Weston-Techlaw JV LLC

Weston-Techlaw JV LLC, a for-profit limited liability company joint venture headquartered in Chantilly, Virginia, operates as a prime contractor delivering environmental remediation, site investigation, and Superfund support services to the Environmental Protection Agency on a full-and-open basis, with no SBA set-aside designations across its federal footprint.

The joint venture holds a single dominant parent vehicle: the Environmental Response Team (ERT) indefinite delivery contract 68HE0321D0001, a $105.6 million single-award IDC with the EPA's Office of Land and Emergency Management running through July 2027. Weston-Techlaw issued 90 task orders under this vehicle valued at $53.1 million combined potential value. Representative task orders exemplify the scope: a $2.25 million hydrogeological assessment and conceptual site model integration at the Selma Wood Treating Company site in California (awarded September 2023, invoicing $346 thousand in FY2024 across 0.6 FTEs); a $3.69 million residential support engagement at the Iron King Mine Superfund site in Arizona (awarded August 2023, invoicing $691 thousand in FY2024 across 2.9 FTEs); and a $21.3 million Core Response Team support contract (awarded August 2022, fully funding Weston-Techlaw's emergency response operational infrastructure through July 2027). A secondary $1.07 million delivery order for Southern California Wildfires environmental emergency response (February 2025) demonstrates the vendor's active engagement in crisis-response site assessment and remediation prioritization. All work operates on time-and-materials or firm fixed-price delivery orders under the master ERT contract; no set-aside was applied to any award in the source data.

Customer concentration is absolute and deliberate. The EPA Office of Land and Emergency Management (the funding office for the ERT master contract) accounts for 72 of 91 awards (79% by count) and $156.5 million of $158.7 million combined potential value (99% of dollars). The remaining five EPA regional offices (Regions 1, 2, 3, 6, and 9) account for 15 awards and $1.9 million combined potential value. No other federal agencies appear in Weston-Techlaw's award portfolio; EPA is the sole customer. This customer concentration reflects the vendor's position as the single awardee on the ERT master contract and the lack of diversified pursuit.

Activity trajectory shows expansion followed by stabilization. Awards per year climbed from 19 in 2022 to a peak of 34 in 2023, then declined to 14 in 2024 and 14 in 2025, with 8 awards in the first six months of 2026. Combined potential value growth has been dampened by the shift toward smaller, site-specific task orders; the FY2023 spike in award count did not correspond to equivalent dollar growth, suggesting a transition from larger bundled scopes to granular site investigations. Recompete exposure is material: 44 awards (combined potential value $44.7 million) carry ultimate completion dates within the next twenty-four months, representing 28% of the combined potential value across the full portfolio. The master ERT contract itself extends through July 2027, but task order-level recompete activity will drive near-term revenue volatility.

On SCI-reportable service contracts, Weston-Techlaw invoiced $13.9 million across FY2022–FY2024, with sharp year-over-year growth: $456 thousand in FY2022 (2.6 FTEs), $4.2 million in FY2023 (3.3 FTEs), and $9.2 million in FY2024 (11.8 FTEs). The 3.6-fold increase in FTEs from FY2023 to FY2024 reflects scaling of active site engagement and sustained remediation work; growth continued into FY2024 despite flat award count, indicating deeper execution across the existing task-order portfolio. Government-paid hourly rates span a wide range reflecting mixed labor categories: the median rate ran $114.43 per hour, with 10th-percentile labor at $83.59 per hour and 90th-percentile specialized or supervisory roles at $326.24 per hour. SCI data capture remains limited to invoiced service contracts above the $150,000 threshold and excludes goods, products, and non-federal work; these figures represent a partial slice of the vendor's federal services footprint and a smaller subset of total enterprise revenue.

Teaming posture reveals a predominantly self-performed model. Across SCI-reportable prime contracts, subcontractors performed only 2 percent of total contractor hours on average, with three named subcontractors reported across the SCI dataset. Named subcontractors appearing in the source include Betts Drilling, Inc. (a self-certified small disadvantaged business engaged for drilling services on the Captain Jack Mine Superfund site vadose zone carbon effectiveness order, October 2024), Environmental Data Services, LIMITED (a self-certified small disadvantaged and economically disadvantaged women-owned small business engaged for data validation on the Iron King Mine site, July 2025), Pacific Mobile Structures, Inc. (a small business subcontracted for architectural planning and modular building design on EPA facility relocation and trailer decommissioning, FY2024), and AST Environmental Inc. (engaged for remedial design characterization on the Alaric Superfund site response engineering order, August 2025). Integral Consulting Inc. was subcontracted for water quality monitoring and modeling on the Lake Allegan remediation (May 2025). The low sub-hours share and named-sub scarcity indicate Weston-Techlaw builds and executes its own delivery teams for environmental investigation and remediation fieldwork, with selective subcontracting to fill specialized technical gaps (diving operations, drilling, data systems) rather than outsourcing core environmental science or project management.

All 91 awards are categorized under Environmental Consulting Services NAICS with split PSC distribution: 63 awards under Environmental Systems Protection – Environmental Consulting and Legal Support and 28 under Environmental Systems Protection – Environmental Remediation. Place of performance spans multiple EPA regions and contaminated sites nationwide, with administrative oversight coordinated from Chantilly, Virginia. The vendor operates as a pure EPA services provider with no diversified agency exposure or teaming relationships to other large prime contractors; competitive entry into federal environmental remediation work outside the EPA would require new vehicle capture or subcontracting to existing EPA primes.
