About GSE Inc.
GSE Inc., a SBA-certified women-owned small business headquartered in Trinity, Alabama, delivers environmental sampling, occupational health services, site remediation, and engineering survey support to federal agencies as a prime contractor (91% of recent awards) and subcontractor. GSE competes predominantly under the woman-owned small business set-aside across its prime footprint; all ten visible prime awards carry either woman-owned or no set-aside designation, with woman-owned set-asides dominating the portfolio.
GSE's capability portfolio centers on environmental and occupational health services grounded in three concrete domains: occupational health screening and medical informatics for NASA personnel; environmental sampling and site remediation under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA); and engineering surveying for military construction and facilities projects. Representative prime work includes nine BPA calls totaling $11.2 million with NASA Kennedy Space Center under the NASA Occupational Health Contract II on the GSA Multiple Award Schedule, covering medical screenings, testing, consultation, and medical informatics support through September 2026; a $606 thousand purchase order from the Army Corps of Engineers Engineering Support Center Huntsville for survey work at Sheppard Air Force Base (September 2023–September 2024); and a $72 thousand woman-owned small business set-aside definitive contract from the Department of Defense Engineering and Support Center for environmental sampling of Building 54 at the Veterans Administration Medical Research Laboratory in Palo Alto, California (completed August 2026).
Customer concentration is dominated by NASA Marshall Space Flight Center and Kennedy Space Center. NASA Marshall drives both volume and dollars — 50 awards with $56.8 million combined potential value — while NASA Kennedy carries 17 awards valued at $31.9 million. The Army Corps of Engineers Engineering Support Center Huntsville anchors the third position with 71 awards but at a lower dollar magnitude ($9.9 million combined potential value), signaling a mix of high-volume, lower-value survey and project support contracts. These three agencies account for roughly 87% of recent awards. GSA Federal Acquisition Service appears as an outlier by potential value — one award of $20.1 million — reflecting GSE's seat on the Multiple Award Schedule. The Department of Homeland Security US Coast Guard and EPA Region 3 round out the active set with smaller portfolios.
GSE places task orders under three primary vehicles: the NASA Indefinite Delivery Contract NNM11AA25C (43 task orders, $6 million combined potential value), the Army Corps of Engineers Indefinite Delivery Contract W912DY11D0026 (41 task orders, $4.1 million combined potential value), and the GSA Multiple Award Schedule (19 task orders, $38.8 million combined potential value). A Blanket Purchase Agreement NNK15OL20Z carries 7 NASA task orders valued at $8.6 million, and EPA's Remedial Acquisition Framework for Design and Engineering Services supports 3 tasks.
Recent activity shows flat to declining volume — one award in 2022, six awards each in 2023, 2024, and 2025, and four awards to date in 2026 — with only two awards facing recompete completion in the next twenty-four months (combined potential value $1.8 million), reflecting a mature but stable contract portfolio. In its subcontractor role, GSE delivers drilling services, site preparation, remediation services, and CERCLA support under primes including Ch2M Hill Inc., Jacobs Geosyntec A Joint Venture, EQ & CH Remediation, Arcadis U.S. Inc., AECOM Technical Services, and Amentum Technology Inc., with work concentrated on site restoration and feasibility study technical support.
