Completed in 1939, Fallingwater is comprised of a series of concrete cantilever “trays” 30-ft. above a waterfall. Previous efforts failed to permanently address excessive defl ections of the cantilever and repair the cracks. After a thorough design review, the owner and engineer selected an external post-tensioning solution for its durability, aesthetics and structural unobtrusiveness.

That is why Perini Building Company -- the largest builder of hotels and casinos in the United States and general contractor for new construction and renovation of the Resorts International Casino in Atlantic City -- and the owner of Resorts Casino looked to create a team that could bring together both engineering and construction expertise for a critical path concrete repair and strengthening project. They assembled a team that included Structural Group -- one of the nation’s leading specialty contractors in concrete repair -- and Lochsa Engineering -- one of the premier design groups for casino construction and renovations.
