Managed by the Bureau of Land Management, the project is set aside for total small businesses under NAICS 237990.

The project must be substantially completed by December 10, 2027, or within 350 calendar days of the notice to proceed. The contract includes strict environmental and operational constraints, most notably an annual construction shutdown from March 15 to July 15 to protect migratory birds and sage grouse.

Award will be based on a Best Value Tradeoff process evaluating experience, schedule, past performance, and pricing. To maintain small business integrity, the prime contractor must self-perform at least 15 percent of the total contract cost, excluding materials. Proposals must be submitted in four distinct volumes via email, with technical and past performance evaluations serving as primary non-price risk factors.
