the insulation shall be 6 inches in depth, free of rock or stone fragments measuring 1-1/2 inches or greater. The material shall be placed in such a manner that construction equipment does not operate directly on the insulation and shall be compacted with equipment which exerts a contact pressure of less than 80 psi. The first layer shall be compacted until there is no further visual evidence of increased consolidation or the density of the compacted layer conforms to the density requirements specified. L. Pioeline Backfilline: Ooerations All pipeline excavations shall be backfilled to restore pre-existing conditions as the minimum requirements, and fulfill all supplementary requirements indicated in the Plans and Specifications. The backfilling operations shall be started as soon as conditions will permit JUNE. 1993 2500-16 on each section of pipeline, so as to provide continuity in subsequent operations an~ restore normal public service as soon as practicable on a section-by-section basis. All operations shall be pursued diligently, with proper and adequate equipment, as will assure acceptable results. Backfilling shall be accomplished with the use of Suitable Materials selected from the excavated materials to the extent available and practical. Suitable Material shall be defined as a mineral soil reasonably free of foreign materials (rubbish, debris, etc.), frozen clumps, organic matter, stone, rock, concrete, or bituminous chunks, larger than 4", and other unsuitable materials that may damage the pipe installation or prevent thorough compaction, taking into consideration particular needs of different backfill zones. Unsuitable material shall only be utilized where and to the extent there will be no detrimental effects and with the approval of the Engineer. Back:fill materials shall be carefully placed in relatively uniform depth layers spread over the full width and length of the trench section to provide simultaneous support on both sides of the pipeline. Each layer shall be compacted effectively, by approved mechanical methods before placing material for a succeeding layer thereon. Within the pipe bedding zone compaction shall be in a minimum of three lifts: invert to spring line, spring line to top of pipe, and top of pipe to 1.0 foot over top of pipe. Maximum thickness of any lift shall be eight (8) inches compacted thickness. Compaction requirements are: 95% Standard Proctor maximum dry density from the pipe zone to within 3 feet of the ground surface, and 100% Standard Proctor maximum dry density in the final 3 feet. All surplus or waste materials remaining after completion of the backfilling operations shall be disposed of in an acceptable manner after completing the backfill work. Disposal at any location within the project limits shall be as specified. or as approved in writing by the Engineer; otherwise, disposal shall be accomplished outside the project limits at the Contractor's own dump site. M. Rio-Rao Rip-rap shall be installed in accordance with MnDOT 2511. Immediately prior to placing the grout for grouted rip-rap, the stones shall be thoroughly wetted with water. No grout shall be poured over stones that have a dry surface. The spaces between stones, throughout the entire thickness of the rip- rap, shall be filled with grout. The surface of the grouted rip-rap shall be finished by sweeping with a stiffbroom. N. Restoration of Surface Imorovements Wherever any surface improvements such as pavement, curbing, pedestrian walks, fencing or turfhave been removed, damaged or otherwise disturbed by the Contractor's operations, they shall be repaired or replaced in kind and structure to the pre-existing condition or better. JUNE. 1993 2500-17 T Each item of restoration work shall be done as soon as practical after completion of installation and backfilling operations on each section of pipeline. In the absence of specific payment provisions, as separate BID items, the restoration work shall be compensated as part of the work requir:ed under those BID items which necessitated the destruction and replacement of repair, and there will be no separate payment thereof If separate pay items are provided for restoration work, only that portion of the repair or reconstruction which was necessitated by the Contract work will be measured for payment Any improvements removed or damaged unnecessarily shall be replaced or repaired by the Contractor at his expense. A proper foundation shall be prepared before reconstructing concrete or bituminous improvements. Unless otherwise directed, granular material shall be placed to a depth of at least four (4) inches under all concrete and bituminous items. No direct compensation will be made for furnishing and placing this material even though such course was not part of the original construction. Existing concrete and bituminous surfaces at the trench wall shall be sawed or cut with a cutting wheel to fonn a neat edge in a straight line before surfaces are to be restored. Sawing or cutting may be accomplished as a part of the removal or prior to restoration at the option of the Contractor. However, all surface edges shall be inspected prior to restoration. O. Maintenance and Final Cleanuo All subgrade surfaces shall be maintained acceptably until the start of surface construction or restoration work. Additional materials shall be provided and placed as needed to compensate for trench settlement and to serve until completion of the final surface improvements. Final disposal of debris, waste materials, and other remains or consequence of construction, shall be accomplished prior to final acceptance of all work. Final acceptance of each BID item can only be made when the cleanup associated with each item is completed. The Engineer may withhold partial payment until such work is satisfactorily pursued or he may deduct the estimated cost of its performance from the partial estimate value. 2500.4 ~THOD OF ~ASUREMENT A.

The Contractor shall keep the portions of the project being used by public traffic, whether it be through or local traffic, in such condition that the traffic will be adequately accommodated at all times. The Contractor shall provide and maintain temporary approaches, crossings, and intersections with trails, roads, ~L.c.ets, businesses, parking lots, residences, garages, farms, and other abutting property in acceptable condition. The Contractor shall maintain essential services during the course of the project. Essential services shall include emergency vehicles, buses, mail delivery, garbage collection, drainage and public utility services. The Contractor shall coordinate his work with all appropriate agencies and utility companies during construction. During construction it shall be the Contractor's responsibility to see that all existing drainage structures, ditches, gutters and utilities in the working area are kept clean. Gutters shall be cleaned and free of dirt and other materials at the end of each working day to ensure proper drainage. Bales, silt fence or other erosion control measures acceptable to the Engineer shall be used to prevent materials from washing into drainage ways or storm sewers. There shall be an inspection of the sanitary sewer, storm sewer and watermain utilities prior to the start of construction. The Contractor shall notify the Engineer 24 hours in advance to aid in accomplishing this inspection. All deficiencies in these existing systems prior to beginning construction must be immediately brought to the attention of the Engineer. During construction, the Contractor shall maintain the streets and control dust as directed by the Engineer. Dust control shall be provided in the same manner to stockpiles of topsoil, dirt, or other materials throughout the period of construction. Payment for maintaining streets and controlling dust shall be incidental to this project and no separate payment made unless provided for on the BID. B. Wnrk T Units The Owner has obtained permanent and temporary easements for all construction on private property, as shown on the plan sheets. The remaining construction is within the right-of-way of dedicated streets.

