The contract requires the supply of virgin quarried aggregate gravel for the Humboldt Bay National Wildlife Refuge, specifying two types: 1.5-inch minus road base gravel with fines and 3/8-inch minus trail gravel with fines, both of which must be newly mined from local geological deposits within approximately 100 miles; recycled, washed, or rounded river rock is strictly prohibited. The base requirement includes 5,500 tons of the 1.5-inch material and 750 tons of the 3/8-inch material to be delivered to the Hookton Unit, with an optional additional 3,000 tons of the 1.5-inch material for delivery to the Salmon Creek Unit levee road system. All materials must be tailgate spread on-site as directed by refuge personnel, who will provide 24-hour advance notice for deliveries and confirm receipt with a signed bill of lading.

Pricing must include all costs—material, delivery, placement, labor, equipment, overhead, and profit—quoted per ton, with no separate line items unless specified. Technical acceptability, including material compliance and past performance, serves as a pass/fail gate, and award will go to the lowest-priced responsive offeror meeting all technical requirements, with no tradeoffs permitted. The solicitation is a Total Small Business Set-Aside under NAICS Code 212319, and offerors must be registered in SAM, certified as small businesses, and current on all required representations.
