56--CA - Humboldt Bay NWR - Gravel

The contract solicits the delivery of virgin quarried aggregate gravel for use in road and trail construction at Humboldt Bay National Wildlife Refuge, specifically in the Hookton and Salmon Creek Units. Two material types are required: 1.5-inch minus road base gravel with fines and 3/8-inch minus trail gravel with fines, all sourced exclusively from newly mined, local geological deposits within approximately 100 miles; recycled or washed river rock is strictly prohibited. Offerors must submit current gradation analysis and test data demonstrating compliance with the Statement of Work (SOW) alongside their pricing. The solicitation is a Total Small Business Set-Aside under FAR 19.5, with NAICS code 212319, and will be awarded using the Lowest Price Technically Acceptable (LPTA) method, meaning technical acceptability is the primary factor and must be met before price is considered. The contract is a Firm Fixed Price Supply contract with a performance period from September 1, 2026, to August 30, 2027, requiring at least 75% of the total material to be delivered between September 1 and October 1, 2026. Deliveries are to be tailgate-spread at designated locations within the refuge, and acceptance occurs on-site upon physical inspection by the Government’s Principal Technical Coordinator, who will verify compliance with specifications and review documentation. All materials must be tested and documented prior to delivery, and rejected if they fail to conform, including the use of unauthorized materials. Payment must be processed electronically via the Invoice Processing Platform (IPP), and contractors are required to enroll in IPP through the Federal Reserve Bank of St. Louis. The contract includes numerous FAR clauses related to subcontracting restrictions, whistleblower protections, supply chain security, prohibitions on certain foreign-sourced equipment and software (including provisions targeting Kaspersky, ByteDance, and other covered entities), and compliance with labor standards. Offerors must certify their small business status, provide their Unique Entity Identifier and CAGE code, and disclose ownership structures and any involvement with prohibited entities. Proposals must be submitted electronically to Robert_Sung@ios.doi.gov with the solicitation number in the subject line by the July 15, 2026 deadline, and hard copies are not accepted. The Government will designate a Contracting Officer’s Representative at award to oversee technical compliance.
