225 West Washington Office Tower

During the final construction phase of this 28-story high-rise office tower, questions arose regarding the adequacy of some granite-clad precast concrete panel connections and the surface damage to the granite and exposed concrete surfaces. RRJ investigated the cladding lateral and gravity connections and inspected the exterior cladding surface conditions. Corrective repairs to the connections were designed with installations inspected by RRJ. Laboratory testing was undertaken to develop and determine the granite and concrete surface repair techniques and procedures.
