About this opportunity
The Department of the Air Force Global Strike Command seeks award of a Horizontal Construction Multiple Award Contract (MAC) for heavy civil construction projects at Malmstrom Air Force Base, Montana, with proposals due August 6, 2026. The procurement is 100 percent small business set-aside with a mandatory site visit on July 9, 2026 at 9:00 a.m. MDT. Questions are due July 16, 2026.
Place of performance is Malmstrom AFB, MT. The contract vehicle is an indefinite-quantity MAC with an initial five-year ordering period and optional two-year extension. The total aggregate maximum contract value shall not exceed $25 million, with a guaranteed minimum of $500 satisfied by Post-Award Conference attendance. Individual task orders range from $2,000 to $5 million. The Government targets award of eight firm-fixed-price contracts but reserves the right to award more or fewer. The seed project is "Repair North/South Base Water System, Phase 2," encompassing approximately 3,978 linear feet of water main replacement across multiple base locations, with performance of 180 calendar days after Notice to Proceed for the base item and 90 days for the optional item. Liquidated damages are $462.36 per calendar day for the seed project.

Contractors must demonstrate past performance on design-build or design-bid-build heavy civil construction projects valued $100,000 to $3 million completed within six years, and submit three to five references. Evaluation uses best-value source selection with Past Performance and Combined Technical/Risk rated significantly more important than Price. Proposals receiving Combined Technical/Risk below Acceptable (Green) or Past Performance below Neutral Confidence are ineligible. Proposals require Volume I (Project Management Plan and Gantt Chart, 6 pages maximum), Volume II (Past Performance, 40 pages maximum), and Volume III (Price/Required Documentation). A bid bond of 20 percent of bid price or $1 million, whichever is less, and proof of $5 million bonding capacity are required. Performance and payment bonds at 100 percent of contract price are due within 10 calendar days of award. Contractors must maintain 75 percent annual proposal participation on Fair Opportunity Proposal Requests or face off-ramp procedures. All personnel require federal installation access via Contractor Entry Authorization List by July 1, 2026. Prevailing wage determination MT20260066 applies.