The primary line and grade will be established by the Engineer. Line and sUlde stakes will be set parallel to the proposed pipeline at an appropriate offset and interval as will serve the Contractor's operations wherever practical; at each change in line or bJ.c1de; and as needed for pipeline appurtenances and service lines. The Contractor shall arrange his operations to avoid unnecessary interference with the establishment of the primary line and grade stakes; and shall render whatever assistance may be required by the Engineer to accomplish the staking. The Contractor shall be responsible for preservation of the primary stakes and shall bear the full cost of any restaking necessitated by his negligence. The Contractor shall be solely responsible for the correct transfer of the primary line and grade from the stakes to all working points and for construction of the work to the prescribed lines and grades. Unless otherwise specified in the Plans, Specifications, and Specific Requirements, all watermain shall generally be placed with 7-1/2 feet of cover. However, a greater depth may be required to clear storm and sanitary sewers and sewer services, and no additional compensation shall be provided for such adjustments. In certain locations where watennain is in direct conflict with storm or sanitary sewer, the watermain shall be constructed under the sewer. Where it is necessary to use vertical bends to avoid sewer mains, no extra compensation will be made for this construction with the exception of payment for fittings used. No deviation shall be made from the required line or grade except with the consent of the Engineer. In areas of conflict between watermains, house sewers, storm sewers, or sanitary sewers, a separation of at least 18 inches between the watermain and the sewer shall be provided. When local conditions prevent a vertical separation as described, the following construction shall be used: (1) Sewers passing over or under watermains shall be constructed of material equal to watennain standards of construction for a distance of at least 9 feet on either side of the watermain. (2) Watermain passing under sewers shall, m addition, be protected by providing: JANUARY. 1993 3400-9 (a) adequate structural support for the sewers to prevent excessive deflection of joints and settling on and breaking of the watermains; and (b) that the length of water 'pipe be centered at the point of crossing so that the joints will be equidistant and as far as possible from the sewer. Watermains shall be laid at least 10 feet horizontally from any sanitary sewer, storm sewer or sewer manhole, whenever possible. When local conditions prevent a horizontal separation of 10 feet a watc.uuain may be laid closer to a storm or sanitary sewer provided that: (1) the bottom of the watermain is at least 18 inches above the top of the sewer; (2) where this vertical separation cannot be obtained, the sewer shall be constructed of materials and with joints that are equivalent to watermain standards of construction and shall be pressure tested to assure water- tightness prior to backfilling. D. PTot~tion of Sllrf~~P .c;:tnl~1l1r~~ All surface structures and features located outside the excavation limits for underground installations, together with those within the construction areas which are indicated in the Plans as being saved, shall be properly protected against damage and shall not be disturbed or removed without approval of the Engineer. Within the construction limits, as required, the removal of improvements such as paving, curbing, walks, turf, etc., shall be subject to acceptable replacement after completion of underground work, with all expense of removal and replacement being borne by the Contractor unless separate compensation is specifically provided for in the Contract. Obstructions such as street signs, mailboxes, guard posts, culverts, and other items of prefabricated construction may be temporarily removed during construction provided essential service is maintained in a relocated setting as approved by the Engineer and nonessential items are properly stored for the duration of construction. Upon completion of the underground work, all such items shall be replaced in their proper setting by and at the sole expense of the Contractor. In the event of damage to any surface improvements, either privately or publicly owned, the Contractor will be required to ~c.jJlace or ~c.yair the damaged property to the satisfaction of the Engineer and by the Contractor at his expense. JANUARY, 1993 3400-10 E. In1eJ:fPTP.n~p. of TTnrlp.T'fTnnnrl ~tnl~hlTP.~ When any underground structure interferes with the planned placement of pipe or appurtenances and requires alterations in the work to eliminate the conflict or avoid endangering effects on either the existing or proposed facilities, the Contractor shall immediately notify the Engineer and the Owner of the affected structures. When any existing facilities are endangered by the Contractor's operations, he shall cease his operations at the site and take such precautions as may be necessary to protect the inplace structures until a decision is made as to how the conflict will be resolved. Without specific authorization from the utility owner, no essential utility service shall be disrupted, nor shall any change be made in either the existing structures or the planned installations to overcome the interfc;J.\:'uce. Alterations to existing facilities will be allowed only when that service will not be curtailed unavoidably and then only when the encroachment or relocation will satisfy all applicable regulations and conditions. Wherever alterations are required as a result of unforeseen underground interferences not due to any fault or negligence of the Contractor, the Engineer will issue a written change order covering any additional or extra work involved and specifying the revised basis of payment, if any. Any alterations made strictly for the convenience of the Contractor shall be subject to prior approval and shall be at the Contractor's expense. No extra compensation will be allowed for delays caused by the interference of underground structures unless approved by the Engineer and included in a change order. F. Rf"mnv~l nf Sl1rf~rp. TW!'TnVpmp.nts Removal of surface improvements in connection with trench excavation shall be limited to actual needs for installation of the pipeline and appurtenances. Removal operations shall be coordinated effectively with the excavation and installation operations as will cause the least practical disruption of traffic or inconvenience to the public. Removed debris shall not be deposited at locations that will restrict access to fire hydrants, private driveways, or other essential service areas. Removal and final disposal of debris shall be accomplished as a single operation wherever possible and the debris shall be removed from the site before starting the excavating operations. Removal of concrete or bituminous structures shall be by methods producing clean-cut breakage that will preserve the remaining structure without damage. Concrete or bituminous paving shall be removed so when the trench is excavated there will be a six inch wide minimum undisturbed sub grade and aggregate base course lip. Removal equipment shall not be operated in a manner that will cause damage to the remaining or adjoining property. Where not removed to an existing joint, concrete structures shall be sawed along the break lines to a minimum depth of one-third of the structure depth. JANUARY. 1993 3400-11 Any reusable materials or materials for recycling, such as asphalt, concrete, aggregate, sod or topsoil, shall be segregated from other waste materials and be stockpiled. so as to maintain suitability and permit proper reuse. G. Fx~~v~tinn ~nrl TT~n~h PTep~rntinn Excavating operations shall proceed only so far in advance of pipe laying as will satisfy the needs for construction of work and permit advance verification of unobstructed line and grade as planned. Where interference with existing structures is possible or in any way indicated, and where necessary to establish elevation or direction for connections to inplace structures, the excavating shall be done at those locations in advance of the main operation so actual conditions will be exposed in sufficient time to make adjustments without resorting to extra work or unnecessary delay. All installations shall be accomplished by open trench construction except where boring and jacking or tunnel construction methods shall be employed as specifically required by the Plans or app.lvv'ed by the Engineer. Surface structures must be properly supported and the backfIll restored to the satisfaction of the Engineer. The excavation operations shall be conducted to carefully expose all inplace underground structures without damage. Wherever the excavation extends under or approaches close to an existing structure as to endanger it in any way, precautions and protective measures shall be taken as necessary to preserve the structure and provide temporary support. Hand methods of excavating shall be utilized to probe for and expose such critical or hazardous installations as gas pipe and power or telephone cables. G.1 rl~<\<\lfic~t;on ~nci n;~~o~;t;on nLM~Terials: All materials encountered in the excavations, with the exception of items classified for payment as structure removals, will be considered as Unclassified Excavation. Unclassified materials shall include muck, rubble, wood debris, boulder stone, masonry or concrete fragments less than one (1) cubic yard in volume, together with other miscellaneous matter that can be removed effectively with power operated excavators. Excavated materials will be classified for reuse as being either Suitable or Unsuitable for backfill or other specified use, subject to selective controls. All suitable materials shall be reserved for backfill to the extent needed, and any surplus remaining shall be utilized for other construction on the project as may be specified or ordered by the Engineer. To the extent practical, granular materials and topsoil shall be segregated from other materials during the excavating and stockpiling operations so as to permit best use of the available materials at the time of backfIlling. All excavated materials reserved for backfill or other use on the project shall be stored at locations approved by the Engineer that will cause a minimum of nuisance or inconvenience to public travel, adjacent properties, and other special interests. The material shall not be deposited so close to the edges of the excavations as JANUARY, 1993 3400-12 would create hazardous conditions, nor shall any material be placed so as to block the access to emergency services. All materials considered unsuitable by the Engineer, for any use on the project, shall be immediately removed from the project and be disposed of as arranged for by the Contractor. G.2 F'X~~tinn T imit~tinn~ ~nrl RP.qll;Tp.rnp.nt~: Trench excavating shall be to a depth that will Jk;uuit preparation of the foundation, as specified, and installation of the pipeline and appurtenances at the p~cSCribed line and grade except where alterations are specifically authorized. Trench widths shall be sufficient to permit the pipe to be laid and joined properly and the backftll to be placed and compacted as specified. Extra width shall be provided as necessary to permit convenient placement of sheeting and shoring and to accommodate placement of appurtenances. Excavations shall be extended below the bottom of structure !;lC1de as necessary to accommodate any required Granular Bedding material. When unstable foundation materials are encountered at the established grade, additional materials shall be removed as specified or ordered by the Engineer to produce an acceptable foundation. All excavations below grade shall be to a minimum width equal to the outside pipe diameter plus two (2) feet. Where no other grade controls are indicated or established for the pipeline, the excavating and foundation plC,yarations shall provide a minimum cover over the top of the pipe of 7.5 feet to the proposed final e1C1de as indicated on the plans. Trench widths shall allow for at least six inches of clearance on each side of the joint hubs. The maximum allowable width of the trench at the top of pipe level shall be the outside diameter of the pipe plus two (2) feet, subject to the considerations for alternate pipe loading set forth below. The width of the trench at the ground surface shall be held to a minimum to prevent unnecessary destruction of the surface structures while maintaining sare working conditions. The maximum allowable trench width at the level of the top of pipe may be exceeded only by ClpplVVal of the Engineer, after consideration of pipe strength and loading relationships. Any alternate proposals made by the Contractor shall be in writing, giving the pertinent soil weight data and proposed pipe strength alternate, and shall be made in a timely manner so as not to delay the project. Approval of alternate pipe designs shall be with the understanding that there will be no extra compensation will be allowed for any increase in material or construction costs.

