C.j. Seto Support Services, LLC

C.J. Seto Support Services, LLC, a service-disabled veteran-owned, minority-owned small business based in Ventura, California, operates as a prime contractor (96% of recent awards) delivering environmental sampling, hazardous materials inspection, industrial hygiene, and facility contamination assessment services to defense and civilian agencies. The vendor holds multiple federal certifications including SDVOSB, Asian-Pacific American Owned, and DOT Certified Disadvantaged Business Enterprise status, and competes predominantly on full-and-open or non-set-aside task orders, with some work flowing through SDVOSB-reserved vehicles.

C.J. Seto's capability portfolio centers on environmental field services: asbestos and lead-based paint sampling, building demolition and renovation environmental surveys, water and pool sampling, chemical inventory management, and baseline environmental assessments at federal facilities. Recent prime work includes a $262.5 million delivery order from Naval Sea Systems Command for FY23 asbestos baseline samplings at Naval Support Activity Crane, Indiana (July 2023); a $225.2 million Army delivery order for environmental sampling and CAAA asbestos field survey work at Crane (March 2025); a $3.1 million VA delivery order for chemical inventory filing in Lemay Township, Missouri (December 2021); and a $615.7 million Coast Guard delivery order for hazardous material logistics services at USCG Base Honolulu through March 2028 (April 2023). The vendor also delivers industrial hygienist services under a GSA Multiple Award Schedule BPA with the Chemical Safety and Hazard Investigation Board ($300,000 ceiling through September 2029).

Customer concentration is heavily weighted to Navy and Army programs. The top five funding agencies account for 71% of recent awards by count. Naval Facilities Engineering Command anchors volume with 126 awards (combined potential value $55.3 million), while Naval Sea Systems Command, despite only 30 awards, carries the dollar load at $82.62 billion combined potential value — a stark divergence driven by a small number of very large delivery orders under Navy indefinite-delivery contracts. The Department of Veterans Affairs (22 awards, $1.7 million), the Army (17 awards, $661,000), and Defense Logistics Agency (13 awards, $3.1 million) round out the active set. When ranked by potential value, GSA Federal Acquisition Service ($5.01 billion across two awards) and VA Office of Construction and Facilities Management ($900 million across six awards) become material players, reflecting C.J. Seto's seat on large VA environmental consulting IDIQs.

C.J. Seto holds three recently awarded single-award indefinite-delivery contracts with the VA Office of Construction and Facilities Management, each with a $300 million ceiling and running through March 2031 (awarded September 23, 2025). These contracts cover environmental, historic preservation, and sustainability consulting including hazardous materials inspection, environmental contamination analysis, endangered species management, and environmental law compliance at VA facilities nationwide under NAICS 541620. The vendor also places significant task-order volume under Navy IDIQs: Indefinite Delivery Contract N6247312D4421 (69 task orders, $7.9 million combined potential), N3943013D1203 (51 task orders, $17 million combined potential), and N4008520D0124 (48 task orders, $1.8 million combined potential). C.J. Seto maintains a GSA Multiple Award Schedule presence with 64 task orders across $34.3 million in combined potential value, anchored by the CHSB BPA and various other federal agency BPA calls.

Activity has remained moderate and stable across the past five years — ranging from 5 to 13 awards annually — with 11 awards placed in 2025 and 5 so far in 2026 (as of late September). The award pipeline faces a recompete cliff: six awards with potential value totaling $25.6 million are scheduled for ultimate completion within the next twenty-four months, creating near-term recompete exposure primarily in Navy and Army environmental sampling task orders at Crane and other installations.

SCI-reported invoiced revenue from federal service contracts above the $150,000 threshold totaled $14.1 million across FY2022–FY2025. Invoicing peaked in FY2024 at $7.2 million across 31.4 FTEs, then moderated to $3.7 million across 25.4 FTEs in FY2025. Government-paid median hourly rates on SCI-reportable prime work ran around $89.26/hr, with senior labor pricing reaching into the $4,600/hr range and junior rates at roughly $61/hr. Across SCI-reportable prime contracts, C.J. Seto self-performed approximately 97% of contractor hours, naming only two subcontractors in the dataset and averaging just 3% sub-hours share — the vendor builds its own delivery teams rather than leaning on subcontractor networks.

In its subcontractor role, C.J. Seto delivers ground-based strategic deterrent engineering and manufacturing development support to Northrop Grumman (one named sub award, December 2025), representing the vendor's only notable prime-contractor sub relationship in the recent award record. The vast bulk of C.J. Seto's business operates as a prime under Navy and VA environmental consulting vehicles, with minimal downstream teaming.
