Weidlinger provided substructure rehab and redecking design for seven steel approach structures, ramp structures, and approach roadways on brick arches at the Brooklyn Bridge;structural and blast engineering for the WTC transportation hub; value engineering design for two access shafts of the Harlem River Tunnel to accommodate construction of a horseshoe-shaped utility tunnel; and a realm of services for a number of bridges such as the Manhattan Bridge, Queensboro Bridge, Tappan Zee, and George Washington Bridge.

Thornton Tomasetti will benefit from Weidlinger practices that add technical depth, new geographic presence and market advantage to the company's existing practices and markets. In addition, Weidlinger brings long-standing ties as a government contractor in the US and UK. Meanwhile, Weidlinger benefits from significantly expanding its geographic reach, market access and project diversity, as well as access to a robust platform for innovation and growth.

Thomas Scarangello continues as chairman & CEO of the combined companies, with Raymond Daddazio joining Robert DeScenza as co-president. Daddazio and two other Weidlinger board members, Grant McCullagh and Tod Rittenhouse, join the 11-person Thornton Tomasetti board of directors.

“Combining our firms brings together two highly respected and recognized talent pools, creating significantly greater potential for growth and innovation than either firm could achieve alone,” says Scarangello. “Both of our cultures have a 'one firm' approach, bringing the best qualified team to bear on any challenge presented by any client. Our more diverse merged expertise allows us to address a wider range of client needs, while offering enhanced breadth and depth of services and extended geographic reach.”

Adds Daddazio, “Just as important as our complementary suite of services and geographic footprints is our compatible cultures. While no two firms are exactly alike, ours bear many similarities – including the drive for innovation, long-standing entrepreneurial spirits, and shared values in philanthropy, employee enrichment, embracing challenges and a desire to make lasting contributions. We're also different enough in ways that our combination will inspire us to think and work in new and exciting ways.”
