Stephenson Engineering is in the process of providing building envelope consulting services related to the removal of the existing 120,000 square foot limestone façade and the design of a new cladding system that is to be incorporated along the lower five storeys of a new 58-storey mixed use high-rise building at 88 Scott Street. The work included the design of the structural support system, wall assembly, specifications, and construction methodologies. The building is currently designated a heritage site by the City of Toronto.
Stephenson Engineering executed the removal and replacement of joint sealant at precast-to-precast concrete panels, perimeter-of-window frames, and metal-to-metal window frame joints, as well as the interfacing of glazing to metal window frames. To meet budget restraints the work was phased over two years, with Phase 1 completed in the summer of 2013 and Phase 2 scheduled to be completed in the spring of 2014.
