Kachess DAM embankment repair materials

The Bureau of Reclamation's Pacific Northwest Region is soliciting proposals for the supply and delivery of construction materials needed for Kachess Dam embankment repairs in Washington state. The procurement requires a contractor to provide 825 tons of quarry spall rock, 60 tons of 1-inch drain rock, 150 tons of clean fill, 120 tons of 3/4-inch road base, drainage pipes and fittings, and erosion control materials including geotextile fabric, straw wattles, wood stakes, and silt fence. All materials must meet detailed technical specifications and gradation requirements, with contractors required to submit test results, manufacturer's literature, and load tickets to demonstrate compliance. The solicitation follows a Lowest Price Technically Acceptable (LPTA) evaluation methodology, meaning the government will award to the lowest-priced proposal that meets all technical requirements. Proposals are due on June 13, 2025, at 1700 local time, with the original solicitation issued on June 3, 2025.

This opportunity is designated as a total small business set-aside, restricting participation to 100% small business concerns. The materials must be delivered to either the Kachess Dam site, located approximately 70 miles east of Seattle, or the Bureau of Reclamation's Yakima Field Office between August 1st and October 31st, 2025. Deliveries are restricted to work hours between 6:30 am and 4:00 pm, Monday through Friday, with contractors required to coordinate site access through the government due to restricted access routes including travel through the dry reservoir bed. The contractor is responsible for managing material piles at the delivery site, while the government will handle final material placement. Site access includes specific logistical considerations such as a 10-ton weight limit on the spillway bridge and designated turnaround locations for trailers, with exact routes to be coordinated after contract award.
