Bridges, tunnels and other road structures are presently designed to achieve their design life requirement of 100 years. This may not necessarily lead to a cost-effective outcome and all asset owners are seeking the lowest whole of life cycle cost…

The Infrastructure Asset management is facing critical demand and challenges in encountering the concerning issues pertaining to the existing bridges due to un-foreseen accidents. The emergency issues arising due to possible vandalism, low height…

Collecting, processing, and administering data from bridge inspections underpins bridge lifecycle management. Although, the inspection process and identification of material defects is well defined and documented, little guidance is given on systems…

Theoretical assessments of a bridge network to AS5100.7 identify many bridges operating at margins smaller than those embodied in AS 5100.7. The cost of strengthening these bridges is unpalatable and the consequences of restricting access are…

Roads and Maritime Services, New South Wales is responsible for managing over 5600 bridges and bridge size culverts, with a written down value of 12.5 billion and a replacement cost of 18.2 billion. Roads and Maritime bridge stock is the oldest and…

VicRoads manages a significant number of structures where access for inspection is difficult due to height, length and the obstacle being crossed

Steel in bridge construction in Australia has declined significantly over the last 40 years from around 25% of bridges to as low as 5% of bridges in recent years. The main reasons for this have been the proliferation of precast prestressed concrete…

Reliable live traffic data collection is crucial for effective pavement life prediction, fatigue estimation, vibration control, maintenance, and condition assessment of the bridge structures. Bridge weigh-in-motion (BWIM) is a technology utilising a…

At 1.76km long, the Rakaia River Bridge is the longest bridge in New Zealand. When combined with the Rangitata River Bridges (identical structural form), these structures comprise 223 spans and over 2.7km of reinforced concrete bridge on State…