Any damages to the work under contract or to adjacent structures or P1Vyerty caused by settlement, water or earth pressures, slides, cave-ins, or other causes due to failure or lack of sheeting, shoring, or bracing or through negligence JANUARY, 1993 3400-13 or fault of the Contractor in any manner shall be repaired by the Contractor at his expense and without delay. Where conditions warrant extreme care, the Contractor shall exercise special precautions to protect life or property. This may include the installation of sheet piling of the interlocking type or shall include other safety measures be taken as the Contractor deems necessary. The Contractor shall at all times be responsible for protection of life, property, and the work on the project. The Contractor shall assume full responsibility for proper and adequate placement of sheeting, shoring, and bracing, wherever and to such depths that soil stability may dictate the need for support to prevent displacement. Bracing shall be so arranged as to provide ample working space and so as not to place stress or strain on the inplace structures to any extent that may cause damage. Sheeting, shoring and bracing materials shall be removed only when and in such manner as will assure adequate protection of the inplace structures and prevent displacement of supported grounds. Sheeting and bracing shall be left in place only as required by the Contract. Otherwise, sheeting and bracing may be removed as the backfilling reaches the level of respective support. Wherever sheeting and bracing is left in place, the upper portions shall be cut and removed to an elevation of three (3) feet or more below the established surface grade or as the Engineer may direct. All costs of furnishing, placing and removing sheeting, shoring and bracing materials, including the value of materials left in place as required by the Contract, shall be included in the prices bid for pipe installation and will not be compensated for separately. When any sheeting, shoring, or bracing materials are left in place by written order of the Engineer, payment may be made for those materials as an extra work item, including waste material resulting from upper cut-off requirements. G.4 PTf&.p~rnt;nn ~nn M~;ntp.n~n~p. nf Fnllnrl~t;nn~: Foundation preparations shall be conducted to produce a stable foundation and provide continuous and uniform pipe bearing between bell holes. Where Class C bedding is specified, the initial excavating or backfilling operations shall produce a subgrade level slightly above finished grade to permit hand shaping to finished grade by trimming of high spots and without the need for filling of low spots to grade. In excavations made below grade to remove unstable materials, the backfilling to grade shall be made with Granular Foundation material. Placement of the backfill shall be in relatively uniform layers not exceeding eight (8) inches in loose thickness. Each layer of backfill shall be compacted thoroughly, by means of approved mechanical compaction equipment, to produce uniform pipe support throughout the full pipe length and facilitate proper shaping of the pipe bed. JANUARY, 1993 3400-14 Where the foundation soil is found to consist of materials that the Engineer considers to be so unstable as to }I~~lude removal and replacement to a reasonable depth to achieve solid support, a suitable foundation shall be constructed as the Engineer directs in the absence of special requirements therefore in the Contract. The Contractor shall be required to furnish and drive piling and construct concrete or timber bearing supports or other work as provided for in an extra work order. Care shall be taken during final sub grade shaping to prevent any over-excavation. Should any low spots develop, they shall only be filled with Granular Foundation material, which shall be compacted thoroughly, without additional compensation provided to the Contractor. The fInished subgrade shall be maintained free of water and shall not be disturbed during pipe lowering operations except as necessary to remove pipe slings. The discharge of trench dewatering pumps shall be directed to natural drainage channels or storm water drains in a manner which does not cause damage to private or public pJ.v~J.lj. Any debris left by dewatering operations shall be cleaned up immediately by the Contractor. Draining trench water into sanitary sewers or combined sewers will not be pc,uuitted. The Contractor shall install and operate a dewatering system of wells or points to maintain pipe trenches free of water wherever necessary or as directed by the Engineer to meet the intent of these specifications. Unless otherwise specified in the Plans, Specifications, or Specific Requirements, such work shall be considered incidental with no additional compensation provided therefore. All costs of excavating below grade and placing foundation or bedding aggregates as required shall be included in the bid prices for pipe items to the extent that the need for such work is indicated in the Contract provisions and the BID does not provide for payment therefore under separate BID items. If examination by the Engineer reveals the need for placement of foundation agc;J.c;gates was caused by the Contractor I s manipulation of the soils in the presence of excessive moisture or lack of proper dewatering, the cost of the corrective measures shall be borne by the Contractor.

All materials shall be handled carefully, as will prevent damage to JANUARY, 1993 3400-15 T protective coatings, linings, and joint fittings; preclude contamination of interior areas; and to avoid jolting contact, dropping or dumping. Before being lowered into laying position, the Contractor shall make a thorough visual inspection of each pipe section and appurtenant units to detect damage or unsound conditions that may need corrective action or be cause for rejection. Inspection procedure shall be as approved by the Engineer, with special methods being required as he deems necessary to check out suspected defects more definitely. The Contractor shall infvuu the Engineer of any defects discovered and the Engineer will prescribe the required corrective action or order rejection. Immediately before placement, the joint surfaces of each pipe section and fitting shall be inspected for the presence of foreign matter, coating blisters, rough edges or projections, and any imperfections so detected shall be corrected by cleaning, trimming, or repairs as needed. H.2 P;pP. T ~yin~ OpP.~tinn~: TH:~uch excavation and bedding preparations shall proceed ahead of pipe placement as will permit proper laying and joining of the units at the prescribed eJ.4de and alignment without unnecessary deviation or hindrance. All foreign matter or dirt shall be removed from the inside of the pipe and fittings before they are lowered into position in the trench and they shall be kept clean by approved means during and after laying. The sewer materials shall be carefully lowered into laying position by the use of suitable restraining devices. Under no circumstances shall the pipe be dropped into the trench. At the time of pipe placement, the bedding conditions shall be such as to provide uniform and continuous support for the pipe between bell holes. Bell holes shall be excavated as necessary to make the joint connections. but they shall be no larger than would be adequate to support the pipe throughout its length. No pipe material shall be laid in water nor when the trench or bedding conditions are otherwise unsuitable or improper. When placement or handling precautions prove inadequate, in the Engineer's opinion, the Contractor shall provide and install suitable plugs or caps effectively closing the open ends of each pipe section before it is lowered into laying position, and they shall remain so covered until removal is necessary for connection of an adjoining unit. It shall be the sole responsibility of the Contractor for the removal of any debris found in the watermain at any time during the project. As each length of bell and spigot pipe is placed in laying position, the spigot end shall be centered in the bell and the pipe forced home and brought to correct line and grade. The pipe shall be secured in place with approved backfill material, which shall be thoroughly compacted by tamping around the pipe. JANUARY, 1993 3400-16 Connection of pipe to existing or F.l"viously constructed lines shall be accomplished as shown in the Plans or as otherwise approved by the Engineer. At all times when pipe laying is not in pro~cSs, including noon hour and overnight periods, all open ends of the pipe line' shall be closed by wat~J. Gght plugs or other means C1ppJ.vved by the Engineer. If water is present in the trench, the seals shall remain in place until the trench is pumped completely dry.

