Engine Exhaust Silencer Replacement

The Madison Metropolitan Sewerage District (MMSD) is seeking sealed bids for an Engine Exhaust Silencer Replacement project at the Nine Springs Wastewater Treatment Plant in Madison, Wisconsin. The procurement involves removing and replacing two existing engine exhaust silencers for Waukesha L7042GU V-12 engines, including four stainless steel bellows type expansion joints and two 10" stainless steel elbows. Bidders must be prequalified and submit their qualifications by April 14, 2025, with a mandatory pre-bid meeting scheduled for April 9, 2025, at 1:00 p.m. Sealed bids are due on April 29, 2025, at 11:00 a.m. local time, with a project completion timeline of 180 calendar days from the Notice to Proceed, anticipated to be June 6, 2025. The contract will be awarded to the lowest responsive, responsible bidder, with the district reserving the right to reject any or all proposals. Evaluation will likely focus on bid price, technical capability, and compliance with specifications.

The procurement does not explicitly mention specific set-aside designations or restrictions for disadvantaged enterprises. Bidders must meet substantial insurance requirements, including $2,000,000 aggregate and $1,000,000 per occurrence general liability coverage, automobile liability, and worker's compensation insurance. Liquidated damages are established at $150 per day for failure to complete work within the specified timeframe. The project is exempt from Wisconsin state sales and use taxes, and the district will retain 5% of each payment until 50% of the contract is complete. While a specific budget range is not provided, the complexity of the exhaust silencer replacement and associated infrastructure work suggests a significant capital investment.
