UCB Latimer Hall Seismic Retrofit

Project Details

Latimer Hall was orginally built in 1963 and houses the Chemistry Department at UC Berkeley. It was in this building that Dr. Glenn Seaborg and his colleages discovered transuranium elements and identified more than 100 isotopes of elements throughout the Periodic Table. The Latimer Hall Seismic and Safety Project for the UC Berkeley College of Chemistry involved seismically retrofitting an existing 10 level, 195,630 sf cast-in-place structure. The building remained occupied during construction. The retrofit required the strengthening of exterior footings and walls from both the interior and exterior of the building which involved excavations to 34′ below ground level, interior footing tie-downs to minus 45 ft from the lowest point in the building. Overaa installed 1’7″ concrete column cladding to 103′ above the Plaza level and 1’7″ x 5’6″ high spandrel beams the enitre length of the building. Overaa used 6′ wide x 50′ long mast climbers, drill rigs that can fit through 3’x7′ openings, and environmentally friendly equipment such as vacuum attached drills and water blasting versus sand blasting.
