Detailed investigation and live-load evaluation was undertaken for several 1930s reinforced concrete bridges followed by strengthening where required.

The role of effective project/contract management in the successful delivery of Impressed Current Cathodic Protection (ICCP) systems has been recognised by RMS specification for ICCP, BS361, which has comprehensive provisions for the supervision of…

As bridges age and standards evolve, it has become increasingly necessary to strengthen existing bridges as a much cheaper option than replacing bridges as a whole.

AS 5100 was originally developed for the design of new bridges. There are however, approximately 20,000 existing bridges in Australia. Although Part 7 of the Standard relates to the strength rating of existing bridges, the existing AS 5100 generally…

The New Zealand Transport Agency (Transport Agency) has recently published ‘Protective Coatings for Steel Bridges: A Guide for Bridge and Maintenance Engineers’. This was prepared by the authors to optimise the long-term capital and maintenance…

Inspection of bridges often requires high-risk operations such as working at heights, in confined spaces, in hazardous environments, or sites inaccessible by humans. There is significant motivation for robotic solutions which can carry out these…

Case studies of bridges located in the Lockyer Valley in Queensland and the Solomon Islands are presented in the paper. Historically these locations have experienced extreme flooding. Flood damage at bridges can isolate communities and result in…

Victoria has experienced a number of large-scale and intense flood events in the last four years. An assessment has been undertaken of the structures impacted by these flood events.The objective was to better understand the impact of the floods on…

A key element of optimised asset management involves determining the type and timing of maintenance and renewals actions to achieve the least whole-of-life cost. This can often be a very complex process in reality because of the many different…

As part of the ongoing upgrade of timber-piled bridges on the North Island Main Trunk, KiwiRail identified three bridges (BR 280, 281, 282) to be replaced in 2012. These bridges all cross streams of 16 m to 42 m in width and provide a ballast deck…
