Project Details

The development comprised:

• Refurbishment of existing two storey steel framed building
• Retention of heritage façade and creation of new auditorium foyer and amenities
• New performance facility including stage with subfloor, and tiered seating

Challenge Faced / Engineering Problem Solved:

• Mine Subsidence Design Reviews
• Increased Earthquake Design requirements due to deep soft soils
• High water table causing hydrostatic uplift pressures on the building
• Construction over a main stormwater drainage channel whilst maintaining the heritage façade
• Strengthening modifications of existing 2 storey building to account for new loadings and lift structure

Safe Strong Stable Solution

Construction systems used included:

• Building supported on steel screw piles
• Continuously reinforced basement and ground floor slabs
• Watertight basement perimeter walls
• Structural steel and timber framed stage
• Structural steel framed tiered seating with precast planks
• Structural steel framed roof and awnings
