Genentech Expansion Project

This project had a very large concrete pour and various projects at three buildings. Building 9, a manufacturing building, is 86,000 SF, three-story plus a roof, supported by base isolators, and located on a 2.5-acre site. Overaa did two continuous concrete pours two weeks apart, with 6,500 CY of concrete, 90 cement trucks and five concrete pumps. There were scheduling and coordinating issues, plus 86 concrete piers (eight-feet square) and 2.5M pounds of rebar for a three-foot-thick piece of concrete, in the middle of winter. The project included foundations for Buildings 6 and 8, and used grade beams.
