Thornton Tomasetti Wins $10 Million Brooklyn Bridge Cable Hardening Design Contract

Thornton Tomasetti Inc. has won a U.S. Army Corps of Engineers contract worth up to $9.9 million to prepare construction plans and specifications and provide construction-phase support for the Brooklyn Bridge Cable Hardening Project. The New York-based firm received a single-award, firm-fixed-price architect-engineer contract under which the Corps will issue orders for the work. The contract has an estimated completion date of Sept. 29, 2031.

Brooklyn Bridge Cable Hardening Project Details

Thornton Tomasetti will develop the plans and specifications needed for construction of the cable-hardening project. The award is for design and support services, rather than construction of the upgrades themselves.

The company will also provide support during the construction phase. The Corps will determine work locations and the work assigned to the firm through individual orders. The Sept. 29, 2031, date is the estimated completion date for this services contract, not a stated deadline for completing construction.

Award and Contractor Background

The Corps solicited bids online and received one. The award comes amid broader planning for work on the historic bridge: a New York City Council analysis of the transportation department’s preliminary capital plan lists $843.3 million in planned Brooklyn Bridge rehabilitation commitments for fiscal 2027, with the bulk intended for hardening and security upgrades. That figure is a proposed city capital commitment, not the value of Thornton Tomasetti’s federal contract.

Bridge work has addressed the cable system before. The city’s 2019 bridge condition report records cable-anchorage rehabilitation and short suspender-rod replacement under a 1988 contract, followed by replacement of suspenders and stay cables and rewrapping of the main cables under a 1991 contract. More recently, the city described a roughly $300 million Brooklyn Bridge rehabilitation covering approaches, towers, foundations and building systems; that announcement did not identify cable hardening as part of the work.

This award was disclosed by the DoW in its daily press release. Additional contract details will be available on HigherGov in approximately 90 days under W912DS27DA001 after the contract is formally disclosed by the government.
