Abstract

Owned and developed by Precinct Properties, Commercial Bay will reshape the waterfront area bounded by Britomart, the Viaduct and the CBD, and resurrects the location’s original name. The project integrates the new components with the existing office buildings (Zurich House and HSBC House) to create a working population of 10,000 people. The project includes a new 39 level commercial office tower and 18,000m2 of retail space, which will make Commercial Bay the largest mixed use development in the Auckland CBD.

One of the main complexities for the Commercial Bay project is the integration with the separate, isolated CRL rail tunnels which run through the site and beneath the tower. This has required large trusses beneath the tower to transfer load out to the surrounding walls and columns on either side of the tunnels. Another project complexity is the three levels of basement across the majority of the site.

The structural system of the tower is an elastically braced steel frame. The retail component consists of a range of structurally separate but architecturally linked buildings. The main retail structure consists of a concrete moment frame building with three levels of basement and three suspended levels. Two other retail buildings are steel moment frames, and a fourth is a smaller concrete moment frame building.

The Commercial Bay site is currently in construction with the tower structural steel presently over half way, the concrete moment frame retail building on the corner of Queen and Customs street complete, and the rest of the retail buildings moving forward quickly behind them.

Chris Mackenzie and Annie Scott from Holmes Consulting will give an overview of the project and the structural challenges.
