The South Perth Esplanade project is an 8 storey high-end mixed-use development. It is the successful manifestation of great design combined with functionality, grace and utility.
The main challenge from a development viewpoint was to maximise the number of floors without exceeding 25m in overall building height. Remaining below this threshold was crucial to avoid more onerous fire engineering requirements and associated additional costs. To remain below this height, the maximum available slab thickness was a mere 200mm, with no additional thickness allowances for transfer elements.
The presence of a restaurant and various commercial units necessitated large open areas (free of columns) on the ground floor, which provided further complexity.
The Hera Engineering team worked very closely with award-winning architects JCY to align the structural columns and shear walls resulting in very few transfer elements and kept the total height of the structure to remain below 25m.
The structural system consists of precast concrete cores and shear walls. The floor system is a post tensioned flat slab with large spans up to 10m.
