Basin 4 Collection System Improvements

The City of San Mateo Public Works Department issued solicitation 46S004 for the Basin 4 Collection System Improvements project to secure a qualified engineering consulting firm for professional design, bidding, and construction services. With an estimated total project cost of 31 million dollars, the scope of work involves the design of approximately 15,000 feet of new parallel and upsized gravity sewers ranging from 10 to 24 inches, as well as the rehabilitation and repair of a pump station to mitigate sanitary sewer overflows and ensure regulatory compliance. The project is divided into three negotiation phases encompassing alternatives analysis, preliminary and final design, bid phase support, and construction phase services. Proposals were required to be submitted by February 23, 2017, and led by a licensed California Professional Engineer with a minimum of 10 years of experience. The contract is governed by a professional consultant services agreement that defines the roles, responsibilities, and payment terms, including a detailed rate and cost schedule based on hourly charges with a maximum annual increase of 3 percent. Addendum No. 1 modified the original request by providing record drawings for the Santa Clara Pump Station and removing the LOE and Fee Schedule section. The project management is overseen by David Wingate, the Contract Manager for the Clean Water Program.
