About Thornton Tomasetti, Inc.

Written by GovTribe AI ·

Thornton Tomasetti, Inc., a New York-based global engineering design and analysis firm with approximately 1,200 professional staff, operates as a prime contractor on full-and-open federal contracts across defense, civilian science, transportation, and infrastructure domains, with no SBA set-aside designations in its recent award footprint. The firm competes predominantly as a prime (90% of awards) and operates Weidlinger Associates, Inc. as a named subsidiary.

Thornton Tomasetti's capability portfolio centers on structural analysis, computational modeling, maritime survivability software development, and advanced engineering consulting. Representative prime work includes a $11.99 million cost-plus-fixed-fee delivery order from Naval Sea Systems Command under Seaport-NXG for Navy ship shock survivability and qualification analysis (placed in 2021, running through August 2026); a $20 million single-award indefinite delivery contract from the National Science Foundation's Directorate for Mathematical and Physical Sciences for SAC Peak emergency mercury removal engineering and remediation services (awarded March 2026, through March 2027); multiple Federal Railroad Administration definitive contracts for rail integrity research and defect characterization technology, including a $475,003 award for AI-based real-time defect characterization with physics-based remaining-life prediction (completed September 2024) and a $450,002 contract for upgraded detail fracture modeling (running through July 2026); and continued Maritime Survivability Library (MSL) software support under multiple Naval Sea Systems Command purchase orders, most recently a $250,000 award placed November 2025 for machine-learning algorithms and lethality-prediction enhancement work.

Customer concentration is heavily skewed toward defense. The Department of the Navy Naval Sea Systems Command dominates by dollar magnitude, anchoring $10.02 billion combined potential value across 40 awards (100% of top-customers-by-potential-value rankings). The Department of the Army ranks first by award count at 68 awards, followed by NAVSEA at 40, the Department of Homeland Security US Coast Guard at 12, the Department of the Navy at 12, and the Federal Railroad Administration at 9 awards worth $2.3 million. The top five customers account for 70% of total award count. NSF's Directorate for Mathematical and Physical Sciences ranks second by potential value at $23.7 million across three recent awards, a distant second to NAVSEA's dominance.

Thornton Tomasetti holds positions on Navy-managed and Army-managed indefinite delivery contracts. The top vehicle is Indefinite Delivery Contract N0016716D0007, with 27 task orders carrying $5.5 million combined potential value. Contracts DACA5192D0005, DTCGG198D3WK041, DACA5189D0005, and C2000031000 hold 12, 10, 9, and 8 task orders respectively. These vehicles support the firm's sustained delivery of ship shock analysis, maritime lethality tools, structural engineering, and rail research work.

Activity has been stable at 4 to 5 awards per year across the past five years (2022–2026), with six awards carrying ultimate completion dates in the next twenty-four months and combined potential value of $16.7 million facing recompete exposure. The combined potential value across all 201 awards (prime and sub) totals $10.06 billion, though only $67.3 million has been obligated to date (representing 1% of the potential value ceiling), reflecting the firm's positioning on large IDIQ vehicles with task-order-based spending.

In its subcontractor role, Thornton Tomasetti delivers structural engineering, design services, and technical analysis to prime contractors including Perkins Eastman Architects (structural consulting on Department of Energy consolidation and Veterans Administration benefits projects), Electric Boat Corporation (submarine development and testing support), Huntington Ingalls (UNDEX technologies and submarine engineering), Black & Veatch Special Projects (structural design and peer review for weapons facilities), Applied Research Associates (WMD analysis and planning tool development), and Tuskegee University (rail weld characterization and crack growth analysis under Federal Railroad Administration research programs). Across SCI-reportable service contracts, Thornton Tomasetti delivered 3 to 5 FTEs annually from 2022 through 2024, exclusively as a named subcontractor to other primes; SCI records account for 14 contracts above the $150,000 reporting threshold and represent a bounded subset of the firm's federal services activity, excluding goods, products, and classified work.