Strong chlorine solution in the main being treated shall not flow into mains in service. The chlorinated water shall be retained in the main for at least 24 hours, during which time all valves and hydrants shall be operated in order to disinfect the appurtenances. At the end of the 24 hour period the treated water in all portions of the main shall have a residual of not less than 10 mg/L free chlorine. Prefcudl equipment for applying liquid chlorine is a solution feed vacuum operated chlorinator in combination with a booster pump for injecting the chlorine gas solution water into the main to be disinfected. A.3 Fl11~h;nE After the applicable retention period, heavily chlorinated water shall not remain in prolonged contact with the pipe. Chlorinated water shall be flushed from the main until chlorine concentration is no higher than generally in the system for domestic use. The environment to which the chlorinated water is to be discharged shall be inspected. The Contractor shall be responsible to ensure that the receiving area is not damaged by the chlorinated water and shall use a reducing agent for neutralization when necessary. A.4 R~~tp.rioloej~~l Tp.~t~ After final flushing and before the wa~uuain is placed in service, samples of water shall be collected from the end of the main and each branch line for testing for bacteriological quality in accordance with Standard Methods for the Examination of Water and Wastewater, and shall show the absence of coliform organisms. Samples shall be at a rate of one per every 1000 feet of pipe. If water in the pipe does not meet the Minnesota Department of Health requirements, disinfection JANUARY, 1993 3400-30 procedure shall be repeated until meeting the requirements. Acceptance forms from the gOVc,uJng agency shall be furnished to the Engineer. B. Hyrlrn~t~ti~ Tp~ting..nf W~tp.rrn~in~ Each valved section shall be subjected to the pressure test and, if required, the leakage test prescribed hc,J.dn. Testing for the two (2) hour duration shall be with hydrants closed, and valves on hydrant leads and dead end water lines open. Once this portion of the test is completed, the valve on the hydrant leads and dead end water lines shall be closed and hydrants opened. The specified test pressure shall be applied, and the test repeated for 15 minutes to establish the condition of the hydrant lead valves. This shall a.pyly to both the VJ.~ure and leakage test. The Engineer or Owner may require the Contractor to test the first section of pipe installed to demonstrate the Contractors ability to install the pipe in an acceptable manner. When the connection to the existing system is not made with a valve, the Contractor shall test the existing section to the first available valve(s) to determine the condition of the existing system, or the Contractor may make provisions to test his work separately, prior to connection to the existing system, in a manner acceptable to the Engineer. The Contractor shall furnish the pump, pipe connections, gauges, and measuring equipment, and shall perform the testing in the presence of the Engineer. The pressure gauge for the test shall be an Ashcroft Model 1082 with 4-1/2 inch dial face at 1 psi increments. Where ~uuanent air vents are not provided, the Contractor shall provide and install corporation cocks at the high points as needed for release of air as the line is filled wi th water. Where concrete reaction blocking is placed, the watermain shall not be subjected to hydrostatic pressure until at least 5 days have elapsed after the concrete placement, with the exception that this period may be reduced to 2 days where high early strength concrete is used. A t the option of the Engineer, the pressure and leakage tests may be conducted simultaneously. Any defective joints, pipe, fittings, valves, or hydrants, revealed during the testing or before final acceptance of the work shall be satisfactorily corrected and the tests shall be repeated until the specified requirements have been met. B.l EI:r~~l1re Te~t: The section being tested shall be slowly filled with water and the specified test pressure shall be C1.Pplied after all air has been expelled from the pipe. A hydrostatic pressure of 150 pounds per square inch, gauge pressure, measured at the lowest point of elevation, shall be applied by means of a pump connected to the pipe in a satisfactory manner. The gauge pressure shall be checked after a minimum of two (2) hours. A pressure dlv!-' of 1 psi or less will be cause to accept the test section. Several attempts must be made to satisfy the Engineer the vl~sure test will not be successful. If the drop JANUARY, 1993 3400- 31 T is more than 2 psi after these attempts, the Engineer may authorize the leakage test in writing for acceptance. Service Pipe may be tested at the time of the foregoing test, if installed, at the Contractor's option. However, testing of service pipes may be completed as a separate operation from main testing, and if so, the test pressure shall be 100 p.s.i. Service pipe testing, if done separately, shall be done with the corporation stop open. B.2 ~fP' Test: After an unsatisfactory pressure test, and if authorized in writing by the Engineer a leakage test shall be performed on each valved section of watc;uuain to detennine the quantity of water that must be supplied into the section to maintain a test pressure of 150 pounds per square inch, after the air in the pipeline has been expelled and the pipe has been filled with water. The water added shall be recorded to the nearest fluid ounce. After filling the pipe with water and expelling all air in the line, a pressure of 150 psi shall be applied in the same manner as prescribed for the pressure test, and sufficient water shall be measured and supplied into the pipe section to maintain the pressure for a test duration of two (2) hours. Each pipe section tested will be accepted if the leakage does not exceed the quantity determined by the fonnula as shown in the table below, based on an allowable leakage of 11.65 gpd/mile/nominal diameter inch at 150 psi.

C. Electri('~l rand.1.1c.tiv;ty Test The Contractor shall perform a conductivity test within one week after completion of pressure testing of the main on all iron pipe watermains. The Engineer or owner may require the Contractor to test the first section of pipe installed to demonstrate the Contractors ability to install the pipe in an acceptable manner. When the connection to the existing system is not made with a valve, the Contractor shall test the existing section to the fust available valve(s) to determine the condition of the existing system, or the Contractor may make provisions to test his work separately, prior to connection to the existing system, in a manner acceptable to the Engineer. The system (pipeline, valves, fittings and hydrants) shall be tested for electrical continuity and current capacity. The electrical test shall be made after the hydrostatic pressure test and while the line is at nuuual operating 1-ILc,ssure. Backfilling shall have been completed. The line may be tested in sections of convenient length as approved by the Engineer. Direct current of 350 amperes plus or minus 10%, shall be passed through the pipeline for 5 minutes. Current flow through the pipe shall be measured continuously on a suitable ammeter and shall remain steady without interruption or fluctuation throughout the 5-minute test period. Insufficient current or intermittent current or arcing, indicated by large fluctuation of the ammeter needle, shall be evidence of defective contact in the pipeline. The cause shall be isolated and corrected. Thereafter, the section in which the defective test occurred shall be retested as a unit and shall meet the requirements. Sources of D.C. for these tests may be motor generators, arc welding machines, or other approved sources. All such equipment shall be furnished by the Contractor.

The Contractor shall keep the portions of the Project being used by public traffic, whether it be through or local traffic, in such condition that the traffic will be adequately JANUARY, 1993 4000-6 accommodated at all times. The Contractor shall provide and maintain temporary approaches, crossings, and intersections with trails, roads, streets, businesses, parking lots, residences, garages, farms, and other abutting property in acceptable condition. The Contractor shall maintain essential services during the course of the project. Essential services shall include emergency vehicles, buses, mail delivery, garbage, collection, drainage and public utility services. The Contractor shall coordinate his work with all appropriate agencies and utility companies during construction. During construction it shall be the Contractor's responsibility to see that all existing drainage structures, ditches, gutters and utilities in the working area are kept clean. Gutters shall be cleaned and free of dirt and other materials at the end of each working day to ensure proper drainage. Bales, silt fence, or other erosion control measures acceptable to the Engineer shall be used to prevent materials from washing into drainage ways or storm sewers. There shall be an inspection of the existing sanitary sewer, storm sewer and water main utilities prior to the start of construction. The Contractor shall notify the Engineer 24 hours in advance to aid in accomplishing this inspection. All deficiencies in these existing systems prior to beginning construction must be immediately brought to the attention of the Engineer. During construction, the Contractor shall maintain the streets and control dust as directed by the Engineer. Dust control shall be provided in the same manner to stockpiles of topsoil, dirt, or other materials throughout the period of construction. Payment for maintaining streets and controlling dust shall be incidental to this project and no separate payment made unless provided for on the BID. B. Wa,rk Tim; t<:i The Owner has obtained permanent and temporary easements for all construction on private property, as shown on the plan sheets. The remaining construction is within the right-of-way of dedicated streets.

