Last month, the Rottnest Island jetty collapsed, severely injuring a young boy and two women while they were on a fishing trip. Although serious injuries resulted, luckily no one was killed in this incident. This incident highlights the need for ongoing and thorough condition inspection/investigation of public infrastructure, particularly for aging assets and those in aggressive environments.
In this article, Ian Godson outlines the growing risk of corrosion caused deterioration to prestressed concrete elements and summarizes the investigation, repair and long term durability options for prestressed structures.
The use of Prestressed Concrete for construction of bridge, wharf and other civil structures expanded rapidly from the 1960’s onwards, due mainly to the increased spans and economy that it provided.
It's a 'picosecond' and it is also the measurement of pulse durations in the application of Ground Penetrating Radar (GPR)
Developed in the 1970’s, alongside great discoveries inventions such as the Cellular Phone and the Apple Computer, Ground Penetrating Radar (GPR) made significant advances through that decade.
ACA 2016, NZ
The Australiasian Corrosion Association (ACA) brings together representatives of diverse technical streams at an international meeting each year to embark on the quest of mutual understanding and support. ACA’s 2016 three-day conference held in Aotearoa, New Zealand hosted over 450 of world’s experts that fight corrosion on a daily basis.
Insights on maximising the longevity of the marine infrastructure.
As a part of the design plan for Webb Dock, Colin Trewern, a Senior Maritime Engineer at Jacobs, and our very own Dean Ferguson dived into making a case for durability amidst marine structures and surfaced with an award-winning paper for ‘Best Review’ at the Australasian Corrosion Association, 2016, hosted in New Zealand. One morning by the waterfront, we engaged these gentlemen in a conversation, learning about their findings and discussing the industry at large. We bring to you insights from their paper in an excerpt.
