Washington Headquarters Service Multiple Award Construction Contract II

The Washington Headquarters Service Multiple Award Construction Contract II (MACC II) is an indefinite-delivery, indefinite-quantity (IDIQ) contract vehicle providing design-build (DB) and design-bid-build (DBB) construction services for government facilities primarily in the National Capital Region. Established with a $150 million shared ceiling, the contract enables multiple small business contractors to perform construction, alteration, and repair services across facilities in the District of Columbia, Maryland, Virginia, and Adams County, Pennsylvania. The vehicle supports various federal agencies, with a focus on Department of Defense infrastructure and facility modernization projects.

Task orders under the MACC II consistently range from $1 million to $22 million, with completion periods typically spanning 18-36 months. Frequently winning prime contractors include HSU Builders (minority-owned), Signature Renovations LLC (HUBZone), Cherokee CRC LLC (tribally-owned), and Stampede Ventures, Inc. (Alaska Native Corporation-owned). Common project types include facility renovations, electrical system upgrades, generator replacements, mechanical system improvements, and infrastructure modernization efforts. Most task orders are firm fixed-price and do not utilize specific small business set-aside designations, though the prime contractors themselves often represent various small business categories. Performance locations are concentrated in Washington, Virginia, with significant work at high-security facilities like the Pentagon, Raven Rock Mountain Complex, and various Department of Defense administrative sites.