B.l .wn.rk..cn.-FYlstiD~ Rtgh.t::o.f-w~: In the case of construction on a railroad, state or county highway right-of-way, a permit for such construction shall be obtained by the Owner. The Contractor shall comply with all requirements specified by the permit with respect to limits, safety precautions, method of construction, etc., and shall furnish to the state or county highway department or the railroad the required supplemental bonds or insurance coverages as stipulated in the permits without additional cost to the Owner. JANUARY, 1993 4000-7 T C. 'R~t::lhli~hlnp' T ,1ne ::Inn nrad,e - The primary line and grade will be established by the Engineer. Line and grade stakes will be set parallel to the proposed pipeline at an appropriate offset and interval as will serve the Contractor's operations wherever practical; at each change in line or grade; and as needed for pipeline appurtenances and service lines. The Contractor shall arrange his operations to avoid unnecessary interference with the establishment of the primary line and grade stakes; and shall render whatever assistance may be required by the Engineer to accomplish the staking. The Contractor shall be responsible for preservation of the primary stakes and shall bear the full cost of any restaking necessitated by his negligence. The Contractor shall be solely responsible for the correct transfer of the primary line and grade from the stakes to all working points and for construction of the work to the prescribed lines and grades. Unless otherwise specified in the Plans, Specifications, and Specific Requirements, all water main shall generally be placed with 7-1/2 feet of cover. However, a greater depth may be required to clear storm and sanitary sewers and sewer services, and no additional compensation shall be provided for such adjustments. In Cc;1 Lain locations where water main is in direct conflict with storm or sanitary sewer, the water main shall be constructed under the sewer. Where it is necessary to use vertical bends to avoid sewer mains, no extra compensation will be made for this construction. No deviation shall be made from the required line or grade except with the consent of the Engineer. In areas of conflict between water mains. house sewers, storm sewers. or sanitary sewers, a separation of at least 18 inches between the water main and the sewer shall be provided. \Vhen local conditions prevent a vertical separation as described, the following construction shall be used: (1) Sewers passing over or under water mains shall be constructed of materials equal to water main standards of construction for a distance of at least 9 feet on either side of the water main. (2) Water main passing under sewers shall, m addition, be protected by providing: (a) adequate structural support for the sewers to prevent excessive deflection of joints and settling on and breaking of the water mains; and JANUARY, 1993 4000-8 (b) that the length of water pipe be centc,J.c.d at the point of crossing so that the joints will be equidistant and as far as possible from the sewer. Water mains shall be laid at least 10 feet horizontally from any sanitary sewer, storm sewer or sewer manhole, whenever possible. When local conditions prevent a horizontal separation of 10 feet a water main may be laid closer to a storm or sanitary sewer provided that: (1) the bottom of the water main is at least 18 inches above the top of the sewer; (2) where this vertical separation cannot be obtained, the sewer shall be constructed of materials and with joints that are equivalent to water main standards of construction and shall be pressure tested to assure water tightness prior to backfilling. D. ProtectioT\..of ~l1rf::lCP. Stn)ctllre~ All surface structures and features located outside the excavation limits for underground installations, together with those within the construction areas which are indicated in the Plans as being saved, shall be P.l\lyerly protected against damage and shall not be disturbed or removed without approval of the Engineer. Within the construction limits, as required, the removal of improvements such as paving, curbing, walks~ turf, etc., shall be subject to acceptable replacement after completion of underground work, with all expense of removal and replacement being borne by the Contractor unless separate compensation is specifically provided for in the Contract. Obstructions such as street signs, mailboxes, guard posts, culverts, and other items of prefabricated construction may be temporarily removed during construction provided essential service is maintained in a relocated setting as approved by the Engineer and nonessential items are properly stored for the duration of construction. Upon completion of the underground work, all such items shall be replaced in their proper setting by and at the sole expense of the Contractor. In the event of damage to any surface improvements, either privately or publicly owned, the Contractor will be required to replace or repair the damaged property to the satisfaction of the Engineer and by the Contractor at his expense. E. Tnterferen~p. of TTnnp.reronnn Stn)(~tllre~ When any underground structure interferes with the planned placement of pipe or appurtenances and requires alterations in the work to eliminate the conflict or avoid endangering effects on either the existing or proposed facilities, the Contractor shall immediately notify the Engineer and the Owner of the affected structure. When any JANUARY, 1993 4000-9 -T - existing facilities are endangered by the Contractor's operations, he shall cease his operations at the site and take such precautions as may be necessary to protect the inplace structures until a decision is made as to how the conflict will be resolved. Without specific authorization from the utility owner, no essential utility service shall be disrupted, nor shall any change be made in either the existing structures or the planned installations to overcome the interfcJ.cuces. Alterations to existing facilities will be allowed only when that service will not be curtailed unavoidably and then only when the encroachment or relocation will satisfy all applicable regulations and conditions. Wherever alterations are required as a result of unforeseen underground interferences not due to any fault or negligence of the Contractor, the Engineer will issue a written change order covering any additional or extra work involved and specifying the revised basis of payment, if any. Any alterations made strictly for the convenience of the Contractor shall be subject to prior approval and shall be at the Contractor's expense. No extra compensation will be allowed for delays caused by the interference of underground structures unless approved by the Engineer and included in a change order. F. RemrtV::I La,f Snn;:lce T mprovement~ Removal of surface improvements in connection with trench excavation shall be limited to actual needs for installation of the pipeline and appurtenances. Removal operations shall be coordinated effectively with the excavation and installation operations as will cause the least practical disruption of traffic or inconvenience to the public. Removed debris shall not be deposited at locations that will restrict access to fITe hydrants, private driveways, or other essential service areas. Removal and final disposal of debris shall be accomplished as a single operation wherever possible and the debris shall be removed from the site before starting the excavating operations. Removal of concrete or bituminous structures shall be by methods producing clean-cut breakage that will preserve the remaining structure without damage. Concrete or bituminous paving shall be removed so when the trench is excavated there will be a six inch wide minimum undisturbed subgrade and aggregate base course lip. Removal equipment shall not be operated in a manner that will cause damage to the remaining or adjoining property. Where not removed to an existing joint, concrete structures shall be sawed along the break lines to a minimum depth of one-third of the structure depth. Any reusable materials or materials for J.,^-ycling, such as asphalt, concrete, aggregate, sod or topsoil, shall be segregated from other waste materials and be stockpiled so as to maintain suitability and permit proper reuse. JANUARY. 1993 4000-10 G. FX~::Iv::ltion ::Inn Trf"n~}l 'Prep::lT::ltinn Excavating operations shall proceed only so far in advance of pipe laying as will satisfy the needs for coordination of work and permit advance verification of unobstructed line and grade as planned. Where interference with existing structures is possible or in any way indicated, and where necessary to establish elevation or direction for connections to inplace structures, the excavating shall be done at those locations in advance of the main operation so actual conditions will be exposed in sufficient time to make adjustments without resorting to extra work or unnecessary delay. All installations shall be accomplished by open trench construction except where boring and jacking or tunnel construction methods shall be employed as specifically required by the Plans or approved by the Engineer. Surface structures must be properly supported and the backfill restored to the satisfaction of the Engineer. The excavation operations shall be conducted to carefully expose all inplace underground structures without damage. Wherever the excavation extends under or approaches close to an existing structure as to endanger it in any way, precautions and protective measures shall be taken as necessary to preserve the structure and provide temporary support. Hand methods of excavating shall be utilized to probe for and expose such critical or hazardous installations as gas pipe and power or telephone cables. G.l rl::1~~lfi~~tion an.ri nl~~ltlon rtf M::Itp.ri::ll~: All materials encountered in the excavations, with the exception of items classified for payment as structure removals. will be considered as Unclassified Excavation. Unclassified materials shall include muck, rubble, wood debris~ boulder stone, masonry or concrete fragments less than one cubic yard in volume, together with other miscellaneous matter that can be removed effectively with power operated excavators. Excavated materials will be classified for reuse as being either Suitable or Unsuitable for backfill or other specified use, subject to selective controls. All suitable materials shall be reserved for backfill to the extent needed, and any surplus remaining shall be utilized for other construction on the project as may be specified or ordered by the Engineer. To the extent practical, granular materials and topsoil shall be segregated from other materials during the excavating and stockpiling operations so as to permit best use of the available materials at the time of backfilling. All excavated materials reserved for backfill or other use on the project shall be stored at locations approved by the Engineer that will cause a minimum nuisance or of inconvenience to public travel, adjacent properties, and other special interests. The material shall not be deposited so close to the edges of the excavations as would create hazardous conditions, nor shall any material be placed so as to block the access to emergency services. All materials considered unsuitable by the JANUARY. 