Our engineering and design services range from planning and regulatory approvals, geotechnical investigations, preliminary and detailed design through to start-up and commissioning for all types of projects. Using proven methods of coordination and effective collaboration tools, we partner with clients, accessing our highly experienced team of approximately 7,000 professionals operating on six continents and 35 countries, and local New Zealand expertise to deliver projects with strict management of quality, value, schedule and cost.
Success from Innovation
Our innovative design techniques won two awards in the 2014 Institute of Public Works Engineering Australasia, New Zealand Awards including an award for the design, delivery and development of the Eastern Selwyn Sewerage Scheme at Rolleston near Christchurch. New Zealand’s first solar air drying hall for biosolids provided a cost saving of about $3 million to $4 million NZD by reducing the sludge needed to be carted off site for disposal.

Our New Zealand transportation team has also completed innovative design work on the SH1 Waikato Expressway (Rangiriri Section). The design included an innovative interchange design to overcome the complex integration of a long single-lane bridge on one of the approaches, effectively creating a 400 m long signalised intersection.
Dynamic microwave sensors were used that detect late arrivals on the bridge and extend the signal phase times to allow them to safely cross the bridge and clear the intersection. MWH designers also incorporated extensive use of stone columns in the design to combat the complex localised problem of liquefaction.
