NCIS 2 Armament Wharf Extension

Project Overview

Ertech and joint venture partner Duratec was awarded the contract to construct a 107° extension to the Armament Wharf at HMAS Stirling on Garden Island, WA. The wharf will consist of a concrete wharf deck, one berthing dolphin, two mooring dolphins, cathodic protection, construction of wharf services and provision and installation of wharf furniture.

5.4% of total man hours worked on site were by Indigenous Personnel. Ertech also engaged a seventeen-year-old indigenous project administrator trainee who completed a Certificate IV in Business Administration. This trainee’s commitment to quality meant she was nominated for the CCF Aboriginal Trainee of the Year Award.
