The Queens Wharf Skydeck, Brisbane
The Skydeck is constructed from steel and is comprised of three spans of 25 m, 30 m and 35 m, bridging between the towers of the development (IT1, IT2, IT3 and IT4). Two spans (IT1-IT2 and IT3-IT4) are designed with permanent movement joints to allow the independent movement of the connected towers. The IT1-2 span presents a unique challenge. It bridges from the side of Tower IT1 from a fixed deck projecting up to 12 m from the tower’s façade line, requiring a sophisticated articulation joint. The spans of the Skydeck are assembled and clad at the podium level, then slid horizontally into position via a rail system, before being vertically strand jacked.
