Cable Tunnel Litigation


GHD provided Expert Witness Services over a period of three years, in response to a summons filed in the Supreme Court of NSW. GHD received instructions from lawyers acting on behalf of one of the co-defendants and their insurers.

The matters involved alleged defects in the design of a partly unlined tunnel in the Hawkesbury Sandstone, with regards to permissible water inflows, drainage, rock support and the accumulation of iron “sludge” (ferric oxy-hydroxide precipitate) deposits in the tunnel over time. The case was concluded successfully by a negotiated settlement at mediation and Notices of Discontinuance were filed in the Supreme Court of New South Wales in May 2014.

Sydney Primary Loop


Jemena’s Sydney Primary Loop (SPL) is a 29km DN500 pipeline which runs through south western suburbs of Sydney from a connection to an existing section of the DN550 primary loop pipeline at Casula and ties in into the existing DN550 primary main pipeline at Marrickville.  The SPL pipeline connects two major Jemena Gas Networks primary mains, thus enabling continuity and reliability of gas supply if the supply on either is interrupted.  The SPL pipeline also provides further opportunity for development of the gas distribution network in Sydney area.

The facilities and stations on the SPL pipeline include Automatic Line Break (ALB) main line valve stations, a Primary Regulator Station (PRS) at Moorebank and a Trunk Receiving Station (TRS) at West Hoxton.  GHD was selected by Jemena to undertake engineering design and construction support for the pipeline and associated stations.

Australia is at the forefront of solar research and development and the Australian Solar Institute's role was to keep it there.

GHD provided the Australian Solar Institute (ASI) with communications support, providing a variety of communication materials and a long-term communications plan which GHD assisted ASI to initiate but which ASI could deliver into the future.

Swansea Bridge Cathodic Protection Work


Swansea Bridge at Lake Macquarie in New South Wales is an opening bridge to allow vessels to pass underneath and was constructed in the mid 1980’s. Since then, harsh marine exposure conditions had resulted in corrosion and bridge deterioration. A solution was needed to increase the longevity of the bridge.

Working with the Roads and Traffic Authority NSW (RTA), GHD helped develop a long-term, environmentally-sustainable durability solution to be adopted  which would increase the bridge’s longevity plus minimise community disturbance and achieve best value for money outcomes.

Rouse Hill Recycled Water Plan


Sydney Water in partnership with Sydney Water Corporation, John Holland, Thompson Controls, and GHD delivered the $60 million Rouse Hill Recycled Water Plant – stage two amplification project. This is the Southern Hemisphere’s largest residential water recycling scheme.

Initiated in September 2006, the project doubled the capacity of the existing waste water treatment plant to 27 million litres a day and increased the recycled water capacity to 4.7 billion litres a year (this will supply 36,000 homes in the local community at project completion).
