The $16.8 billion WestConnex project will provide 33 kilometres of motorway connections from western Sydney to Sydney Airport and Port Botany, transforming urban travel and providing better connectivity between key employment hubs and local communities.
In this presentation from Road and Rail 2016, Adrian Bull, Director Technical Services, Sydney Motorway Corporation, explores:
- The challenges of constructing the new twin tunnels which are higher and wider than most current Sydney road tunnels
- Types of geotechnical investigations utilised to understand ground conditions for tunnelling option studies
- New precast bridge design and options considered
- Asset management and maintenance considerations
In creating a framework to communicate professional opinion to decision makers, asset managers are faced with managing and analysing vast amounts of technical data, and consequently the challenge of communicating the analysis. In this presentation from Road and Rail 2017, Angela Hili, Project Manager, Transurban, explores:
- The effectiveness of a model framework to process and refine large amounts of data into manageable, communicable information in order to make sustainable business decisions
- Identification of optimal existing capacity through study of functional and structural elements of the Motorway, within a networking setting
- The process adopted in streamlining initiatives and the multi-criteria analysis involved to develop a programme of works
In this presentation from Road and Rail 2016, John Hilton, Technical Director, Expertise Leader Bridges, Aurecon Group, explores the design of tall piers with reference to recent international bridge projects and current codes and specifications. Projects discussed include pier heights of up to 86m.
The 2011 West Gate Bridge Strengthening Project warranted preparations of a complete overhaul of the operation and maintenance manual that incorporated new structural elements that were added as a result of the strengthening project, and allowed the manual to be updated for actions observed from the operation of the bridge over the past 35 years. Now the bridge has been operating for some 5 years since the strengthening works.
In this session from Road and Rail 2016, Scott Taylor, Team Leader – Structures, SMEC, explores:
- The composition of the manual, and categorisation the structure into its basic structural components
- Summary of the strengthening works and current works being undertaken on the bridge
- Revisiting assumptions made to determine critical elements, frequency of inspections and maintenance activities
- Review of the use of the manual by the maintenance team
