GHD provided Independent Verification, Testing and Audit (IVTA) durability assurance for concrete and structural steel for construction of a spectacular skyscraper in Dubai.

GHD was initially appointed in 2004 to design and review the installation of a cathodic protection system to protect the reinforced concrete piles and raft foundation, as well as to provide advice on securing the long-term durability of the foundations for Burj Dubai.

Calliope South Wharf access jetty

image

GHD has delivered Cathodic Protection (CP) repair services to the Calliope South Wharf Access Jetty in Devonport New Zealand. Owned by the Royal New Zealand Navy (RNZN), the Jetty is a pre-cast pre-stressed reinforced concrete structure built in 1982 that connects the outer wharf to the landside base..

The pre-stressing tendons of the main beams of the jetty structure were found to be suffering from corrosion, due to high concentration of chloride ions from the surrounding environment and low concrete covers. The RNZN sought a long-term solution to the deteriorating concrete elements to avoid repetitive repairs.

Eleanor Schonell - bridge durability

image

GHD provided durability assurance as part of design and construction support for the 100 year design life, with review to extend to 150 years. Opened on 17 December 2006, the Eleanor Schonell Bridge is Australia’s first bus, cycle and pedestrian-only bridge. It links Brisbane’s Southern suburbs and the St Lucia campus of the University of Queensland. GHD provided structural and civil design for the AUD55M project for Brisbane City Council.

The cable-stayed steel composite structure is only the third of its kind to be built in Australia and is an impressive 520 metres long, with a 185-metre main span. The harp configured support cables are suspended from two reinforced concrete towers rising 70 metres above the river. This landmark infrastructure project features a number of environmentally sustainable design elements, including bio-retention ponds to control the quality of water run-off, minimal use of refill from off-site sources and a bridge alignment that has saved a number of native trees.

Glenelg Gates condition assessment

image

The Department for Water (previously the Department of Water, Land and Biodiversity Conservation) commissioned GHD to undertake a condition assessment of the Glenelg Gates structure. It is situated between Holdfast Shore Marina and the Patawalonga Basin at Glenelg, Adelaide, South Australia.

The purpose of the project was to provide a detailed condition assessment of the existing sub-structure and super-structure to allow consideration of refurbishment options for a minimum remaining service life of 40 years.

Lake Manchester Dam concrete crack and durabaility assessment

image

Dam upgrade works were required for a dam with a high hazard rating in accordance with Australian National Committee on Large Dams (ANCOLD) Guidelines on the Consequences of Dam Failure. The concrete gravity dam was strengthened with post tensioned anchors, requiring an increased crest height and new spillway floor and walls.  The dam raise used precast concrete boxes for permanent formwork that were then filled with concrete and post tensioned to the dam body and foundations.  

The design was to be in accordance with current accepted national practice for dam engineering so that the dam was of a standard of safety that satisfied the requirements of the owner, the relevant statutory authorities and the community.  Durability assessment by a specialist consultant was recognised as important and formally required for the project.
