The purpose of this investigation is to identify and evaluate soil properties associated with the site with respect to building a new foundation under an existing single family house. The Building Inspector, Mr. Bernie Feidt, is concerned with the lateral stability of the soils due to the existing house being close to the bluffline overlooking Prior Lake. One boring was performed to nominal depth of 20:1: feet within the project area. From the resulting data, conclusions are drawn regarding site suitability for the proposed use and recommendations are presented regarding site correction procedures and foundation and slab design. SCOPE OF SERVICES The client authorized the following scope of services: Perform One (1) standard penetration test boring to nominal depth of 20:1: feet below grade or refusal. Sample soil using a2" G.D. split-barrel sampler driven into the soil by a 140 lb weight falling 30". After an initial set of6", the number of blows required to drive the sampler an additional 12" is known as the penetration resistance or N-value. The N-value is an index of the internal friction of cohesionless soil, the consistency of cohesive soils, and the density of all soils. Sampling will conform to the methods set forth in ASTM procedure D1586-84. Classify recovered soil samples by the Visual-Manual method in accordance with ASTM D- 2488. Representative portions of the samples may be submitted to the laboratory for further examination and for verification of the field classification in accordance with ASTM D2487- 85. Information indicating depth and identification of the various strata, the N-value, water level information and pertinent information regarding the drilling method will be documented on comprehensive soil boring logs. Prepare an engineering report including a log of each boring, a diagram indicating the boring location along with our recommendations for foundation types and depths, allowable soil bearing pressures and estimates of foundation settlement. The purpose of this report is to present the results of our field and laboratory exploration assessment and the associated engineering review. Please note that this report is for geotechnical purposes only and is not intended to document the presence or absence of any environmental contaminants that could be present at the site. 1 BORING LOCATIONS AND ELEVATION The number of borings, locations and pattern were determined by the Client and Development Engineering. Insofar as possible, compromising as necessary due to factors such as access conditions, terrain, obstacles, etc, borings were placed as directed in an attempt to obtain geotechnical data representative of the site. Overhead power lines dictated the boring location attempting to get as close to the house as possible. FIELD INVESTIGATION The borings were accomplished using the Standard Penetration Test (SPT) method of investigation using a Split-Barrel Sampler (SBS). SOIL BORING RESULTS Please refer to the individual boring logs for a detailed description of soils and moisture conditions encountered. Attached to the soil boring logs is a key explaining terms and entries. The depth of individual layers of soils may vary somewhat from those indicated on the logs due to unsampled intervals between split-barrel sampler tests and, most importantly, the occurrence of transition between soil layers. Also, soil profiles not in the vicinity of the borings may vary. Refusal to auger advancement was not encountered at the boring locations, indicating no bedrock to depths tested. Groundwater was not found as indicated in the Boring Logs. Groundwater levels may occur and vary according to various climatological and meteorological influences undetermined within the time frame, scope and budget allowed in this investigation. Area development patterns can also influence groundwater. Indicated results in the Boring Logs are for time and conditions oftesting only. CONCLUSIONS AND RECOMMENDATIONS The following conclusions and recommendations are based upon interpreted results of boring logs, their relation to the planned work, and other information. Because the borings represent a small portion of the site in relation to the proposed area of work, ongoing review of construction should be carried out. If excavations reveal subsurface soils of a different nature than those observed in the boring, the Geotechnical Engineer should be contacted for possibly revised recommendations (see the following "Limitations of Investigation"). 