1993 4000-11 T Engineer, for any use on the project, shall be immediately removed from the project and be disposed of as arranged for by the Contractor. G.2 'Rx(";Iv::Itlnn T ,1rnlt~1ion~ ::Inn Reqnlrement~: Trench excavating shall be to a depth that will Jk'uuit preparation of the foundation, as specified, and installation of the pipeline and appurtenances at the prescribed line and grade except where alterations are specifically authorized. Trench widths shall be sufficient to permit the pipe to be laid and joined properly and the backf1l1 to be placed and compacted as specified. Extra width shall be provided as necessary to permit convenient placement of sheeting and shoring and to accommodate placement of appurte- nances. G.3 JANUARY, 1993 Excavations shall be extended below the bottom of structure grade as necessary to accommodate any required Granular Bedding material. When unstable foundation materials are encountered at the established !).lClde, additional materials shall be removed as specified or ordered by the Engineer to produce an acceptable foundation. All excavations below grade shall be to a minimum width equal to the outside pipe diameter plus two (2) feet. Trench widths shall allow for at least six inches of clearance on each side of the j oint hubs. The maximum allowable width of the trench at the top of pipe level shall be the outside diameter of the pipe plus two feet. The width of the trench at the ground surface shall be held to a minimum to prevent unnecessary destruction of the surface structures while maintaining safe working conditions. The maximum allowable trench width at the level of the top of pipe may be exceeded only by approval of the Engineer, after his consideration of pipe strength and loading relationships. Any alternate proposals made by the Contractor shall be in writing, giving the pertinent soil weight data and proposed pipe strength alternate, and shall be made in a timely manner so as not to delay the project. Approval of alternate pipe designs shall be with the understanding that no extra compensation will be allowed for any increase in material or construction costs. Shf"Ptlna ~nrl Rrn~;n(J Fxc::lv::lt;nn~: All excavations shall be sheeted shored and ~ - , ,. braced as will meet all requirements of the applicable safety codes and regulations; comply with any specific requirements of the Contract; and prevent disturbance or settlement of adjacent surfaces, foundations, structures, utilities, and other properties. Any damages to the work under contract or to adjacent structures or property caused by settlement, water or earth pressures, slides, cave-ins, or other causes due to failure or lack of sheeting, shoring, or bracing or through negligence or fault of the Contractor in any manner shall be repaired by the Contractor at his expense and without delay. Where conditions warrant extreme care, the Contractor shall exercise special precautions to protect life or property. This may include the installation of sheet 4000-12 piling of the interlocking type or shall include other safety measures be taken as the Contractor deems necessary. The Contractor shall at all times be responsible for protection of life, property, and the work on the project. The Contractor shall assume full responsibility for proper and adequate placement of sheeting, shoring, and bracing, wherever and to such depths that soil stability may dictate the need for support to prevent displacement. Bracing shall be so arranged as to provide ample working space and so as not to place stress or strain on the inplace structures to any extent that may cause damage. Sheeting, shoring and bracing materials shall be removed only when and in such manner as will assure adequate protection of the inplace structures and prevent displacement of suppOrted grounds. Sheeting and bracing shall be left in place only as required by the Contract. Otherwise, sheeting and bracing may be removed as the backfilling reaches the level of respective support. Wherever sheeting and bracing is left in place, the upper portions shall be cut and removed to an elevation of three (3) feet or more below the established surface grade or as the Engineer may direct. All costs of furnishing, placing and removing sheeting, shoring and bracing materials, including the value of materials left in place as required by the Contract, shall be included in the prices bid for pipe installation and will not be compensated for separately. When any sheeting, shoring, or bracing materials are left in place by written order of the Engineer, payment may be made for those materials as an extra work item, including waste material resulting from upper cut-off require- ments. G.4 Prep~r~tlon ~nci M~lntPn::lnrp of Fnllnn::lt;on~: Foundation preparations shall be conducted to produce a stable foundation and provide continuous and uniform pipe bearing between bell holes. Where Class C bedding is specified the initial excavating or backfilling operations shall produce a subgrade level slightly above finished grade to permit hand shaping to finished grade by trimming of high spots and without the need for filling of low spots to grade. In excavations made below grade to remove unstable materials, the backfilling to grade shall be made with Granular Foundation material. Placement of the backfill shall be in relatively uniform layers not exceeding eight (8) inches in loose thickness. Each layer of backfill shall be compacted thoroughly, by means of approved mechanical compaction equipment, to produce uniform pipe support throughout the full pipe length and facilitate proper shaping of the pipe bed. Where the foundation soil is found to consist of materials that the Engineer considers to be so unstabl~ as to preclude removal and replacement to a reasonable depth to achieve solid support, a suitable foundation shall be constructed as the Engineer directs in the absence of special requirements therefore in the Contract. JANUARY, 1993 4000-13 T The Contractor shall be required to furnish and drive piling and construct concrete or timber bearing supports or other work as provided for in an extra work order. Care shall be taken during final subgrade shaping to prevent any over-excavation. Should any low spots develop, they shall only be filled with Granular Foundation material, which shall be compacted thoroughly, without additional compensation provided to the Contractor. The fInished subgrade shall be maintained free of water and shall not be disturbed during pipe lowering operations except as necessary to remove pipe slings. The discharge of trench dewatering pumps shall be directed to natural drainage channels or storm water drains in a manner which does not cause damage to private or public property. Any debris left by dewatering operations shall be cleaned up immediately by the Contractor. Draining trench water into sanitary sewers or combined sewers will not be permitted. The Contractor shall install and operate a dewatering system of wells or points to main tain pipe trenches free of water whenever necessary or as directed by the Engineer to meet the intent of these specifications. Unless otherwise specified in the Plans, Specifications, or Specific Requirements, such work shall be considered incidental with no additional compensation provided therefore. All costs of excavating below grade and placing foundation or bedding aggregates as required shall be included in the bid prices for pipe items to the extent that the need for such work is indicated in the Contract provisions and the BID does not provide for payment therefore under separate BID items. If examination by the engineer reveals the need for placement or foundation aggregates was caused by the Contractor's manipulation of the soils in the presence of excessive moisture or lack of proper dewatering, the cost of the corrective measures -shall be borne by the Contractor. H. Tn~t~l1~t;on of P;pe ~nrt FiJ:tings Inspection, handling, and all aspects of the installation of the pipe, services, and appurtenances shall be in accordance with the manufacturer's recommendations, and as supplemented as follows: R.l Tn~pe~tlon ::Inn H::mnl1ne: Proper and adequate implements, tools, and facilities shall be provided and used by the Contractor for the safe and convenient prosecution of the work. Unloading, distribution, and storage of pipe and appurtenant materials on the job site shall be at a location approved by the Engineer. All materials shall be handled carefully, as will prevent damage to protective coatings, linings, and joint fittings; preclude contamination of interior areas; and to avoid jolting contact, dropping or dumping. JANUARY, 1993 4000-14 Before being lowered into laying position, the Contractor shall make a thorough visual inspection of each pipe section and appurtenant units to detect damage or unsound conditions that ma.y need corrective action or be cause for rejection. Inspection procedure shall be as approved by the Engineer, with special methods being required as he deems neces~ to check out suspected defects more definitely. The Contractor shall infVUll the Engineer of any defects discovered and the Engineer will prescribe the required corrective action or order rejection. Immediately before placement, the joint surfaces of each pipe section and fitting shall be inspected for the presence of foreign matter, coating blisters, rough edges or projections, and any imperfections so detected shall be corrected by cleaning, trimming, or repairs as needed. H.2 Pipe T ~ying ~rntion~: Trench excavation and bedding p.lcparations shall proceed ahead of pipe placement as will permit proper laying and joining of the units at the prescribed grade and alignment without unnecessary deviation or hindrance. All foreign matter or dirt shall be removed from the inside of the pipe and fittings before they are lowered into position in the trench and they shall be kept clean by approved means during and after laying. The sewer materials shall be carefully lowered into laying position by the use of suitable restraining devices. Under no circumstances shall the pipe be dropped into the trench. At the time of pipe placement, the bedding conditions shall be such as to provide uniform and continuous support for the pipe between bell holes. Bell holes shall be excavated as necessary to make the joint connections, but they shall be no larger than would be adequate to suppon the pipe throughout its length. No pipe material shall be laid in water nor when the trench or bedding conditions are otherwise unsuitable or improper. When placement or handling precautions prove inadequate, in the Engineer's opinion, the Contractor shall provide and install suitable plugs or caps effectively closing the open ends of each pipe section before it is lowered into laying position, and they shall remain so covered until removal is necessary for connection of an adjoining unit. Unless otherwise pennitted by the Engineer, bell and spigot pipe shall be laid with the bell ends facing UP5.ld.de and the laying shall start on the downgrade end and proceed upgrade. As each length of bell and spigot pipe is placed in laying position, the spigot end shall be centered in the bell and the pipe forced home and brought to correct line and grade. The pipe shall be secured in place with approved backfill material, which shall be thoroughly compacted by tamping around the pipe out to the trench wall. JANUARY, 1993 4000-15 [ Connection of pipe to existing lines or previously constructed manholes shall be accomplished as shown in the Plans or as otherwise approved by the Engineer. All structure penetrations shall be made with the use of waterstop seals. At all times when pipe laying is not in problcSs, including noon hour and overnight periods, all open ends of the pipe line. shall be closed by watertight plugs or other means approved by the Engineer. If water is present in the trench, the seals shall remain in place until the trench is pumped completely dry. Installation of PV C, shall conform to ASTM D 2321. Unless otherwise noted in the Specific Requirements, pipe bedding shall be Class B. I.

