SUMMARY
The Utilities Division of the Department of Public Works & Utilities replaces the City’s undersized or structurally damaged sewer mains through annual capital improvement projects. The Sewer Line Improvements Project (Project) will improve the capacity and maintain the operability of the sewer collection system by replacing approximately 4.1 miles of existing vitrified clay pipe (VCP), asbestos cement pipe (ACP), and high-density polyethylene pipe (HDPE) ranging in diameter from 6 to 12-inches with new 8, 10, 12, or 15-inch polyvinyl chloride (PVC) or HDPE. This project takes place at twenty-nine locations throughout the City (Attachment III). Approximately 3.3 miles will be replaced by traditional open-cut method, and another approximately 0.8 mile will be replaced by trenchless technology used to cross under obstructions that prohibit open-cut installation.
On June 14, 2022, four (4) bids were received. The low bid was $11,087,925, which is $2,512,075, or 18.5%, below the Engineer’s estimate of $13,600,000. Staff is requesting Council’s approval of Addendum No. 1 and No. 2, which provided minor revisions to clarify the specifications, and awarding the construction contract to the lowest bidder, Ranger, the amount of$11,087,925, and approving an Administrative Construction Contingency (change orders) budget of $1,108,793.
Furthermore, staff is requesting appropriation of additional funds in the amount of $3,067,915 from the Sewer System Replacement Fund (Fund 611).
