Accordion Door Replacement

The contract requires the complete removal and replacement of three existing Panelfold accordion doors at the Squad Bay facility in Martinez, California, with new commercial-grade acoustic accordion doors meeting or exceeding the specifications of Woodfold Series 4100 or Modernfold Soundmaster Series, or an approved equal. Each door must fit an opening measuring 22 feet 6 inches wide by 9 feet 6 inches high, and all work—including field verification of dimensions, demolition and disposal of the old doors, installation of heavy-duty aluminum tracks with steel ball-bearing wheels, acoustic sweep strips, and standard hardware, functional testing for smooth and plumb operation, and comprehensive site cleanup—must be performed by a contractor holding a valid California C-61/D-28 license. The project is a firm fixed-price contract, with all costs—including freight, delivery, removal, and disposal—bundled into a single total price. Proposals must be submitted electronically through BidnetDirect.com by August 11, 2026, and must include a signed cover letter, a 15-page main proposal, a detailed Statement of Experience, a fully completed price proposal, customer references, an anti-collusion statement, an addenda acknowledgement, and proof of required insurance: $1 million per occurrence and $2 million aggregate commercial general liability, $1 million automobile liability, and workers’ compensation as mandated by California law. No progress payments are allowed absent a formal written amendment. Award will be determined based on a trade-off methodology, where cost accounts for 35 percent of the evaluation score and technical approach for 30 percent, with additional points allocated to product quality and warranty (15 percent), qualifications and relevant experience (10 percent), and references and past performance (10 percent). The selected contractor must demonstrate a clear understanding of the scope, including methods for minimizing disruption to County operations, implementing quality control, and ensuring acoustic performance with a preferred STC rating of 35 or higher. A one-year workmanship warranty is mandatory, and final acceptance by the County will trigger its commencement. All work must be performed on-site at 2475 Waterbird Way, Martinez, CA 94553, and the contractor must comply with all manufacturer specifications and applicable building codes. The County requires prior written consent for any subcontracting or assignment of work, and failure to acknowledge all issued addenda in writing will result in automatic rejection.
