About this file
This is a bid set document prepared by BEAM Professionals for Mt. San Antonio College, a California community college district located in Walnut, California. The project involves roofing repairs and partial replacements at four buildings (2M, 2T, 9A, and 69) to address deteriorated roofing systems and water intrusion issues. The scope of work includes selective demolition of existing modified bitumen roof membranes down to the structural deck, replacement with SikaShield modified bitumen systems or approved alternates, installation of new coverboard and insulation, replacement of parapet cap flashing, brick cap flashing, and retrofit drain kits. Building 2M requires complete roof system replacement, while Buildings 2T, 9A, and 69 involve field membrane preservation with selective component replacement. The total roof area across all buildings is approximately 97,453 square feet, subdivided into multiple designated zones (A1-A23 for Buildings 2M and 2T, A1 for Building 9A, and A1-A4 for Building 69). A mandatory job walk is scheduled for June 30, 2026, at 9:00 a.m., with prequalification applications due July 7, 2026, at 2:00 p.m. Only contractors receiving a Prequalification Approval Letter will be eligible to bid in the subsequent formal bidding phase.
Contractors must hold a current California Contractor's License classification C-39 (Roofing) and be Department of Industrial Relations registered. The District has established a three percent Disabled Veteran Business Enterprise (DVBE) participation goal and a Community Workforce Agreement requiring prevailing wage compliance, apprentice utilization up to 30 percent of the craft workforce, and a 30 percent local resident employment goal. Contractors must be manufacturer-certified applicators eligible to obtain 20-year full system warranties and 5-year applicator warranties. Prequalification requirements include financial capacity demonstrated through reviewed or audited financial statements (the lesser of ten times working capital or ten times net worth), minimum combined comprehensive single-limit liability insurance of $2,000,000, proof of bondability from an admitted California surety with an A- rating or better, and completion of at least two public works building projects within the past five years in California. Prequalification scoring uses a maximum of 86 points, with a minimum of 70 points required to qualify. Bid security of ten percent of the maximum bid amount will be required in the subsequent bidding phase.
