Waikawa Marina Extension Reclamation Works

The Waikawa Marina Extension Contract involved reclaiming 460m of land along ‘The Snout’ in the Marlborough Sounds. 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 had to be carted through the heart of Picton town and Waikawa, passing by three schools and the main Picton town centre. 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.

This project included site clearance, earthworks, services install, structures piling, metal course carriageway construction, half of all quarry material supply, project management, traffic management and survey. It involved working in and around water, 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.
