Solicitation # 27-002
The Mattawoman Wastewater Treatment Plant (MWWTP) in Charles County, Maryland, requires turn-key design-build services to manage force main surge and transients. Following a project that increased the effluent pump station's design peak flow to 60 million gallons per day, the County is concerned that cyclical pump operations and potential pump trips could damage the 50-year-old, 54-inch diameter prestressed concrete cylinder pipe and the existing air release valve. The project involves the design and construction of a new 40-foot diameter welded steel standpipe with separate influent and effluent pipes, including a welded steel roof cover, internal ladders, safety cages, and an overflow system. Key technical requirements include the creation of a water hammer model using Bentley HAMMER software to simulate various pump trip events and adherence to NACE II or higher qualifications for the agent. The procurement process is managed by the DPW Capital Project Management office, with proposals evaluated based on a combination of team qualifications, key personnel experience, and proposed price. The project timeline allows for a design phase of up to 270 consecutive calendar days, with construction starting within 270 days of the Notice to Proceed and reaching substantial completion within 420 days of the construction start date. Contractors must provide a 5 percent bid bond, as well as performance and labor and material bonds for 100 percent of the contract price. Additionally, the design-builder must maintain professional liability insurance of at least 2 million dollars per occurrence and aggregate, and all work must comply with ADA standards and prevailing wage requirements.
