1 The Commercial Bay Development is the largest mixed use development ever undertaken in the Auckland CBD. The project combines two existing office towers with a new three level high-end retail complex and a new 39 level commercial tower—all above three levels of basement car parking and two train tunnels, with associated major complexities and structural transfers.
2 The architecture of the flagship 39 level Commercial Bay Tower in downtown Auckland celebrates and showcases the structural form of the building. Working closely with the architect and the wider project team, Holmes designed visually striking columns and diagonal braces, which are clad to express and accentuate the structure.
3 In a large complex project with many stakeholders and challenges, the Commercial Bay Tower is an example of a well coordinated structure, underpinned by great BIM execution and a willingness for project partners to work through challenges collaboratively. This result was achieved through excellent continuous ongoing collaboration and communication between project stakeholders—particularly the architect and the structural engineers. Weekly exchanges of Revit files via a shared FTP site ensured well-coordinated Revit models, and delivered a clear accurate picture of progress.
4 With a premier site overlooking the Waitematā Harbour, the Commercial Bay Tower (opened in mid-2020) is now considered an iconic landmark on Auckland’s foreshore and city skyline.
