About this opportunity
The Department of the Army is seeking mission support services for the West Desert Test Center (WDTC) located at Dugway Proving Ground in Utah through a comprehensive solicitation. The contract will provide non-personal services supporting developmental and operational testing across multiple specialized divisions, including Chemical Test, Special Programs, Data Sciences, Test Support, and BioTesting Dugway. Key contract requirements include supporting chemical, biological, radiological, nuclear, and explosive (CBRNE) testing, providing highly specialized scientific and technical personnel, and maintaining sophisticated testing equipment across complex environments. The government will evaluate proposals based on technical capability, past performance, and cost, with non-cost factors being significantly more important than price. Proposals are due by 5:00 PM EDT on April 29, 2025, with potential offerors required to submit detailed technical and cost proposals addressing two specific scenarios.
The solicitation is a total small business set-aside with a base period of 4 years and 10 months from October 23, 2025, through October 22, 2030, and an optional two-year extension possible through October 22, 2032. The contract includes a two-month phase-in period and will support mission-critical testing activities involving chemical warfare agents, biological agents, simulants, and specialized test environments. While specific award values are not definitively stated, historical labor hours data indicates approximately 899,389 total hours across 48 labor categories from 2022-2024. The performance location will be Dugway Proving Ground in Utah, with potential additional testing locations in Wyoming. Personnel will be required to obtain and maintain specific security clearances, with the contract supporting testing for the Department of Defense, other federal agencies, and international partners.
