Structural design services were provided by MPC for this $20million development comprising a multi-level office complex with basement carparking. Structural design of the development addressed issues such as hydrostatic pressure acting on the basement carpark, and piled raft design due to deep underlying soft soils. Earthquake assessment of the structure accounted for the significant building eccentricities and soft soils. A rail impact assessment and risk analysis for an adjacent railway was incorporated into the project and reviewed by MPC to satisfy the Rail Corridor Infrastructure Corporation. The chosen structural solution included continuously reinforced tanked basement slabs, precast articulated basement walls and a concrete framing system providing a ductile structure for earthquake design and rail impact. Post tensioned concrete floor slabs for the upper levels were chosen to achieve the required large spans of 12m. This arrangement assisted in minimising foundation loads, proving beneficial in the piled raft assessment.
