Innovative Steel Structures at Auckland Zoo: The Southeast Asian Precinct Project

The Southeast Asian Precinct, a new highlight at Auckland Zoo, features a unique high canopy primate habitat designed for orangutans and siamangs. Known for their life high in the trees, these primates now enjoy an expansive network of aerial pathways that enhance their climbing range. This standout project was a finalist in the $1.5m - $3m category at the 2020 SCNZ Excellence in Steel Awards.

Project Overview:

Structure Type: Steel structures, including nine towering 20-25m-high poles with intricate linking ropes, stretch across the zoo’s landscape, including an ambitious extension over the lake.

Innovative Construction Approach: Originally designed with complex welded rings at significant heights, George Grant Engineering (GGE) proposed a crucial modification to enhance safety and efficiency. By lowering the splice in the pole, the climb stopper was integrated into the top section during ground-level assembly. This adjustment significantly reduced the risks associated with high-altitude work.

Assembly and Installation: The re-engineered poles, complete with climb stoppers and safety mesh, were pre-assembled safely on the ground. Cranes were then employed to elevate the fully prepared sections into place, showcasing an exceptional example of innovative construction techniques.

Project Team:

  • Structural Steel Contractor: George Grant Engineering (GGE)

  • Steel Modeller: 3D Steel
