Thornton Tomasetti provided structural engineering services for the new Goodman Theatre, which features an 800-seat main theater and a 400-seat studio theater. Incorporated into the complex are portions of the building envelope and landmark facade of the Harris and Selwyn Theatres.
During construction of the underground subway in 1940, the Selwyn Theatre was underpinned by a series of concrete-encased girders. This underpinning provides the support for the Goodman studio theater, which is constructed within the shell of the existing theater. The main theater is concrete framed with the exception of the roof and gridiron that are steel.
Since the underground subway runs below the new theaters, the foundations of both theaters are supported on base isolators to minimize noise and vibrations from the trains.