1. General Site Suitability The purpose ofthis investigation is to identify and evaluate soil properties associated with the site with respect to building a new foundation under an existing single family house. Prior Lake Building Inspector, Mr. Bernie Feidt, is concerned with the lateral stability of the soils due to the existing house being close to the bluff line overlooking Prior Lake, see enclosed Sketch Plan. The client has excavated under the existing house and was stopped by the Building Inspector for not taking out a permit. We inspected the existing basement excavation under the existing house and the soil profile matches the soil profile in the boring log. The existing footing elevations are 2 approximately I foot below existing ground grade. The proposed bottom of footing elevations will be 75 inches or 6.25 feet below existing ground grade. Addressing the concern with the lateral stability of the soils due to the existing house being close to the bluff line overlooking Prior Lake. Soils of adequate bearing capacity, which we have, should extend horizontally a distance 2 feet beyond the structure pad or footing limits and then extend outward and downward on a 1 : 1 slope to competent soil. It is upon this formula that required lateral stability should be based. Please see the enclosed detail "Normal Excavation Oversize" used in engineered fill area. The existing bluff line has a slope of 1 : 1.6 which is not as steep as our formula for lateral support of a 1: 1 slope. Based upon this lateral support formula, slope of the existing bluff line and the elevations of the proposed footings, the lateral stability of the soils under the proposed new footings and foundation have adequate lateral stability. The soils encountered in the upper 2.5 feet of the Boring was frozen and the bearing capacity could not be determined by N-values. Typically the upper 2.5 feet of the soil profile has a low bearing capacity. Based upon interpreted results of the boring, it appears that the site has minor limitations regarding suitability for construction. 2. Recommendation - I) Ordinarv Cut and Fill I) Ordinary Cut and Fill A. Initial Site Preparation For an ordinary cut and fill approach to site correction, the proposed building pad areas, oversized as necessary, should be cleared of all uncontrolled fill, organic, loose, frozen or otherwise unsuitable soil, vegetation, debris and boulders (3 "+) prior to structure or fill placement. Based upon soil boring results the following estimated minimum depths of excavation or dropping footings will be necessary. Boring 1 2.5::1:: feet the base of the excavation to be a light brown sandy lean clay with a little gravel (eL). The sandy lean clay soils encountered are frost susceptible. Recommendation for frost protection 48 inches minimum cover over the footings which are located in heated building areas and 60 inches minimum cover in unheated areas. All foundations should have outside perimeter drain tile and granular material backfill next to the foundations with a 1 foot thick clay cap at the surface to direct surface runoff away from the foundation. This granular backfill against the foundation is to prevent frost heave of the building structure. The bottom of the excavations should be compacted with a mechanical vibrating compactor prior to placing footings. If site correction occurs during winter, the base of excavation should be adequately protected from freezing. 3 Excavated organic material, uncontrolled fill, wet unstable soil or other soil contaminated with topsoil, vegetation, etc, should be disposed of offsite, or in landscaping areas, where the bearing of weight will not be required. B. Fill Placement Fill material, as required, should be mineral soil, free of debris, boulders and organic material, of such suitable moisture content that it can be readily compacted to specified levels. Fill should be placed and compacted in a manner that will allow completed compaction ofthe total fill layer to 95% of standard maximum density according to ASTM D 698. Frozen material should not be used in fill construction, nor should any part of the completed fill be allowed to freeze. Due to the presence of organic soil, vegetation, etc, there appears to be no opportunity to salvage existing fill for re-use as controlled fill. A soil compaction test should be conducted for every two feet of fill in appropriate segments of the area. Top offill should extend horizontally a distance 2 feet beyond the structure pad or footing limits. The fill surface may then extend outward and downward on a 1: 1 slope to competent soil. It is upon this formula that required lateral excavation oversizing should be based. Please see the enclosed detail "Normal Excavation Oversize". C. Inspection and Testing The Client should retain a geotechnical engineering firm to inspect excavations, make field judgments as to subsoil adequacy, and to carry out a program of field and laboratory testing of engineered fill. This firm shall be responsibility for knowledge of contents of this report and for proper interpretation and correlation of data. D. Foundations F or purposes of proposed construction, foundations and fill to support foundations must rest upon and over mineral (non-organic) soils of adequate bearing value. For a light building such as a single family residence, a target bearing capacity of2000 pounds per square foot (pst) is usually assumed. If the site is prepared as outlined above, removing unsuitable soil and placing controlled oversized fill as necessary, then strip or pad footings may be designed allowing no more than 2000 psffoundation bearing capacity. This capacity is in accordance with recommended levels of compaction of controlled fill and settlement control requirements. This should provide a factor of safety against foundation failure of approximately 3. Over-all settlement may be 1" or less, half of which would be differential. If any other footing arrangements or alternatives are considered, if foundation loadings are higher, or if soils of a significantly different nature are discovered during excavations, the office of Development Engineering should be contacted for re-analysis. 