Enhancing sustainability through creative construction

Our team on the Eastland Port in Gisborne, New Zealand worked collaboratively with our customer to redesign this new marine berth and deliver outstanding sustainability benefits.

During the six-month value engineering process, McConnell Dowell’s in-house engineering team worked with Eastland Port and, using digital engineering and animation capabilities, redesigned the structure from a retaining wall design to a piled solution.

This removed the need for 49,500 tonnes of hardfill, meaning 3,300 fewer truck movements through the city, saving 220,000 litres of diesel and reducing carbon emissions by 593 tonnes. The solution also reduces steel use by 70% and minimises disruption to port activities.

Further, a drill and drive method will be used in place of driven piles, thereby mitigating noise and vibration on local sealife. Project staging has also been optimised to reduce the overall programme.

Our contract is part of stage one of the project which will enable two handymax (180-200m long) ships to safely load and unload at the port simultaneously.
