Document Description
The proposed project consists of a seismic retrofit of the N Building at Patton State Hospital. The N Building is categorized as a Risk Level VI on an I to VII scale, with VII being the highest risk level in the scale. This means that in a maximum credible earthquake, there would be extensive structural and non-structural damage, with collapse of some of the building components likely to occur. The seismic retrofit is necessary for the life and safety and security of the building occupants. The proposed seismic retrofit project would bring this building to Risk Level III. The proposed project includes construction of exterior concrete buttresses, strengthening end walls by eight-inch thick shotcrete at each wing, and installation of carbon fiber reinforced jackets for columns. The buttresses would by 15-inch thick reinforced concrete walls supported by three-foot thick reinforced concrete slab/pile cap with twelve 18-inch diameter drilled and cast-in-place piles. The buttresses would be located on the exterior of both stories in four locations on each of the radiating wings of the N building.
