Singapore - Arcadis has been announced as a finalist in the Bentley ‘Be Inspired’ Awards for the CityLink Tulla Widening project in Melbourne, Australia
To be presented during the Year in Infrastructure Conference in Singapore, October 10-12, the Bentley ‘Be Inspired’ Awards celebrate the outstanding use of BIM (Building Information Modelling) in infrastructure projects across the world. Arcadis is a finalist in the BIM Advancements in Bridges category, for the CityLink Tulla Widening Aracdis – WSP/PB Joint Venture.
The CityLink Tullamarine corridor is one of Melbourne’s most heavily used freeways, with traffic forecast to increase to approximately 235,000 vehicles per day by 2031. The CityLink Tulla Widening project will increase capacity, reduce travel times and improve safety on CityLink and the Tullamarine Freeway.
LendLease Engineering is constructing the section of the highway from Melbourne Airport to Bulla Road, with Arcadis-WSP/PB Joint Venture undertaking the design of freeway widening, drainage, ITS (Intelligent Transport Systems), and structures, including the English Street Bridge Replacement. A two-span, cast in-situ portal frame structure from the 1960’s, the bridge needed to be demolished and rebuilt utilising a slender superstructure and designed as a single-span integral steel trough bridge.
Constrained by a short construction time, limited hours of night work, a nearby tramline, and the reinforcement complexity of integral structure type, the design of English Street Bridge was completely modelled in 3D where detailed reinforcements at critical interfaces are developed. This detailed 3D modelling allowed for the investigation of constructability in staging, clash detection, and provided a precision level of accuracy.
The digital build of the project allowed for the successful completion of the English Street Bridge in three weeks, from demolition through to re-opening, minimising the impact of the rebuild on traffic and the local area.
