About the company
Thornton Tomasetti, Inc., a New York-based global engineering design and structural analysis firm with approximately 1,200 professional staff, operates as a prime contractor on federal engineering, research, and remediation work across military and civilian agencies, with 90% of its recent award footprint in prime roles and no SBA set-aside participation. The vendor competes full-and-open across its portfolio and does not employ the subcontractor model for service delivery — SCI data show minimal sub-engagement and negligible prime-recorded invoicing, indicating most service work flows through direct labor.
Naval systems engineering and structural analysis dominate Thornton Tomasetti's federal profile. The Department of the Navy Naval Sea Systems Command accounts for 41 awards (100% of combined potential value at $10.02 billion), anchored by indefinite delivery contract N0016716D0007 with 27 task orders totaling $5.5 million in combined potential value. This represents a fundamental concentration cliff — the vendor's customer-by-potential-value ranking is functionally single-customer, with Naval Sea Systems Command's $10.02 billion dwarfing the second-place funder (National Science Foundation Directorate for Mathematical and Physical Sciences at $33.7 million). Within the NAICS and PSC coding, Thornton Tomasetti's work splits between Architect and Engineering–General (88 awards) and R&D–Defense Other (25 awards), with representative prime deliverables including Maritime Survivability Library (MSL) software development for damage prediction ($250,000 class purchase orders, recurring 2022–2026), ship shock survivability analysis, and naval weapons integration testing. The vendor also holds positions on indefinite delivery contracts DACA5192D0005 (12 task orders), DACA5189D0005 (9 task orders), and DTCGG198D3WK041 (10 task orders), with combined underlying scope in naval ship design, SSNX program engineering, and marine systems analysis.
Civil-sector and research work provides secondary volume. The Department of Transportation Federal Railroad Administration has placed nine awards ($2.3 million combined potential value) for rail integrity analysis and defect characterization technology, including AI-based real-time defect detection contracts ($475,003 completed; $474,969 ongoing through June 2028) and an upgraded fracture modeling contract ($450,002 with option year funding through July 2027). The National Science Foundation Directorate for Mathematical and Physical Sciences issued a $20 million single-award indefinite delivery contract in March 2026 for SAC Peak emergency mercury removal and structural remediation at Sunspot, New Mexico, with multiple delivery orders issued in 2026 (including a $3.071 million no-cost extension in July 2026 and a $9.999 million labor realignment order in September 2026). The Army, Coast Guard, and General Services Administration round out the active customer set; GSA's award ($105,999 for emergency structural column assessment at the SSA Altmeyer Building in Woodlawn, Maryland, completed December 2022) exemplifies the firm's facilities engineering and structural assessment capability.
Thornton Tomasetti subcontracts to prime defense and infrastructure firms, operating as a named subcontractor on engineering and technical service work. Recent sub positions include structural peer-review services under Black & Veatch Special Projects Corp. for weapons generation facility design at Dyess Air Force Base (June 2025), submarine UNDEX testing under Huntington Ingalls Inc. (February 2025), and structural engineering consulting on VA and federal building projects under Perkins Eastman Architects DPC (through 2023). Sub-work represents 10% of the award footprint; SCI data show Thornton Tomasetti appeared in 21 SCI records as a named subcontractor across FY2022–FY2025, delivering roughly 1.4 to 5 FTEs per fiscal year with no corresponding prime-recorded invoicing in the SCI dataset.
Activity is stable year over year (5 to 6 awards annually over the past four years) with modest recompete exposure — six awards (combined potential value $14.4 million) complete within the next twenty-four months. The vendor's subsidiary structure includes Weidlinger Associates, Inc., a historically distinct engineering consulting firm now operating under the Thornton Tomasetti corporate umbrella. Place of performance spans the vendor's New York headquarters (primary design and analysis work), a Westlake, Maryland facility supporting Naval Sea Systems Command and Naval Surface Warfare Center Carderock programs, and Sunspot, New Mexico (SAC Peak remediation operations).