Each test section of the sewer shall be subjected to ex filtration testing, by air test method or when approved by the Engineer by hydrostatic method as described below. The requirements set forth for maximum leakage shall be met as a condition for acceptance of the sewer section represented by the test. All testing shall be performed by the Contractor at his expense without any direct compensation being made therefore, and he shall furnish all necessary equipment and materials, including plugs and standpipes as required. In the event of test failure on any test section, testing shall be continued until all leakage has been detected and corrected to meet the requirements. All repair work shall be subject to approval of the Engineer. Introduction of sealant substances by means of the test water will not be permitted. Unsatisfactory repairs or test results may result in an order to remove and replace pipe as the Engineer considers necessary for test conformance. All repair and replacement work shall be at the Contractor's expense. c.! Air Te~t Method: The section of sewer pipe shall be clean, and the pipe may be wetted. Pneumatic balls shall be used to plug each end of the test section at a JANUARY, 1993 4000-26 manhole. The testing gauge shall be located at ground level, out of the manhole, and have dial increments of 0.1 psi or less. Low pressure air shall be introduced into the line until the gauge pressure reaches 4.0 psi plus the incremental back pressure due to the average height of ground water above the pipe. The incremental back pressure on the pipe to be added due to the average height of ground water above the pipe shall be determined by dividing the average height by 2.31. The following table summarizes these values for heights of 1-10 feel Average Height of Ground W::Iter T::Ihle Ahovp: P;pe... 1 foot 2 feet 3 feet 4 feet 5 feet 6 feet 7 feet 8 feet 9 feet 10 feet Incremental Back Pressure to be AddPli to 4 0 p~;g 0.43 psig 0.86 psig 1.29 psig 1.72 psig 2.16 psig 2.59 psig 3.01 psig 3.44 psig 3.87 psig 4.30 psig The sewer section under test will be accepted as having passed the air leakage test if it does not lose air at a rate to cause the pressure to drop from 3.6 to 3.0 psi in less time than one-half minute per inch in diameter of the pipe tested. Testing must be done in the presence of the Engineer. If the test fails, necessary repairs shall be made and the test performed again until acceptable. C.2 Hynro~t;lti(' Tp.~t Method: After bulkheading the test section, the pipe shall be subjected to a hydrostatic pressure produced by head of water at a depth of three feet above the invert elevation of the sewer at the manhole of the test section. In areas where ground water exists, this head of water shall be three feet above the existing water table. The water head shall be maintained for a period of one hour during which time it will be presumed that full absorption of the pipe body has taken place, and thereafter for an extended period of one hour the water head shall be maintained as the test period. During the one hour test period, the measured water loss within the test section, including service stubs, shall not exceed the Maximum Allowable V olumes given below for the applicable Main Sewer Diameter.

Testing shall be for a 2 hour duration with valves closed. The Contractor shall furnish the pump, pipe connections, temporary plugs, gauges, and measuring equipment, and shall perform the testing in the presence of the Engineer. The pressure gauge for the test shall be an Ashcroft Model 1082 with a 4-1/2 inch dial face and 1 psi increments. Where permanent air vents are not provided, the Contractor shall provide and install corporation cocks at the high points as needed for release of air as the line is filled with water. Where concrete reaction blocking is placed, the forcemain shall not be subjected to hydrostatic pressure until at least 5 days have elapsed after the concrete placement, with the exception that this period may be reduced to 2 days where high early strength concrete is used. Any defective joints, pipe fittings, or valves revealed during the testing or before fmal acceptance of the work shall be satisfactorily corrected and the test repeated until the specified requirements have been met. D.l Pre~~nTp. Tp.~t: The section being tested shall be slowly filled with water and the specified test }.I.l\:SSure shall be Cl}'}llied after all air has been expelled from the pipe. A hydrostatic }I.lc.SSure of two times the maximum design pressure, or a minimum of 70 pounds per square inch gauge pressure, measured at the lowest point of elevation, shall be applied by means of a pump connected to the pipe in a satisfactory manner. JANUARY. 1993 4000-28 The gauge pressure shall be checked after a minimum duration of 2 hours. A pressure drop of 2 psi or less will be cause to accept the test section.. Several attempts must be made to satisfy the Engineer the YJ.~ssure test will not be successful. If the drop is more than 2 psi after these attempts, the Engineer may in writing authorize the leakage test for acceptance. D.2 T p~k::lef"; Test: After an unsatisfactory pressure test, and if authorized in writing by the Engineer, a leakage test shall be perfonned on each valved section of forcemain to deU:;.l1uine the quantity of water that must be supplied into the section to maintain a test pressure of 150 pounds per square inch, after the air in the pipeline has been expelled and the pipe has been filled with water. The water added shall be recorded to the nearest fluid ounce. After filling the pipe with water and expelling all air in the line, a pressure of 2 times the maximum design pressure or a minimum of 70 psig measured at the lowest point of elevation shall be applied in the same manner as prescribed for the pressure test, and sufficient water shall be measured and supplied into the pipe section to maintain the pressure for a test duration of 2 hours.

This work incorporates the field and laboratory data information from a prior report (AbT #93- 2190), dated November 24, 1993) and the results of the recent supplemental work conducted in the Lyons/Brunswick area as outlined in our proposal to MSA Consulting Engineers dated April 4. Our total authorized field and laboratory scope includes the following: . Twenty-five (25) standard penetration test borings extending 6' to 16' deep. . Soil laboratory testing, which included R-value. SUBSURFACE ~A~LORATION General The total subsurface exploration prol,uull consisted of twenty-five standard penetration test borings. The initial fifteen borings (#1-#15) were conducted on November 12 and 15, 1993. "AN AFFIRMATIVE ACTION EMPLOYER" 2102 University Ave. w. St. Paul, MN 55114. 612-659-9001.