4 E. Slabs Slabs should rest upon and over mineral soil of adequate density. This density needs only to be sufficient to control settlement potential. The floor slab can be placed directly upon 2000 psf allowable bearing capacity soils at elevations at or below 2.5 feet of the existing ground surface, or upon engineered fill, compacted and tested at elevations higher than the 2000 psf allowable bearing capacity soils located 2.5 feet below existing ground surface. The maximum floor loads will not exceed 100 psf. The floor slab can be supported on compacted fill placed to attained grade. All fill supporting the floor slab should be compacted to a minimum of 95% of Standard Proctor density. This 95% compaction requirement includes utility and foundation trench backfill. If correction of soil below slab levels is not performed, or if quality control is abandoned once footing levels are achieved then some premature deterioration (cracking, settlement) over time, with early loss in value, may be anticipated. Basement Slabs should have clearance from maximum anticipated groundwater level and should be protected from intrusion by surface waters. This groundwater clearance should be four feet or more from known groundwater level if the residence are to be approved by the Department of Housing and Urban Development (DHUD) for FHA or V A financing. This advisory is obviously met at present when the assumed basement slab elevation is 5.25 feet below existing grade or less. Site grading should be controlled so that no opportunity is provided for water to enter subsoils or foundation wall backfill areas. Please refer to the standard data sheet at the end of this report entitled "Floor Slab MoistureN apor Protection". Adequate waterproofing of the foundation walls with drain tiles and sump pump should be incorporated into the house design along with a moisture barrier. If groundwater is present, one possible solution is to run an outside drain tile around the perimeter of the proposed house foundation to the city storm sewer (if city storm sewer is available in the street and is deep enough). LIMITATIONS OF INVESTIGATION The Geotechnical Engineer has prepared this report using an ordinary level of care and in accordance with generally accepted foundation and geotechnical engineering practices. Because the borings represent only a small portion of the total site and for other reasons, Development Engineering, P.A., does not warrant that the borings are necessarily representative ofthe entire site but only of the boring locations at the time of investigation. No warranty of the site is made or implied. The boring logs should only be used in preliminary design and estimating work and in conjunction with corrective procedures. 5 The scope of this report is limited strictly to geotechnical issues which include the establishment of soil profile and only those conclusions expressly made. Please note that this work is not intended to document the presence or absence of any environmental contaminants at the site, nor for identifying applicable local, state or federal laws or regulations of a non-geotechnical nature which mayor may not be applicable to this site. Further, Development Engineering, P.A., will not be held responsible for facts not disclosed to the Geotechnical Engineer. The bore hole voids were backfilled by Development Engineering using native cuttings. Some continuing settlement may occur if construction does not take place in the near future. If settlement does occur, the Client should backfill with additional soil. This report and all supporting information is furnished only to the Client and his assigns for the designated purpose. No representations to other parties or for other uses are made. Soil samples retrieved during the investigation process will be retained in the office of Development Engineering for a period 000 days from the date oftesting. After 30 days, the samples may be discarded unless a written request is received to retain the samples for a longer period.

Upon thawing, these soils will not regain their original strcngth and density The extent of heave and dcnsity/strcngth loss depends on the soil type and moisture condition. Heave is greater is soils with higher percentage offines (silts/clays) High silt content soils are most susceptible, due to their high capillary rise potential which can create ice lenses. Fine graincd soils generally heave about ';." to %" for each foot offrost pcnctration. T!;;~ .