Greendale board awards Nan/Now Avenue water‑main replacement to Queen City Mechanical

The Greendale Board of Works and Safety voted to award the Nan/Now Avenue water‑main replacement contract to Queen City Mechanical after staff recommended the contractor following reference checks and bid evaluation. Staff discussed construction staging to avoid customer outages, the need for multiple tie‑ins and inserted valves in some locations, and a phased approach to pressure‑testing and switching customers to new lines.

Staff reported Queen City Mechanical’s base bid at $474,837 and an alternate at $47,510 and presented a combined project total discussed at $949,938 covering phases one and two. Board members noted particular technical challenges at tunnel tie‑ins and in areas where old valves are difficult to locate, and said crews will coordinate valve closures and dewatering operations to minimize service interruptions.

After questions about contingency planning, a board member moved to approve the project award and the motion was seconded; the board approved the award by voice vote. No individual roll‑call votes were recorded on the public transcript.

Next steps: staff will execute the contract paperwork with Queen City Mechanical and hold a preconstruction meeting with the contractor to review phasing, valve‑closure strategy and materials delivery before construction begins.
