This is a total small-business set-aside Job Order Contract (JOC) for sustainability, repair, maintenance, and minor construction work at McAlester Army Ammunition Plant (MCAAP) in support of Directorate of Public Works. The contract consists of a one-year base period plus four one-year option periods, with individual firm-fixed-price task orders having a $5,000 minimum and up to $19,800,000 per period, and a total maximum value of $99,000,000. Pricing is based on a single coefficient applied to 2026 RSMeans unit price books for future task orders, with a sample task order for a 50’x100’x18’ red iron storage facility used for evaluation. Award will be best value, with non-price factors, primarily past performance, significantly more important than price, and offerors must show relevant completed government projects ranging from $100,000 to $3,000,000. Task orders require bonding over $35,000, insurance, and may include liquidated damages for delay, with work performed under normal and other-than-normal hours.
