Evergreen State College Residence Hall A Seismic Retrofit

Durable dorm. The Evergreen State College (TESC) needed to improve the seismic performance for the building that houses first-year students and administrative staff in Residence Hall A. Reid Middleton designed seismic upgrades to mitigate the seismic deficiencies of the 10-story facility used as a dormitory. The reinforced concrete shear walls of the 57,000 SF residence hall built in 1971 needed to be upgraded for additional shear and bending capacity. Three-dimensional renderings of the proposed upgrades were developed by Reid Middleton in Building Information Model (BIM) software, Revit®. The models were then used by the architect and other team members for design as well as for construction documents. The cost-efficient seismic upgrades of $21.05 per SF consist of carbon-fiber reinforced polymer wrapping (CFRP) of the shear walls and external tension reinforcing along the full height of several of the walls.
