Gravel base material stockpile

The Bureau of Reclamation's Lower Colorado Region Multi-Species Conservation Program is seeking 7,000 tons of aggregate base course material for a stockpile at the Imperial National Wildlife Refuge, located approximately 45 minutes north of Yuma, Arizona. The solicitation (No. 140R3025Q0052) requires the material to meet specific gradation requirements, with a maximum size of 1 inch and a well-graded composition across multiple sieve sizes. Quotes will be evaluated based on price and delivery capabilities, with contractors required to deliver the material within 20 days of award, restricted to 7 AM to 4 PM Pacific time, Monday through Thursday. All questions must be submitted via email to Harris Abellon by May 23, 2025, and quotes are due by June 9, 2025, at 12:00 PM Pacific Time. The procurement will use the NAICS code 212321 for Construction Sand and Gravel Mining, with a small business size standard of 500 employees.

This solicitation is a 100% small business set-aside contract with a firm-fixed price purchase order anticipated. The delivery location has specific operational requirements, including a 15 mph speed limit to minimize wildlife disturbances and preferences for triaxle trucks over end dump trailers. Contractors will need to provide weight tickets for each delivery, and the refuge will handle material reshaping using their own equipment and staff. The project site has some logistical challenges, including turn radius limitations that may impact delivery vehicle selection. While the original solicitation initially requested 9,000 tons, the quantity was amended to 7,000 tons, with the government expecting to award the contract within 5-7 days of quote receipt. Delivery will be made directly to the stockpile area at the Imperial National Wildlife Refuge, with careful maneuvering required during the delivery process.
