The Concrete NZ Learned Society’s prestigious 2019 Concrete Award has been won by Beca’s Waterview Connection entry, a $1.4 billion project that was the largest road project ever undertaken in New Zealand.

The Concrete NZ Learned Society’s prestigious 2019 Concrete Award has been won by Beca’s Waterview Connection entry.

The $1.4 billion project was the largest road project ever undertaken in New Zealand.

It involved the construction of 4.8km of new motorway which links SH16 and SH20 together to complete the Auckland Western Ring Route.

It has relieved regional congestion and provided a direct link between the Auckland CBD and Auckland International Airport.

The project work includes two parallel 13.1m diameter tunnels 2.4km long, two cut-and-cover tunnel approach trenches, and four interchange ramp bridges where the motorway emerges at Great North Road.

The project was delivered by the Well-Connected Alliance (WCA) which comprised the New Zealand Transport Agency, Fletcher Construction, McConnell Dowell Constructors, Beca, Parsons Brinckerhoff, Tonkin and Taylor, and Japanese construction company Obayashi Corporation.

The Great North Road Interchange ramps comprise four separate viaducts connecting the SH20 tunnels with SH16.

The lengths of the bridges range from 225m to 500m, with horizontal radii as tight as 240m.

The Learned Society panel commended the WCA and all the teams involved with this large-scale, ambitious transportation project.

“Incorporating many elegant components and complex scale features, and addressing a multitude of technical and logistical challenges, The Waterview Connection is an outstanding achievement with immense benefits to the region,” the panel said.

“The WCA is a worthy winner of the 2019 Concrete Award.”
