The Tranche 1 projects are the first Stage in many proposed stages on the Unitec campus redevelopment as part of the pedagogical transformation. The $23m CET building is a large format single storey long span structure to house Trades education spaces, and includes large mezzanine structures and part basement. The CET building is futureproofed for a 4 storey Performing and Screen Arts (PaSA) building oversailing the Trades structure. The $19m Hub project is a highly complex structural engineering and architectural challenge, incorporating a steel collar jointed 2 storey sway frame structure with tree columns supporting a glulaminated diagrid roof. The structure also incorporates intricate 4 storey high, 2m thick wing walls. The entire structure oversails, and is seismically isolated from, the surrounding existing buildings.
