Wynyard Place will transform Wynyard into a world-class urban precinct in the heart of Sydney’s CBD. The centerpiece of the development is a new 27-story commercial tower. The project also includes the restoration of heritage buildings Shell House and 285 George Street, returning them to their original use. Wynyard Station’s George Street entrance will undergo a major upgrade with the installation of a grand transit hall and public concourse, along with improved pedestrian links and facilities.
This presentation provided an overview of the development and the associated structural design challenges overcome by the team, such as the following: (1) maintaining public access through the site during demolition and construction, (2) overcoming restricted site constraints and access, (3) restoring heritage structures, (4) transferring the tower lateral stability system to suit the building’s mixed uses, and (5) maximizing the number of floors within the building planning height limits. Some solutions to these challenges included integrating temporary and permanent works to achieve the desired outcome whilst minimizing construction program and cost. Temporary works are interspersed into existing structures to facilitate safe public egress during staged demolition. Similarly, new works are tailored to allow for construction staging, elimination of back-propping, and the provision of overhead protection for safe public egress.