Fax 507-387-6999 ~1 #94-923 - Page 2 Borings #16-#25 were added in the Lyons/Brunswick area, and were performed on Apri113, 1994. The general locations of the test borings were preselected by MSA Consulting Engineers. After performing the borings, we documented the location by taping to the street centerline and a nearby cross street centerline. Please note that the N, S, E, and W directions are not necessarily true plan directions, and we assumed the direction as being para11eU~.l~ndicular to existing street centerlines. The general locations of the borings appear on the attached sketches. The more specific dimension locations appear on each individual boring log. No surface elevations were obtained, although all borings were placed on the existing road surface. Drilline Methods The test borings were drilled with truck-mounted drill rigs, using a 3.25" (inside diameter) hollow stem auger. SamoIin& Methods Solit-Sooon Samoles (SS) Standard penetration (split-spoon) samples were collected in general accordance with ASTM:DI586. This method consists of driving a 2" O.D. split barrel sampler into the in-situ soil with a 140-pound hammer dropped from a height of 30". The sampler is driven a total of 18" into the soil. After an initial set of 6", the number of hammer blows to drive the sampler the final 12" is known as the standard penetration resistance or N-value. Samoline Limitations Unless actually observed in a sample, contacts between soil layers are estimated based on the spacing of samples and the action of drilling tools. Thus, most contacts shown on the logs are approximate, with a possible upper and lower limits of contacts defmed by the overlying and underlying samples. Determination of soil layer contact depth is even more difficult in frozen soils. Because the sub grade soils were somewhat similar in type to base materials, determination of base thicknesses was difficult. A.b 1" #94-923 - Page 3 Cobbles, boulders, and other large objects generally cannot be recovered from test borings, and they may be present in the ground even if they are not noted on the boring logs. Classification Methods Soil classifications shown on the boring logs are based on the Unified Soil Classification (USC) system. The USC system is described in ASTM:D2487 and D2488. Where laboratory classification tests (sieve analysis or Atterberg Limits) have been performed, accurate classifications per ASTM:D2487 are possible. Otherwise, soil classifications shown on the boring logs are visual-manual judgments. We have attached charts illustrating the USC system, the descriptive terminology, and the symbols used on the boring logs. The boring logs include descriptions of app3.J.\:'ut geology. The geologic depositional origin of each soil layer is inttt~}Jreted primarily by observation of the soil samples, which can be limited. Observations of the surrounding topot;J.d.phy, vegetation, and development can sometimes aid this judgment. Water Level Measurements. During the drilling operations, the boreholes were probed for the presence of ground water using a weighted measuring tape. The results of the ground water measurements are shown at the bottom of the boring logs. The following information appears under "Water Level Measurements" on the logs: . Date and Time of measurement . Sampled Depth: lowest depth of soil sampling at the time of measurement . Casing Depth: depth to bottom of casing or hollow-stem auger at time of measurement . Cave-in Depth: depth at which measuring tape stops in the borehole . Water Level: depth in the borehole where free water is encountered with the measuring tape Abl. #94-923 - Page 4 · Drilling Fluid Level: same as Water Level, except that the liquid in the borehole is drilling fluid, not ground water The true location of the water table at the boring locations may be different than the water levels measured in the boreholes. This is possible because there are several factors that can affect the water level measurements in the borehole. Some of these factors include: permeability of each soil layer in profile, presence of perched water, amount of time between water level readings, presence of drilling fluid, weather conditions, and use of borehole casing. In general, measured water levels in pervious sand deposits usually are close to actual ground water levels. In fine-grained soils (silts and clays), it may not be possible to determine true ground water levels within the normal time duration of a subsurface exploration program. In these soils, the absence of a measured water level in the borehole does not necessarily mean that ground water was not encountered or that the water table or piezometric surface was not penetrated. In mixed soil profiles, consisting of lenses and layers of widely varying soil permeabilities, extended periods of time may be necessary before the water level in the borehole matches the true water table. Therefore, the measured water levels for mixed soils may not indicate the true ground water table. LABORATORYl~lli~G The selected laboratory test program consisted of the following: . One (1) R-value test (Minnesota Modified Method) . One (1) sieve analysis test (ASTM:D422) . One (1) Atterberg Limits test (ASTM:D4318) . Nineteen (19) moisture content tests A.bl #94-923 - Page 5 The results of the sieve analysis/ Atterberg Limits tests and the R -value test are shown on the separate data sheets following the boring logs. The moisture content test results appear on the individual boring logs, opposite the samples upon which they were performed (WC column). ~lT~ COND.lIIONS Subsurface Soils/GeoloC Logs of the test borings are attached. The logs contain information concerning soil layering, soil classification, geologic description and relative density/consistency, which is based on the standard penetration resistance (N-value). It is important to note that the subsurface conditions only indicate the material classification! properties at the sampled locations and variations do occur between and beyond borings. The geology depicted by the borings is variable. Much of the native soils are glacially deposited tills, classified as sandy lean clays (CL) and clayey sands (SC). However, the tills are often overlain or interbedded with alluvial deposits ranging from sands (SP) to lean and fat clays (CL and CH). Water deposited (alluvial) soils are predominant in the Lyons/Brunswick area. Many of the borings include mixed fill over the natural profile with soil types generally similar to the variable underlying native soils. The fill occasionally includes black (suggesting organic) soils, and topsoil layers occasionally underlie the fill. The topsoil is judged to be significantly high in organics at Boring Location #13 (Creekside Circle). The N-values suggest the soils have variable density or consistency, indicating that soil stability properties should also be variable. Often, the upper sample (within 2' of the surface) appears to have a moderate to high stability, although many of the samples from 2' to 3th' deep suggest reduced stability. T AbT #94-923 - Page 6 The more recent borings in the L yons/Brunswick area again suggest that mostly alluvial sands and clays are present which are overlain by fill. Again, many of the alluvial clays and portions of the fill are judged to have low stability properties. Based on sample appearance and moisture content, we judge Borings #19, #20, and #21 to have relatively good stability. Conditions at Borings #24 and #25 are also judged marginally favorable. However, subcuts approaching the fine alluvium at Boring #25 may result in reduced stability under the construction traffic. Groundwater Conditions Measurable ground water levels were noted at four locations (#6 below Northwood Road; and #12, #22, and #23 below Brunswick Avenue). We judge the water level in the Brunswick area to be perched water, as we did observe that the surface water is directed towards this area and standing water was noted to be present at the surface. Other lower elevation areas in the L yons/Brunswick area were also noted to include standing water at the surface. The recorded level at Boring #6 may represent a true ground water level. Boring #5 also included a wet sample around 10' deep suggesting a possible water level. The soil profile at these two locations are slow draining, and if given more time, a water level may actually rise to a shallower depth. You should expect ground water levels to fluctuate in the future. Fluctuations occur due to varying seasonal and yearly rainfall and snow melt, as well as other factors. CONSIKUCTION CONSIDJY<ATIONS New subgrade fill should be placed and compacted per MnDOT Specification 2105.3F1 (Specified Density Method). This specification requires a compaction level of 100% within the upper 3' zone; and also includes a requirement for moisture content such that proper stability can be attained. Where silty or clayey soils are allowed as fill, we caution that the soil may need to be moisture conditioned to meet the compaction and moisture requirements. We caution Al: 1 #94-923 - Page 7 that moisture conditioning of soils can be time consuming, labor intensive and will require favorable weather. Also, lack of compaction/stability of underlying soils may make attaining compaction in new fill or reworked soils more difficult. Ground water or wetlwaterbearing soil conditions may appear within utility trench excavations or road subcuts which significantly increases the potential for soil disturbance. This condition may require the need for dewatering, or the use of coarser sand/rock fill soils to improve stability . The trench excavation sidesloping should meet the requirement established in the OSHA 29 L~.K, Part 1926, Subpart P, "Excavation and Trenches." The contractor should be responsible for trench safety. Even with the required OSHA sloping, ground water can induce sideslope running or ravelling which may require that retention or more extensive dewatering be performed.
