AOC MACC Onboarding

The Architect of the Capitol (AOC) is seeking to onboard contractors to an existing Multiple Award Construction Contract (MACC) Indefinite-Delivery Indefinite-Quantity (IDIQ) contract for construction services across the United States Capitol Complex and outlying facilities. The solicitation will use a two-step evaluation process to select approximately five contractors capable of performing maintenance, repair, alteration, mechanical, electrical, and historical preservation work within the Capitol Complex and facilities in Washington DC, Virginia, and Maryland. Contractors must demonstrate specialized construction management experience, particularly with historic buildings, and provide key personnel with extensive industry experience. The evaluation will assess factors including specialized construction experience, key personnel qualifications, past performance, management plans, quality control programs, and safety plans, with technical factors being significantly more important than pricing. Step 1 proposals are due January 9, 2025, with Step 2 proposals due May 1, 2025, and final awards anticipated in August 2025.

The contract has no specific small business set-aside and is open to full and open competition, with current incumbent contractors including Balfour Beatty, Christman, Gilbane, Grimberg, Hensel Phelps, Kiewit, and Walsh Federal. The MACC has a total aggregate maximum value of $250 million, with individual task orders ranging from $1 million to $50 million and a guaranteed minimum of $1,000 per contractor. The contract will cover Option Years 4-7 of the existing MACC, spanning from March 1, 2025 to September 1, 2029. Task orders will be issued for various project types including design-bid-build and design-build, with most projects expected to be under $10 million. The primary place of performance is Washington, DC 20515, encompassing over 17.4 million square feet of building space and 530 acres of land, including the U.S. Capitol, House and Senate Office Buildings, Library of Congress, Supreme Court, and other critical government facilities.
