Worldwide Environmental Engineering Services

The U.S. Department of State, through its Bureau of Overseas Buildings Operations, is soliciting proposals for a five-year Firm-Fixed-Price Indefinite Delivery/Indefinite Quantity contract to provide comprehensive environmental engineering services at U.S. diplomatic facilities worldwide. This contract, identified as 19AQMM26R0323, is a total small business set-aside under NAICS code 541330 with an estimated total value of $4.5 million, covering a base year and four one-year options, each worth $900,000. The contract requires a qualified environmental engineering firm—either as a prime or joint venture—with the technical competence to deliver asbestos and lead-based paint inspections, hazardous materials assessments, indoor air quality investigations, mold and radon testing, environmental site assessments, and remediation oversight in compliance with EPA AHERA, DOD 5220.22-M, and other federal and international standards. All work will be performed globally, including in high-threat locations, with administrative coordination based in Grassy Creek, Virginia, and oversight managed from Washington, DC. Proposals must be submitted electronically via SAM.gov by August 17, 2026, under a three-stage evaluation process mandated by the Brooks Act. The first stage assesses the technical qualifications of the lead team and core personnel, including certifications such as Certified Industrial Hygienist, Certified Hazardous Materials Manager, and Certified Safety Professional. The second stage evaluates the proposed team structure, project management approach, and past performance on similar projects. Only the most highly qualified offerors will be invited to submit pricing in the third stage, where cost becomes a factor in a best-value trade-off, not the primary determinant. A critical requirement is possession of, or eligibility to obtain, a DCSA Top Secret Facility Clearance and an approved classified information system; foreign ownership, control, or influence is prohibited unless fully mitigated under DCSA-approved protocols. Offerors must be U.S.-organized entities with active SAM.gov registrations and valid Unique Entity IDs. The contract will commence on May 16, 2027, and conclude on May 15, 2032, with acceptance of deliverables occurring at the site of performance, including overseas diplomatic posts and domestic OBO facilities.