-:;u, :.:-:J!."la"c h, l" to 2" of total frost heavc. TI,;c total an,ount can be sigrufoc;:;::.ly 1;J t,dl"li,- ;i'(. lensing occurs. DESIGN CONSIDERATIONS Claycy and silty soils can be used as perimeter backfill, although the effect of their poor drainage and frost properties should be considcred. Basement areas will have special drainage and lateral load requirements which arc not discussed here. Frost heave may be critical in doonvay areas. Stoops or sidewalks adjacent to doonvays could be designed as structural slabs supported on frost footings with void spaces below. With tillS design, movcments may then occur between tile structural slab and the adjacent on-grade slabs. Non-frost susceptible sands (with less than 12% passing a #200 sieve) can be used below such areas. Depending on the function of surrounding areas, the sand layer may need a thickness transition away from tile area where movement is critical. With sand placement over slower draining soils, subsurface drainage would be needed for the sand layer. High density extruded insulation could be used within the sand to reduce frost penetration, thereby reducing the sand thickness needed. We caution that insulation placed near tile surface can increase the potential for ice glazing of tlle surface. The possible effects of adfreezing should be considered if clayey or silty soils are used as backfill. Adfreezing occurs when backfill adheres to rough surfaced foundation walls and lifts the wall as it freezes and heaves. This occurrence is most common Witll masonry block walls, unheated or poorly heated building situations and clay backfill. The potential is also increased where backfill soils are poorly compacted and become saturated. The risk of adfreezing can be decreased by placing a low friction separating layer between the wall and backfill. Adfrcezing can occur on ex1erior piers (such as deck, fence, or similar pier footings), even if a smooth surface is provided This.is more likely in poor drainage situations where backfill soils are poorly compacted and become saturated Additional footing embedment and/or widened footings below the frost zones (which includes tensile reinforcement) can be used to resist uplift forces. Specific designs would require individual analysis. CONSTRUCTION CONSIDERA nONS Foundations, slabs and other improvements which may be affected by frost movements should be insulated from frost penetration during freezing weather. If filling takes place during freezing weather, all frozen soils, snow and ice should be stripped from areas to be filled prior to new fill placement The new fill should not be allowed to frcczc during transit, placement or compaction. This should be considered in the pr~ject scheduling, budgeting and quantity estimating. It is usually beneficial to perform cold weather earthwork operations in small areas where gradc can be attained quickly rather than working larger areas where a greater amount of frost stripping may be needed If slab subgrade areas freeze, we recommend the subgrade be thawed prior to floor slab placement. The frost action may also require reworking and recompaction of the thawed subgrade. BASEMENT/RETAINING WALL BACKFILL AND WATER CONTROL DRAINAGE Below grade basements should include a perimeter backfill dI:ainage system on the exterior side of the wall. The exception may be where basements lie within free draining sands where water will not perch in the backfill. Drainage systems should consist of perforated or slotted PVC drainage pipes located at the bottom of the backfill trcnch. lower than the interior floor grade. The drain pipe should be surrounded by properly graded filter rock. Thc drain pipe should be connected to a suitable means of disposal, such as a sump pump basket or a gravity outfall A storm sewer gravity outfall would be preferred over exterior daylightll1g. as the latter may freeze during mnter For non-building, exterior retaining walls, weep holes at the base of the wall can be substituted for a drain i'lpC. BACKFILLING Prior to backfilling. damp/water proofing should be applied on perimeter basement walls. The backfill materials placed against basement walls will exert lateral loadings. To reduce this loading by allowing for drainage, we recommend using free draining sands for backfill. The zone of sand backfill should extend outward from the wall at least 2' . and then upward and outward from the wall at a 30' or greater angle from vertical. The sands should contain no greater than 12%) by weight passing the #200 sieve, which would include (SP) and (SP-SM) soils The sand backfill should be placed in lifts and compacted with portable compaction equipment TIllS compaction should be to the specified levels if slabs or pavements arc placed above. Where slab/pavements arc not above, we recommend capping the sand backfill with a layer of clayey soil to minimize surface water infiltration. Positive surface drainage away from the building should also be maintained. Backfilling with silty or clayey soil is possible but not preferred. These soils can build-up water which increases lateral pressures and results in wet wall conditions and possible water infiltration into the basement. If you elect to place silty or clayey soils as backfill. we recommend you place a prefabricated drainage composite against the wall which is hydraulically connected to a drainage pipe at the base of the backfill trench. High plasticity clays should be avoided as backfill due to their swelling potential. LATERAL PRESSURES Lateral earth pressures on below grade walls vary, depending on backfill soil classification, backfill compaction and slope of the backfill surface. Static or dynamic surcharge loads near the wall will