Spantech worked with Misho + Associates to design and construct the base structure for the Nocturnal Animal Enclosure.
Key to the success of this project was Spantech’s ability to meet the project’s budget while delivering a structure as close as possible to the Architect’s original vision.
The original design incorporated three separate earth-covered structures using a precast concrete arch system. Construction of this approach proved too expensive. It would also require painting of all internal concrete surfaces and future maintenance of the finish.
Spantech’s solution was to construct a single building instead of three structures and cast in a number of small precast concrete tunnels to create emergency exits where required.
The Woomera 300 profile was used as the permanent in situ formwork to a reinforced, shotcrete concrete arch. This method was faster and more cost-effective than the precast option. The Spantech formwork was manufactured from Z-600 coil steel, which Spantech had pre-painted in matte black. The internal finish is now a maintenance-free strung metal lining, impervious to leaks.
