CA - Humboldt Bay NWR - Gravel

The Fish and Wildlife Service seeks delivery of virgin quarried aggregate materials (1.5" minus road base gravel with fines and 3/8" minus trail gravel with fines) to Humboldt Bay National Wildlife Refuge in California, with proposals due July 16 and questions due three days prior to closing. This is a total small business set-aside, WOSB-designated for 100 percent of the acquisition.

Place of performance is the Hookton Unit and Salmon Creek Unit in Loleta, California. Materials must consist of virgin quarried aggregate sourced locally within approximately 100 miles of the refuge; recycled and washed river rock are explicitly prohibited. All materials must meet Class-3 Aggregate Base construction standards. Offerors must submit the latest gradation analysis and test data demonstrating compliance with the Statement of Work standards before delivery, along with a statement acknowledging that locally sourced material will be supplied.

The base requirement includes 5,500 tons of road base gravel and 750 tons of trail gravel for the Hookton Unit levee road system. Option 1 adds 3,000 tons of road base gravel to the Salmon Creek Unit; Option 2 adds 1,000 tons of road base gravel to the Hookton Unit; Option 3 adds 100 tons of trail gravel to the Hookton Unit. The period of performance runs from September 1, 2026, to August 30, 2027, with a minimum of 75 percent of materials delivered between September 1 and October 1, 2026. Deliveries occur Monday through Sunday, 7:00 AM to 7:00 PM, excluding federal holidays, with 24-hour advance notice required.

The NAICS code is 212319 with a 550-employee size standard. Award goes to the responsible offeror with the lowest evaluated price meeting the minimum technical acceptability standard. Amendment 0002 (effective July 7) modifies submission timing for test data and adds the local-sourcing acknowledgment requirement; offerors must acknowledge receipt of both amendments by the proposal deadline.
