DOS Domestic Light Construction Multiple Award IDIQ Requirement

The Department of State Office of Acquisition Management is soliciting proposals for Domestic Light Design/Build and Design-Bid-Build Construction Services through an Indefinite Delivery/Indefinite Quantity (IDIQ) multiple-award contract. The contract will support construction, repair, and renovation projects at federal installations across the United States, with estimated task order values ranging from $2,000 to $3 million and average project durations between six months and two years. Offerors must be small businesses registered in SAM.gov under NAICS code 236220 (Commercial and Institutional Building Construction) and must maintain a minimum bonding capacity of $5 million per single project while self-performing at least 15 percent of contract costs. Evaluation will be conducted using a best-value tradeoff methodology based on four technical factors: Past Performance and Financial Capability, Project Understanding, Execution Approach and Methodologies, and Security Clearance Capability, with past performance weighted more heavily than price. Critical deadline dates include January 27, 2026 for submission of questions, and February 20, 2026 at 4:00 PM ET for proposal receipt, with three amendments issued on January 22, February 4, and February 11, 2026 to clarify requirements and extend the original February 11 deadline.

This solicitation is designated as a Total Small Business set-aside with no incumbent contractors, as this is a new requirement. The Government anticipates awarding three to five IDIQs per geographic zone across four regions: Zone 1 (Blackstone, Virginia), Zone 2 (Charleston, South Carolina), Zone 3 (Denver, Colorado), and the National Capital Region (Washington, D.C.). Each IDIQ carries a $50 million ceiling value with a minimum guarantee of $10,000, and the contract will run for a one-year base period beginning January 26, 2026, through January 25, 2027, plus four optional one-year extension periods extending through January 25, 2031. Offerors may submit proposals for only one geographic zone and must provide fully burdened labor rates for all specified labor categories, with technical proposals limited to 20 pages (excluding resumes, bonding letters, and financial reports). Work will be performed at various Department of State federal facilities across the United States, with primary concentrations at facilities in Arlington, Virginia and Blackstone, Virginia, as well as other locations identified in the DOS facilities inventory.
