Seismic retrofit of a 10,500 sf unreinforced brick and wood roof and floor structure built in 1910 within the Western University Campus.
The work included the addition of new reinforced concrete shear walls and foundation. The project included construction of new office space and tenant improvements and seismic bracing of existing mechanical ducts and fire sprinkler systems.
Upon completion of the retrofit measures, the estimated damage levels, anticipated during strong ground shaking at the site, will be reduced considerably from those prior to retrofit. Probable maximum loss estimates (PMLs) produced for this structure, after retrofit, will reflect a significant reduction in potential financial loses.
TES provided assistance during construction with the bidding process and performed structural observation in accordance with the requirements of the CBC.
