The proposed Auckland City Rail Link (CRL) is considered to be the most significant improvement to Auckland’s transport network since the opening of the Auckland Harbour Bridge. We are providing station design, fire and life safety, operations, rail systems and pedestrian modelling to this public transport system supporting Auckland’s population and economic growth.

Also in Auckland we were technical advisor for the $4-5 billion Additional Waitemata Harbour Crossing. Mott MacDonald undertook a feasibility study and option assessment for a combined road and rail tunnel crossing the harbour.

Mott MacDonald is providing structural and façade design and buildings services technical advice for the $35 million Carlaw Park postgraduate student accommodation. After developing a number of options we selected a cost-effective hybrid structural steel and pre-cast concrete floor solution that provided both structural savings and savings through improved space planning for the apartment and car park layouts. 

We're also working on a number of projects at the University of Auckland, including the new Science Centre 302 building. We are providing building envelope performance modelling and façade design. Our analysis has assisted with savings of NZ$2 million on the façade as well as enhancing energy efficiency by reducing the required cooling and heating capacity.  

We are also providing façade engineering for 45 Queen Street office tower, and New Lynn Merchant Quarter, Auckland as well as Burwood Hospital in Christchurch.

Mott MacDonald is providing specialist maritime advice to Auckland Transport on the new ferry terminal at Quay Street, and provision of operational and patronage input into the masterplan.

This commission is currently developing and our global expertise will be used to provide best practice techniques to the future terminal, ensuring that it links successfully to the city as well as other proposed developments in the area.

We will also test operator requirements for the terminal which will assist in determining the required alignment of the new quay wall. The successful completion of this project involves an intimate understanding of the wider context including existing and future adjacent spaces and activities.

With the addition of specialist water technology and consulting company AWT, headquartered in Auckland, we offer leading-edge technical solutions across the project cycle and covering all aspects of collection, conveyance, treatment, reuse and residuals incorporating water, wastewater and storm water. Core services include network monitoring, project planning and management, modelling, design, commissioning and optimisation.

AWT recently supported the expansion of the Rotorua treatment plant and applied membrane bioreactor technology to meet New Zealand’s tightest nutrient limits from a wastewater discharge. AWT has also implemented a new NZ$20 million membrane water treatment plant for Taupo to remove arsenic from the source water. And, AWT has developed the H2knOw-how middleware data management platform which is being used by water utilities across the region. In Christchurch City it has been adopted to provide network monitoring data and analysis to assist with rebuilding underground water assets.