also increase lateral wall pressure. For design. we recommend the following ultimate lateral earth pressure values (given in equivalent fluid pressure values) for a drained soil compacted to 95% ofthe standard Proctor density and a level ground surface. Equivalent Fluid Density Soil Type Active (pet) At-Rest (pet) Sands (SP or SP-SM) 30 45 Silty Sands (SM) 40 60 Fine Grained Soils (SC. CL or ML) 70 90 Basement walls are normally restrained at the top which restricts movement. In this case. the design lateral pressures should be the "at-rest'" pressure situation. Retaining walls which are free to rotate or deflect should be designed using the active case Lateral earth pressures will be significantly higher than that shown if the backfill soils are not drained and become saturated. '. FLOOR SLAB MOISTUREN APOR PROTECTION Floor slab design relative to moisture/vapor protection should consider the type and location of two elements, a granular layer and a vapor membrane (vapor retarder, water resistant barrier or vapor barrier). In the following sections, the pros and cons of the possible options regarding these elements will be pres~nted, such that you and your specifier can make an engineering decision based on the benefits and costs of the choices. ' GRANULAR LAYER In American Concrete Institute (ACI) 302.1-96, a "base material" is recommended, rather than the conventional cleaner "sand cushion" material. The manual maintains that clean sand (common "cushion" sand) is difticult to compact~d maintain until concrete placement is complete. ACI recommends a clean, fine graded materin~ . "'; l.h at least ] 0% to 30% of particles passing a ii 1(,,: ,:ievcj '.vhich is IIOt wntaminated w;:':i day, Silt or organic m,'k.i<.L:. 'he r~ier Yl'" ll~ ACl 30.2.1-96 for additional detaiis regarding the requirements for the base material. In cases where potential static water levels or significant perched water sources appear near or above the floor slab, an underfloor drainage system may be IIeeded whereiII a draintile system is placed within a thicker clean sand or gravel layer. Such a system should be properly engineered depending on subgrade soil types an rate/head or water inflow. VAPOR MEMBRANE The need for a vapor membrane depends on whether the floor slab will have a vapor sensitive coveriIIg; will have vapor seIIsitive items stored 011 the slab, or if the space above the slab will be a hIIInidity controlled area. If the project does llot have this vapor sensitivity or moisture control IIeed, placement of a vapor membrane may not be necessary. Your decision will then relate to whether to use the ACI base material or a conventional sand cushion layer. However, if any of the above sensitivity issues apply, placement of a vapor membrane is recommended. Some floor covering systems (adhesives and flooring materials) require a vapor membrane to maintain a specified maximum slab moisture content as a condition of their warranty. VAPOR MEMBRANE/~RANULAR LAYER PLACEMENT A munberr of issues should be considered when deciding whether to place the vapor membrane above or below the granular layer. The benefits of placing the slab on a granular layer, with the vapor membrane placed below the granular layer, include reduction of the following: . Slab curling during the curing and drying process. . Time of bleeding, which allows for quicker finishing. . Vapor membrane puncturing. . Surface blistering or delamination caused by an extended bleeding period. . Cracking caused by plastic or drying shrinkage. The benefits of placing the vapor membrane over the granular layer include the following: . The moisture emission rate is achieved faster. . Eliminates a potential water reservoir within the granular layer above the membrane. . Provides a "slip surface';, thereby reducing slab restraint and the associated random cracking. If a membrane is to be used in conjunction with a granular layer, the approach recommended depends 011 slab usage and the construction schedule. The vapor membrane should be placed above the granular layer when: . Vapor sensitive floor covering systems are used to vapor sensitive items will be directly placed on the slab. . The area will be humidity controlled, but the slab will be placed before the building is enclosed and sealed from rain. . Required by a floor covering manufacturer's system warranty. The vapor membrane should be placed below the granular layer when: . Used in humidity controlled area (without vapor sensitive coverings/stored items), with the roof membrane in place, and the building enclosed to the point where the precipitation will not intrude into the slab area. Considerations should be given to slight sloping of the membrane to edges where draintile or other disposal methods can alleviate potential water sources, such as pipe or roof leaks, foundation wall damp proofmg failure, fire sprinkler system activatioII, etc. There may be case:, where memurane placement may have a detrimental effect on the subgrade support system {e.g., expansive soils). In these cases, you decision will need to weigh the cost of subgrade OptiOIIS and the perfonnance risks. PRIOR LAKE INSPECTION RECORD . SITE ADDRESS 1~$If~ fJ/~tF ~/) *. NATURE OF WORK IIIEW Fi..
