(SEH®) appreciates the opportunity to submit this proposal for professional engineering services to assist the City of Prior Lake in completing the Trunk Sanitary Sewer Pipe Condition Assessment. This project’s background, scope of work, fee, and schedule are outlined below. BACKGROUND In addition to preserving the integrity of its sanitary infrastructure, inflow and infiltration (I/I) reduction is a priority to the City of Prior Lake (City). Reduction of I/I is necessary to relieve capacity restrictions and excess spending within the City’s wastewater conveyance system. With these goals in mind, the City desires to assess the condition of their vitrified clay pipe (VCP) trunk sanitary sewer and associated manholes that surround Spring Lake, Upper, and Lower Prior Lake. Selected pipe segments and manholes included in this proposal can be seen in the attached Figure 1 and include 92 sanitary manholes and 12,289 LF of VCP ranging in size from 8-inch to 10-inch in diameter. The intentions of this assessment are to ultimately develop a phased approach to necessary rehabilitation or replacement to the lakeside sanitary sewer system. Due to the proximity to the lakes, the location of these sanitary sewer segments provides unique challenges, including high groundwater and easement access. As such, a trenchless technology is an ideal method of rehabilitation, offering completely structural solutions, with minimal disturbance to surrounding areas. The most likely solution for any pipe deficiencies would be Ultraviolet (UV) Cured-in- Place-Pipe (CIPP) due to its small equipment footprint, ease of transportation to easement areas, and overall environmental benefits for the lakes and adjacent homeowners. SCOPE OF WORK Our scope of services has been developed to ensure timely completion of this project. The work components consist of collection of closed-circuit televising (CCTV) of selected trunk sanitary sewers, GIS analytical study to develop a condition ranking for each sanitary segment, and an optional task to complete 3-D manhole scanning and review. At this time, the City is not requesting SEH to provide engineering services related to the design, bidding, or construction oversight related to any potential rehabilitation that is recommended. A detail breakdown of activities included in the following tasks can be found in the attached Task Hour Budget. EXHIBIT 1 Andy Brotzler, PE April 30, 2021 Page 2 Three tasks have been identified as follows: 1) Task #1 Project Management – We have included routine project management tasks with Prior Lake and SEH team members along with phone calls or meetings as needed. We have assumed two formal meetings: 1) kickoff meeting to discuss City goals, and 2) final meeting to review findings and recommendations. 2) Task #2 Pipe Condition Assessment – This task includes the collection of CCTV data of the selected trunk sanitary sewers. The CCTV will be performed by a sub-consultant hired by SEH. This data will be assessed using GIS analytics to assign each pipe segment a condition rating based on operation/maintenance and structural defects. Based on the condition rankings, focused areas of rehabilitation will be recommended. The deliverables for this project will include a technical memorandum, with accompanying figures, that illustrate the findings of the CCTV. Based on goals of the City, recommendations of necessary rehabilitation, focused areas of rehabilitation, and estimated costs will be provided. All related CCTV and manhole files will be included as a separate submittal. 3) Optional Task #3 Manhole Inspection – This task includes the collection and review of data via 3- D manhole scanning. SEH crews will use the RapidView IBAK PANARAMO 3-D manhole scanner to produce scans of each manhole attached to a sanitary sewer pipe segment included in the study. The 3-D scans will be reviewed and given a condition rating. PROJECT TEAM The team will be led by our Project Manager Dave Hutton, Senior Project Engineer in our Civil/Trenchless division. Dave is a hands-on Project Manager and will be your primary contact during the project. Technical support and detailed pipe evaluation services will be provided by Anna Breland and manhole assessment by Spencer Cossalter, I/I expert. SCHEDULE We understand the City desires this work be completed in 2021 so the City can budget money in their CIP for 2022 to complete any necessary improvements. We are ready to begin work on the project immediately upon receiving a signed contract and notice to proceed. Our proposed schedule for this project is shown below:  May 2021 – City Council Authorization of SEH proposal and issues notice to proceed  June-July 2021 – CCTV of sewers and manhole scanning  August 2021 – GIS analytics, manhole scan review, prepare memorandum  September 2021 – Final memorandum and Meeting with City to discuss results If the City desires to design and bid the project for 2022 construction, we would be prepared to give you a design proposal upon completion of the report and City staff direction. COMPENSATION Compensation is proposed to be the hourly cost of personnel plus reimbursable expenses including equipment, reproductions and mileage. Additional services beyond the tasks and estimated hours as described can be negotiated or provided as extra work on an hourly basis. Andy Brotzler, PE April 30, 2021 Page 3 Compensation for Task #1 and Task #2, our estimated fee for this project is $56,900 with reimbursable expenses, including $48,000 for the subconsultant CCTV work. If the City chooses to include the Optional Task #3, Manhole Scanning, the cost to complete all 92 manholes would be an additional $17,000. The number of manholes scanned can be change as the project progresses. We look forward to completing this project with the City.
