Prequalification - Buildings 2M, 2T, 9A and 69 Roofing Repairs Project

Mt. San Antonio College is soliciting bids for roofing repairs and partial replacements at campus buildings 2M, 2T, 9A, and 69 in Walnut, California. The project aims to restore watertight and code-compliant conditions by addressing deteriorated roofing systems through the installation of either a reinforced fluid-applied waterproofing system or a 72-mil PVC membrane system. The scope of work includes substrate repair, the replacement of flashings, coping, and expansion joints, and ensuring all installations meet ES-1 edge metal and California Title 24 energy requirements. A 20-year full system and workmanship warranty is mandatory. The procurement process follows a Lowest Price Technically Acceptable methodology, awarding the contract to the lowest responsive and responsible bidder. Interested contractors must complete a prequalification process via the Mt. SAC eProcurement Portal, which includes a mandatory job walk on June 30, 2026, and a prequalification package deadline of July 7, 2026. Bidders must provide a 10 percent bid security and demonstrate compliance with Department of Industrial Relations registration and DVBE participation goals. Technical specifications allow for product substitutions and additive or deductive alternates, provided they are formally approved by the Architect and meet performance equivalence.
