Estructure provided structural engineering services for the enclosure of an existing steel frame at Building B77 on the Lawrence Berkeley Lab campus. The existing steel frame structure occupies approximately 2,880 square feet and is an exterior extension of the main building’s structural and crane system. Estructure designed a seismic upgrade to the building, triggered by the increased weight of the cladding and MEP system upgrades. The seismic upgrade included strengthening existing moment frame connections and installing new braces. The MEP upgrades included a new air-handling unit on the roof. The new cladding system was designed to incorporate the existing crane system and to integrate with the existing building cladding. The enclosure houses a 70,000-pound waterjet, for which Estructure designed seismic anchorage. Estructure also designed an interior, standalone staff office with a roof designed for storage loading.
