How to bid on Retamal Dam Building and Generator for USIBWC

What the agency is buying

The International Boundary and Water Commission (USIBWC) needs a contractor to design and build a new emergency diesel generator, a metal building to house it, a concrete pad, and a modern diesel fuel tank at Retamal Dam in Mercedes, TX. The current emergency generator is no longer functional, making this replacement necessary.

The project includes site preparation, inspection of all systems and structures, debris and construction waste disposal, and quality control testing. This is a design-build project, meaning the selected contractor will be responsible for both the design and construction phases.

Key dates and deadlines

The solicitation was published on August 04, 2026. Proposals are due by August 17, 2026, at 5:00 PM ET. This is a firm deadline, and all required documents must be submitted by this time.

A site visit is listed in the solicitation. To attend, you must submit a completed Form 358 beforehand. Be sure to check the solicitation for the specific date and time of the site visit.

Who this opportunity suits

This opportunity is suitable for construction firms with expertise in design-build projects, particularly those involving generator installations, metal building construction, and concrete work. Experience with site preparation, system inspections, and quality control testing is also important.

The project requires specific warranties: at least 5 years for the generator and automatic transfer switch, and 20 years for shingles, roofing, and the roof system. Firms with a track record of providing such long-term warranties will be well-suited.
