The Alaska State Capitol Seismic Retrofit and Exterior Renovation Project is a multi-year Legislative Council Project to provide much needed upgrades to Alaska’s 85 year old Capitol building. The effects of 80 years of weather on the building’s exterior displayed signs of leakage, degradation and stress such as broken bricks and cracked sandstone along the lower wall and portico roof structure. PDC (previously R&M) performed IBC special inspections on the structural work related to reinforcing the portico, column stone repair, repair of concrete interior and exterior structural members, window replacement frames and crawl space improvements. Concrete special inspection work included reinforcing steel inspection, cast in place anchor bolt inspection, and field sampling concrete for slump, air entrainment and compressive strength. Epoxy grouted anchors were inspected throughout the project. Shotcrete special inspection included continuous inspection during placement, observing test panel core samples, and laboratory compressive breaks of the shotcrete core samples. Daily inspection reports were prepared or each inspection visit.
