Project Details

The development comprised the folllowing:

• Construction of a new 9 storey apartment and services apartment building including 5 storey carparking and ground floor commercial premises
• Retention of existing heritage facade

Challenge Faced / Engineering Problem Solved:

• Variable founding depths required detailed foundation and pile assessment
• Boundary wall excavations under adjacent buildings required cantilever secant pile walls due to inability to provide temporary ground anchors under neighbouring properties
• Design of heritage facade temporary support systems to allow for demolition of the existing structure

Safe Strong Stable Solution

Construction systems used included:

• Heritage façade retention using vertical and diagonal structural steel bracing systems
• Building supported on a combination of reinforced concrete and steel screw piles
• Cantilever boundary secant pile wall used to excavation below adjacent property foundations and to control groundwater seepage
• Reinforced concrete pile caps, ground slabs, footings and tie beams
• Conventionally reinforced concrete columns, shear walls, cores and stairs
• Post-tension suspended concrete systems
• Structural steel awnings and plant framing
