VII.1. Approve Final Plans and Order Bids – 2022 Trunk Watermain Rehabilitation, City Project 2021-05; KlingbeilJanuary 31, 2022 Council Report 2022-010 APPROVE FINAL PLANS AND ORDER BIDS 2022 TRUNK WATERMAIN REHABILITATION CITY PROJECT 2021-05 Proposed Action Staff recommends the following motion: adopt Resolution 2022-04, Resolution Approving Plans and Specifications and Authorizing Advertisement for Bids, 2022 Trunk Watermain Rehabilitation, City Project 2021-05. Overview At its September 14, 2021 work session, council was presented the preliminary engineering report undertaken to investigate rehabilitation of the City’s trunk watermain system in the area of the Water Treatment Plant and at its October 19, 2021 meeting, the Hopkins City Council ordered the above mentioned improvement. The final plans are complete, staff now asks the Council to approve these plans and authorize advertisement for bids. Primary Issues to Consider Scope of Improvements Public Input Estimated Costs and Funding Project Schedule Staff Recommendation Supporting Information Engineer’s Estimate Final Plans (available upon request) Project Location Map Resolution 2022-04 _________________________________ Eric Klingbeil, P.E., City Engineer Financial Impact: $4,170,000 Budgeted: Y/N _Y_ Source: _PIR, Water, Sanitary, Storm Related Documents (CIP, ERP, etc.): CIP _ Notes: _________________________________________ Council Report 2022-010 Page 2 ANALYSIS OF ISSUES Scope of Improvements This project includes rehabilitation of the trunk watermain system in the area of our Water Treatment Plant and several watermain crossings under TH 7. These sections of the water distribution system have exceeded their useful life and are in need of rehabilitation and/or replacement. A mixture of CIPP (cured in-place pipe) rehabilitation, HDD (horizontal directional drilled) replacement, and traditional open-cut replacement are the most cost effective and least disruptive methods to rehabilitate these sections of the water distribution system. Public Input A public information meeting regarding the improvements were held on January 5th. This meeting was a hybrid in-person and online presentation focusing on the overall project scope, impacts, and schedule. The meeting was also recorded and are available on the project website, www.hopkins-trunkwatermain.com. Bolton & Menk and City staff will continue to meet with individual property owners, property managers, and residents in person to discuss concerns and look at options to minimize issues. Project Budget and Costs The estimate for this project, which includes contingency, and costs for legal, administrative, and engineering costs for all the work, totals to $4,170,000. This is a base project cost of $4,060,000 and an add alternate of $110,000. The CIP amount for this project is $3,955,000. Cost estimates show the project tracking slightly higher than the CIP budget. This is due to additional work outside the original scope included with the project, additional work required due to conflicts with private utilities, and conservative estimates for contingencies and soft costs. One portion of the project is updating the watermain crossing at 12th Avenue N, this will be bid as an “Add Alternate”. We will have the option of moving forward with this item or to remove it from the project once bids are received, based on budget constraints. Council Report 2022-010 Page 3 Cost estimates show the base project is very close to the CIP budget. The total project with the add alternates is above the project budget, but council has the option of awarding the add alternate or not once bids have been received.
