Director of Public Works/City Engineer City of Prior Lake 17073 Adelmann St. SE Prior Lake, MN 55372 Re: Supplemental Agreement to Provide Professional Engineering Services Mushtown Road – 180th Street Watermain Extension Dear Mr. Brotzler: WSB is pleased to provide you with our proposal for professional services for the preparation of construction documents and associated services for the extension of watermain in 180th Street and Mushtown Road. The proposed improvements include approximately 2,600 feet of 12-inch diameter watermain that provides a closed loop in the water system in this area of the City and to serve the Parkwood Estates development. Scope of Services Generally, the scope of services will include topographic survey, geotechnical evaluation, preparation of construction documents, bidding assistance, construction contract administration, construction survey staking, and preparation of record plans. The following list of tasks is proposed to complement preparation of construction documents necessary to construct the project: Task 1: Topographic Survey WSB will perform a topographic survey to identify the existing terrain features, utilities, culverts, and miscellaneous topographic features in the project corridor. ▪ Survey will include cross sections at approximately 50-foot intervals and generally will identify edge-of-bituminous, centerline, shoulder PI, ditch/boulevard. ▪ Driveways from edge of driveway to 10 feet past the right-of-way. ▪ Storm drainage features such as culverts, including inverts, pipe size and material type. ▪ Sanitary sewer manholes. ▪ Watermain gate valves and hydrants. ▪ Significant trees of 4-inch diameter and larger. ▪ Perform Gopher State One Call and survey existing utilities as marked in the project corridor. Utilities that are not marked by the utility owner will be identified on the plans by mapping information provided by the utility owner. Utilities will be represented on the plans as SUE quality level C or D. Task 2: Geotechnical Evaluation WSB will perform a geotechnical exploration and evaluation to identify general soil information in the project corridor consisting of the following items: ▪ Geotechnical Field Work and Evaluation Report o Access site with CME-55 truck mounted auger drill rig o Perform six (6) soil borings to depth of about 14.5 feet below grade ▪ If borings are extended due to unsuitable soils at termination depths Mr. Andy Brotzler, P.E. June 2, 2021 Page 2 G:\.Clients All\Prior Lake\Proposals\2021 - Mushtown Road Watermain Extension\LTR_MH_ABrotzler-060221-Mushtown Road Watermain Extension.docx (organics, fills, etc), additional depth may be required at additional cost per foot. ▪ We will utilize flashing lights, signage, and cones for traffic control and allow traffic to self-regulate around our work zone. o Samples retrieved during drilling will be returned to our laboratory where they will be reviewed, classified using the Unified Soil Classification System (USCS) and logged under the direction of a geotechnical engineer. o Select samples will be set aside for laboratory testing. We may perform routine laboratory tests on selected soil samples obtained from the exploration. o WSB will complete Gopher State One Call (GSOC) utility clearance to have public underground utilities marked. ▪ Private utilities are the responsibility of the utility owner to mark, and WSB should be notified of any private underground utilities that are onsite. o Some damage could occur to greenspace areas from normal drilling mobilization and operations. Our proposed services do not include restoration of the site to pre-conditions. o Due to recent roadway improvements in the project corridor, no borings will be taken within the bituminous pavement surfaces. o Based on the proposed boring depths to depths ( < 15 feet ), MDH well sealing notification and fees will not be required. If the borings are extended to a depth of 15 feet or more, additional fees will be charged. o WSB will prepare a geotechnical report with discussion of subsurface soil and groundwater conditions and how they may affect the construction of the watermain. Task 3: Preparation of Construction Documents (Plans and Specifications) The construction documents (plans and specifications) will be prepared in accordance with the City's engineering requirements. The plans will be prepared for horizontal directional drilling methods of construction. The plans will generally include the following sheets (or combined items on sheets) for the proposed improvements: ▪ Title sheet ▪ General Layout plan ▪ Statement of Estimated Quantities ▪ Construction Notes ▪ Typical sections (if necessary) ▪ Standard Details ▪ Existing Conditions and Removals ▪ Watermain plan and profile ▪ Temporary and permanent erosion control plans The number of plan sheets estimated for this proposal are shown in more detail on the Estimated Project Fee worksheet enclosed for your reference. Our staff will perform a GSOC design request for private utility maps, field markings for the topographic survey, GSOC design meeting and coordination with utility owners. Task 4: Agency Permits WSB staff will prepare permit applications for the PL-SLWD and Minnesota Department of Health Watermain Plan Review. The permit fees are proposed as reimbursable expenses to the project and are identified on the fee worksheet for reference. Mr. Andy Brotzler, P.E. June 2, 2021 Page 3 G:\.Clients All\Prior Lake\Proposals\2021 - Mushtown Road Watermain Extension\LTR_MH_ABrotzler-060221-Mushtown Road Watermain Extension.docx The fee estimates for work associated with permitting the proposed project within Credit River Township. include one joint meeting with the City and Township. Once the scope of work associated with permitting the project within township right of way has been defined, WSB can provide a separate fee estimate for permitting work associated with the project (Right of way, traffic control, road closures, as needed or required). Task 5: Bidding Assistance During the bidding phase of the project, WSB staff will provide assistance to the City and to plan holders in responding to pre-bid questions, clarifications, addenda (if necessary) and opening of bids. Our staff will prepare bid tabulations, bid summary and recommendation letter for consideration of awarding a contract. Task 6: Construction Administration During the construction phase, our staff will attend the pre-construction meeting, prepare the meeting agenda, and provide meeting summary notes of the discussion at the meeting. We propose to prepare construction payment vouchers on a monthly basis upon contractor application for payment, and will coordinate signatures of the contractor, city and our staff for processing. Task 7: Construction Survey and Engineering The construction services includes engineering assistance to the City for the interpretation of plans and specifications as requested, and a survey crew for construction staking services, record plan survey, and preparation of record plans for the constructed improvements. The City plans to provide a resident construction representative to observe construction activities daily, and document quantities for partial payment to the Contractor. The City representative will contact WSB to schedule construction staking, and to request clarification of plans and specifications, on an as-needed basis. Compensation Summary Our fees for the scope of services is proposed on an hourly basis, estimated as summarized below. The fee estimate is provided in a detailed format on the enclosed Estimated Project Fees Worksheet. ▪ Task 1: Topographic Survey $ 5,939 ▪ Task 2: Geotechnical Evaluation $ 5,904 ▪ Task 3: Preparation of Construction Documents $ 25,237 ▪ Task 4: Agency Permits $ 1,643 ▪ Task 5: Bidding Assistance $ 1,104 ▪ Task 6: Construction Administration $ 1,548 ▪ Task 7: Construction Survey and Engineering $ 10,805 Reimbursable Expenses (Permit Fees) $ 1,025 Total Fee $53,205 Our proposed scope and estimated fees do not include acquisition of right of way, temporary or permanent easements.
