Retamal Dam Building and Generator

The United States Section of the International Boundary and Water Commission is soliciting proposals for the Design-Build of an emergency generator and building at Retamal Dam, Texas, under solicitation number 191BWC26R0005. This is a total small business set-aside under NAICS code 236220 with a small business size standard of $45 million, requiring all offerors to be certified small businesses. The project entails replacing a nonfunctional emergency generator with a new unit housed in a metal building on a new concrete pad, supported by a modern diesel fuel tank, and includes full site preparation, debris disposal, quality control testing, and system inspections. Work must be performed between 7:00 a.m. and 3:30 p.m., Monday through Friday, excluding federal holidays, and all personnel must pass through USIBWC levees for site access, with vehicles properly identified due to proximity to Border Patrol operations and adjacent US Fish and Wildlife land. Proposals must be submitted electronically as PDFs in three volumes—Business, Technical, and Pricing—via a secure FedRAMP-compliant SharePoint portal, with submissions due by August 4, 2026, at 9:00 p.m. MST. A mandatory pre-bid site visit requires completion of Form 358, and all bidders must submit SF-24 bid security, with successful offerors required to provide SF-25 performance and payment bonds backed by sureties listed in Treasury Circular 570. The contract is firm-fixed-price, governed by FAR Part 14, and includes stringent warranties: a minimum five-year warranty for the generator and automatic transfer switch and a twenty-year warranty for the roof system and shingles, as specified in Technical Specification 01.78.36. Compliance with the Buy American Act for construction materials is mandatory, and Davis Bacon prevailing wage rates apply. Contractors must adhere to SBU data handling protocols under 18 USC Sections 641, 793, 794, 798, and 952, and submit OSHA incident rate data for the past five years. Evaluation criteria include technical plan for design and construction, past performance, organizational experience, safety practices, schedule, resource value information, and submittal compliance, with award based on the most advantageous proposal through rational tradeoff between non-cost factors and price. Proposals are subject to pass/fail
