These projects included the seismic anchorage of over 100 mechanical units, testing and manufacturing assemblies and piping and support frames. Raised access floors as high as 36-inches, and equipment as heavy as 12,000 lbs were anchored within a class 10 clean room for MMC Technology. Equipment anchorage was designed and installed for both upper floor and rooftop locations for LSI Logic. For Gemfire, the tenant elected to do a voluntary seismic upgrade to the building, as well as roof & floor mounted equipment anchorages and raised access floor installations.
