Having been crowned as the category winner in SCNZ Excellence in Steel Construction in 2024, the architecturally stunning 71m-long pedestrian and cycling bridge is a prominent gateway (waharoa) to the new Waikato River crossing.
The Facts
- · 71m-long bridge
- · 200 tonnes of weathering steel
- · 195 tonnes of structural steel
- · 25m-high upright steel masts
- · 100m radius
- · 3-span bridge
- · 5-module construction
A Complex Steel Project
The geometrically complex structure comprises five sections, totalling nearly 200 tonnes of weathering steel along 71 metres. Two 25 metre high taurapa (steel masts) feature twin skins, with the external skin showcasing Māori artwork. The bridge employs a simple box beam structure, supported by stiffeners and diaphragms, which form the outer skin and deck.
Steel shrouds enclose the earthquake bearings and joints, connecting them to the reinforced concrete cantilever beam and pier.
The Engineering Challenge
The complexity of Taurapa Bridge demanded more than a traditional design and build handover. PFS Engineering was brought in early under an early contractor involvement model (ECI), which proved pivotal in ensuring the bridge’s ambitious architectural and structural goals could be realised efficiently and cost-effectively.
Fabrication was driven by a 3D model, which enabled detailed drawings for every component.
A True Partnership
Delivered collaboratively by PFS Engineering, BBO, Edwards White Architects and cultural artist Eugene Kara, Taurapa Bridge enriches infrastructure and honours local narratives.
“PFS has delivered an outstanding piece of steelwork that not only adds to Hamilton’s distinctive river identity, but showcases our local expertise and the benefits of partnerships.”
