Imperial Dam Potable Water Tank Replacement, AZ

The Department of the Interior Bureau of Land Management is seeking a contractor to replace the potable water tank at the Imperial Dam Long Term Visitor Area in Arizona. The project involves removing the existing tank and foundation, then installing a new 85,000-gallon cylindrical steel tank that must comply with California Building Code and American Water Works Association standards, including a float switch control system and reconnection of electrical and telemetry components. The contractor must engage a California-licensed Professional Engineer for permitting, construction certification, and regulatory compliance. This is an Invitation for Bid (IFB) using sealed bidding procedures with a 20% bid guarantee requirement and performance and payment bonds. The current submission deadline is July 18, 2025 at 2:00 PM Mountain Time, with the bid opening scheduled for July 23, 2025 at 12:00 PM Mountain Time following multiple amendments that extended the original deadlines.

This procurement is designated as a total small business set-aside under NAICS code 237110 (Water and Sewer Line and Related Structures Construction) with a small business size standard of $45.0 million. The contract requires 15% self-performance by the prime contractor and includes a 365-day performance period from notice to proceed. The project is located at the Imperial Dam Long Term Visitor Area in Winterhaven, California, though the solicitation references Arizona in its title. A mandatory site visit was conducted on June 12, 2025, and the site is accessible only on foot due to a swing gate restricting vehicle access. No incumbent contractors are identified in the documentation, and while specific contract values are not disclosed, the project involves heavy construction work with detailed wage determination requirements under the Davis-Bacon Act for Imperial County, California.
