Garden Island – Wharf Repairs

Description: 

Garden Island Defence Precinct (GIDP) is a key operational and support base for the Royal Australian Navy. It is the major fleet base on the east coast of Australia and its primary role is to support home-ported and visiting Navy ships, as well as those ships belonging to foreign naval partners.

The main purposes of the works being carry out by Freyssinet are to:

  1. Reinstate   the   condition   of   the   wharves   and   infrastructure, accounting   for   deterioration   and dilapidation, and in turn providing fit-for-purpose compliant facilities, wharves and infrastructure, at the lowest possible whole-of-life cost to the Commonwealth;
  2. Increase the efficiency of operation of the service’s infrastructure, and identify and implement synergies;
  3. Account for the future utilisation of wharves and base infrastructure, clearly incorporating provision for future adaptability and flexibility.
