Waikawa Marina - Port Marlborough

Overview

The extension works at Waikawa Marina involved reclaiming 460m of land along ‘The Snout’ in the Marlborough Sounds.

This project won the 2021 Environmental Award at the Nelson/Marlborough CCNZ Awards.

Key project stats:

• This reclaimed land is roughly 15m wide (on average) to accommodate two traffic lanes, car parking, three amenities’ buildings, kerbing, footpath, and in some places, timber boardwalks and timber jetty abutments.
• There has been over 33,000m3 of fill material, and over 4,000T of armour rock (including geogrid and geofabric layers) placed by a GPS enabled 34T digger and a GPS 26T long reach digger for the deeper sections.
• More than 3,000 truck and trailer loads of rock was carted through the heart of Picton township and Waikawa.

Works completed

Some of the challenges we overcame included working in and around water and placing rock underwater and building up rock in compacted layers for future building foundations. We also had to manage the supply of rock from 3 different quarries ensuring they all met the required quality standards.

This project also included site clearance, earthworks, services install, structural piling, metal course carriageway construction, half of all quarry material supply, project management, traffic management and surveying.

The team has made a great effort to complete this work to a very high standard, on time and with positive feedback from the community and our client Port Marlborough.
