The InQuik Bridge System is an Australian innovation that was first conceptualized in 2015. Since its introduction into the market in 2017, it has been rapidly adopted in the Australian bridge market, with more than 160+ bridges in service or under…

Visualisation tools are often used during concept development to assist in developing feasible options and also for further consultation with stakeholders and other interested parties to gain approval for further progression of the project.…

Transport for NSW (TfNSW) utilises various electrochemical protection systems such as cathodic protection, chloride extraction and re-alkalisation. Whilst the technical merits for re-alkalisation and chloride extraction are proven, there have been…

The innovative Viaduct over Muscle Creek and Hunter River with an overall length of 178.4m comprises four spans of 45.7m by 50m by 50m by 29.7m and 1.5m length beyond the bearings at each abutment, to suit a challenging and restrictive site. The…
