HOLCIM - EXCELLENCE FOR ARCHITECTURAL CONCRETE (MONTE CRAVEN AWARD)

Hynds Pipe Systems for Te Pae North Piha Surf Life-Saving Tower, Auckland

The brief was for the lifeguard tower at North Piha - one of the most beautiful but dangerous surf beaches in New Zealand – to be a robust, low-maintenance building that would withstand the severe coastal environment. As the site is remote, precast concrete was chosen for factory manufacture and assembly on-site. The tower is made up of 10 bespoke elements, with the shaft sitting on an in-situ concrete foundation to support the podium elements that cantilever towards the sea. The result is a facility that meets community needs now and into the future.

GOLDEN BAY - EXCELLENCE IN CONCRETE INFRASTRUCTURE

Fulton Hogan Taylors Joint Venture for the Waimea Community Dam, Tasman District

Waimea Community Dam, Tasman District.

The dam is one of the region’s most important infrastructure projects and the largest dam built in New Zealand for over 20 years. The project team developed new approaches to achieve a high-quality concrete outcome. Key to success was placing over 30 thousand cubic metres of concrete in a remote location for a range of structures, that included a diversion outlet, starter dam, plinth, spillway, and the embankment’s concrete face.

GOLDEN BAY - EXCELLENCE IN CONCRETE INFRASTRUCTURE (HIGHLY COMMENDED)

Downer New Zealand for the Tekapo A, Intake and Shaft, Canterbury

Tekapo A, Intake and Shaft, Canterbury.

This unique engineering project protects one of the South Island’s key hydro-power schemes by allowing the flow of water to Tekapo A, Power Station to be stopped in an emergency shutdown. Engineering smarts were developed that maintained live operations throughout construction. These included using shotcrete to build the shaft in layers, expediting the construction programme and building a permanent stent to sustain power generation.

Genesis Energy, AECOM, Parfitt Construction, Kiwi Concrete, Complete Reinforcing and Downer New Zealand.

GPIL - MATEENBAR - EXCELLENCE IN CONCRETE LANDSCAPING

Allied Concrete for the Ōpuke Thermal Pools & Spa, Methven

The entire complex was conceived as a journey through nature, emulating the context of the Canterbury Plains as they meet the majestic alps. The main feature is the hard landscaping, which uses shotcrete and decorative concretes. A striking element of the facility is the cave system, with complex shapes formed using large bags of sawdust as the backform.

BCITO TE PUKENGA - EXCELLENCE IN RESIDENTIAL CONCRETE

Young Architects for Scarborough Béton Brut, Christchurch

Strong and efficient, concrete was used to retain the hillside, and for the finished internal walls. The structure itself was insulated and left exposed, allowing concrete's thermal mass to optimise a passive solar design that allows for comfort all year round. Resilient in the face of strong winds and seismic threats, the concrete also offers honest beauty, with the strong timber grain shuttering giving an aesthetic that is raw like the environment. In short, the home is efficient, permanent, and stylish.

Young Architects, Hoogervorst Builders and ENGCO.

FORMSHORE - EXCELLENCE IN CONCRETE REMEDIATION AND REUSE

Downer New Zealand for City Rail Link C1, Auckland

City Rail Link C1, Auckland.

The CRL Contract 1 and enabling works at Britomart involved extending the rail network from Britomart Station, underneath the historic Chief Post Office and Lower Queen Street, one of the busiest areas of the Auckland CBD. The construction of twin rail tunnels beneath the historic Chief Post Office presented significant challenges for the project team, which led to innovations such as post-tensioning and cement jet grouting as part of the underpinning works, and the construction of concrete diaphragm walls beneath the building.

Project Team.
Auckland Transport, Soletanche Bachy, Aurecon, Freyssinet, Allied Concrete, Acrow and Downer NZ.

POWERPAC GROUP - EXCELLENCE IN CONCRETE FOR THE COMMUNITY

Downer New Zealand for the Downtown Infrastructure Development Programme

Downtown Infrastructure Development Programme, Auckland.

This 350-million-dollar redevelopment of the downtown area had an ambitious timeline, with the America's Cup and other international events on the horizon. There were numerous large concrete-based components erected and cast over the water, and significant architectural concrete finishes that enhance the streetscapes. Notable amongst these were the seismic strengthening of the 100-year-old seawall on Quay Street and the Te Wānanga Downtown Public Space - the project's centrepiece.

POWERPAC GROUP - EXCELLENCE IN CONCRETE FOR THE COMMUNITY (HIGHLY COMMENDED)

Aurecon for Nga Hau Māngere, Auckland

In partnership with mana whenua, the project team replaced the 105-year-old Old Māngere Bridge with a new, stunning piece of structural engineering which, at 260-metre-long, has an elegant, curved design with a wide deck allowing pedestrians and cyclists to travel safely. The cornerstone of the bridge is a dramatic 60-metre central arch, supported by a concrete superstructure, which provides a fitting sense of scale to the neighbouring motorway bridges. Challenges during construction included the tidal environment and the complex structure.

EXCELLENCE IN EXCELLENCE IN CONCRETE INNOVATION

Allied Concrete for e-crete^TM

Allied Concrete for ecreteTM.

With a reliable supply of ground granulated blast furnace slag now available in New Zealand, Allied Concrete undertook an R&D programme to develop a range of lower embodied carbon concretes known as ecrete^TM. These are being used on a limited scale in Auckland with wider release planned for later in the year. These concretes are designed to utilise SCMs and other concrete mix technology to achieve lower carbon outcomes through cement substitution of up to 60 percent.
