A glazed curtain wall system was cold-warped on site to achieve the twisted building geometry. Other features include stainless steel and glass balustrades, flush-glazed window walls, ‘lift-and-slide’ balcony door systems, and motorised windows controlled by the Building Management Systems (BMS).
Glass options were sourced globally by the client, and a prototype was crane-lifted on site to ensure the desired appearance and reflectivity when viewed from all angles. Extensive durability testing was then carried out to determine the long-term performance of the glazing and structural silicone when the facade panels were cold warped.
The building’s organic form translated into many unique panels that each required unique glass, steel backpans and framing members. We used our in-house RFID tracking system to monitor all stages of delivery and components.
The facade panel shapes were derived using parametric 3D modelling—each modelled in its curved form, then flattened for manufacture and assembly. A 60-degree twist in the external surface was accommodated for, so panels could be cold warped on site, during installation, into their final form.
“Working on complicated facade geometries with challenging installations and construction programs, their cross discipline expertise, through design, offshore logistics and installation management, provides our projects a high degree of comfort and certainty on a critical work element key to project success.”Tim Whelan Senior Construction Manager - Lendlease Construction
