This Request for Proposal (RFP 140P8125Q0032) seeks a contractor to provide approximately 10,616 cubic yards of aggregate road base material that meets specific technical specifications detailed in the Statement of Work. Contractors must submit comprehensive administrative materials including a Safety & Accident Prevention Plan and sieve analysis with Plasticity Index, and ensure all drivers complete desert tortoise training to comply with strict environmental protection requirements. The government will evaluate offers based on both price and technical factors, specifically requiring a product submittal that meets or exceeds the minimum salient characteristics outlined in the scope of work. Offerors must submit their quotes via email to the contracting specialist, and the anticipated contract award date is late September 2025.

This procurement is designated as a 100% small business set-aside under NAICS code 212321 (Construction Sand and Gravel Mining) with a size standard of 500 employees. The government intends to award a single firm fixed-price contract with deliveries scheduled between October 15, 2025 and February 15, 2026, specifically timed to avoid peak desert tortoise activity outside these dates. All aggregate must be delivered to a mixing table on Ivanpah Road during specified work hours of Monday through Friday, 7:00 AM to 5:00 PM, allowing National Park Service equipment operators to stockpile the material. The contract performance period runs from September 25, 2025 to February 15, 2026, with the contract administered by NPS Pacific West Region Lake Mead office in Boulder City, Nevada. The Park Facility Manager overseeing this project is Jeremy Petruncio, located in Barstow, California, and the solicitation response deadline is August 22, 2025.
