San Joaquin Delta College Cunningham Math and Science Center
Thornton Tomasetti is providing structural design services for a 138,000-square-foot, three-story, braced steel-frame building. The central laboratory wing houses dry labs on the first floor, wet biology on the second floor, and chemistry laboratories on the third floor. Featuring a modern, functional design, the labs wrap around a central service core consisting of technical offices, laboratory preparation rooms, and laboratory storage rooms. The laboratory wing is flanked by structurally separated classroom and office wings, which are interconnected with the lab wing via open-air, canopy-covered bridges.
The Center expresses an open design, and includes features such as exterior corridors/balconies with exposed steel braced frames, open cantilevered stair/elevator towers at each corner, and landscaped courtyards separating the building wings.
The structural design includes stringent vibration criteria for the laboratory floors, and expansion joints at bridge-to-building connections to facilitate differential movement between wings during an earthquake.
