Tdi-Brooks International Inc.

Tdi-Brooks International Inc., a for-profit analytical chemistry and environmental monitoring firm based in College Station, Texas, operates as a prime contractor providing laboratory analysis, sediment analysis, mussel contaminant analysis, and coastal ocean science support to federal agencies on a full-and-open, non-set-aside basis. The vendor competes predominantly as a prime (99% of awards) and does not rely on subcontracting for delivery.

Tdi-Brooks' customer base is heavily concentrated in civilian environmental and natural-resource agencies. The National Oceanic and Atmospheric Administration dominates the relationship: 71 awards worth $56.8 million combined potential value represent 59% of the vendor's award count and 58% of combined potential value. The Department of the Interior's Bureau of Ocean Energy Management, Fish and Wildlife Service Region 9, and Fish and Wildlife Service proper round out the top four funding agencies, collectively anchoring another $30.5 million in combined potential value across 44 awards. Together, these three Interior sub-agencies and NOAA account for 93% of Tdi-Brooks' combined potential value, signaling acute customer concentration in coastal science and fisheries research.

Tdi-Brooks holds three active parent vehicles. The GSA Multiple Award Schedule carries 54 task orders worth $23.8 million combined potential value and serves as the primary ordering mechanism for NOAA delivery orders. The vendor also manages two single-award IDIQs: a $9.999 million Indefinite Delivery Contract with NOAA for analytical chemistry services supporting the National Centers for Coastal Ocean Science (Mussel Watch, Bioeffects Assessment, and Special Studies programs), awarded September 30, 2024, and a $5 million Blanket Purchase Agreement with the Department of the Interior Fish and Wildlife Service Region 1 for organic laboratory supplies, awarded September 22, 2023. Legacy indefinite delivery contracts continue to generate task orders — INF982108D106 (47 task orders, $732 thousand) and 982103D045 (41 task orders, $228 thousand) — reflecting sustained NOAA and Interior engagement over time. Recent representative work includes a $277,858 delivery order from NOAA (July 2026) for laboratory analyses supporting coastal ocean science research, a $218,190 firm-fixed-price purchase order from the USGS Southeast Ecological Science Center (June 2023) for sediment analysis, and a $94,136 delivery order from NOAA (August 2025) for laboratory analyses supporting the National Park Services Alaska Network.

Activity has slowed from a peak of eight awards in 2023 to one each in 2025 and 2026 as of the source snapshot (mid-July 2026). Ten awards with ultimate completion dates in the next twenty-four months carry $1.4 million in combined potential value and face recompete risk. The vendor's award footprint spans 202 total prime and sub awards dating to 1999, with combined potential value of $97.3 million and combined dollars obligated of $29.3 million (30% of potential). Work is performed at the contractor's College Station, Texas facility. NAICS coding reflects the core business: Testing Laboratories and Services dominates 161 awards; Environmental Consulting Services and All Other Professional, Scientific, and Technical Services appear in five and four awards respectively. PSC coding confirms the analytical focus: Special Studies/Analysis–Chemical/Biological accounts for 122 awards, with R&D General Science/Technology (Environmental Sciences) in eighteen awards.

Service Contract Inventory data captures only $21 thousand in SCI-reportable invoiced revenue across FY2022–FY2023 (three prime records, zero sub records), reflecting the fact that Tdi-Brooks' federal work streams consist predominantly of goods purchases, purchase orders, and delivery orders below or outside SCI reporting thresholds, rather than labor-centric service contracts. The vendor subcontracts to Applied Physical Sciences Corp on Department of Defense DARPA research vessel services and charter work (two sub awards, August 2024 and March 2024) and appears as a sub-recipient to the University of Texas at Austin on a Department of Energy NETL grant for offshore carbon storage research in the Gulf of Mexico (February 2024). Neither subcontracting nor grant sub-award activity is material to the overall footprint.
