Mr. Bruce Westby July 18, 2023 Page 3 Utility Coordination We have already completed a full GSOC design locate for the original plans. But due to the time elapsed, we will initiate another full Gopher State One Call locate to pick up any new or modified private utility lines since 2021. We will coordinate with the surveyors to locate all marked locations as part of our topographic survey of the revised plan sheet project areas. The team will also use their expertise to lay out the right- of-way boundary and adjacent properties for the project area. This information will be essential for creating an accurate base map file and Digital Terrain Model. Identification of potential conflicts or utility improvement needs and ongoing coordination with the public and private utility companies are key components for a smooth -running project. The SEH team proposes to review with the utility companies at the start of the project (after the topographic survey and existing water main locating performed by the City of Ramsey). This is proposed for two purposes: to inform the utilities of the updated project re -design and schedule, to gather the most accurate information from them about the existing utilities, and to verify all utilities were captured by our topographic survey. Additional time for coordination has been included in the proposal for potential coordination with affected utilities. Preliminary Design Prior to going into final design and preparation of bidding documents, we will meet with the City to review all the changes made at the request of the City for the rebidding process to confirm we have captured all the new water main facilities and identified the correct locations for open cut versus HDD. At this meeting we will also confirm the final details of the 143rd Ave NW Street design to be incorporated into the plans. It would be desirable to minimize any pavement or curb replacement as part of this project due to the heavy construction traffic that will use this road during the WTP construction and access to adjacent commercial properties. This task includes the design of the meter vault and all associated disciplines to prepare the plan sheet and technical specifications, i.e. process piping, electrical, mechanical, etc. Final Design After the preliminary design meeting for the revised water main plans is complete, Dave will lead the team into final design of the proposed improvements to meet the deadline of bidding this project in fall of 2023. The chosen installation approach of the water main will be designed to meet the AWWA, MDH and City of Ramsey standards. This will include design of impacted infrastructure such as trails, pedestrian ramps, driveways, storm sewer, sanitary sewer, curbing and miscellaneous restoration items. An updated Project Manual and final Engineer's Estimate will be developed. In discussions with the City, SEH will set up the final bid schedules and details that may be different from the option used last time which was to bid both open cut and HDD to allow contractors to choose their method of installation. SEH will submit for needed agency reviews and permits. Bidding Documents & Bidding Process SEH will prepare the project specifications and bidding package, and the project can be advertised once City Council approval of the plans has been completed. SEH's project manager and technical experts will be available throughout the bidding process for questions. We will attend the bid opening and analyze the bids in order to give a contract award recommendation to the City. SEH will provide all project base files to the City in AutoCAD Civil 3D as well as all digital plan sheets.
