Since 1971, Warren Hall stood as the highest building in Hayward at California State University East Bay's campus. The 13-story, 530-foot building did meet the code requirements and was considered siesmically unsound.
FBA Inc. prepared engineering demolition plans. Taking down the building posed an engineering challenge because of the tower's proximity to the library and several other campus structures. Special timed charges were stratigically placed so the building would lean and keep the 12,500 tons of concrete rubble and steel away from the other buildings.
