BRIDGES & MARINES STRUCTURES
It would seem strange to consider bridges and Marine structures as the same, but we consider jetties to be long bridges and we apply the same techniques to both with a combination of Mod-Shock and DBTS tests.
The bridge DBTS system was initiated in late 80’s and first applied to a large contract testing 120 bridges for Davy British rail for a UK funded up-grade of 150kms of railway line between Jakarta and Merak, the gate-way to Sumatra in Indonesia.
After this initial success we embarked on a joint study with Vic roads and others which led to the DBTS paper ”DYNAMIC BRIDGE TESTING SYSTEM (DBTS) FOR THE EVALUATION OF DEFECTS & LOAD CARRYING CAPACITY OF IN-SERVICE BRIDGES".
This was presented to a MICE conference in Singapore and is still the leading paper on our DBTS system for the testing of bridges
Since acceptance of our techniques for bridge testing we have completed over 1,600 bridges mainly in Australia, but also in other parts of the world, particularly in Asia. We illustrate with photographs some of the large contracts, but the largest one after the Indonesian project was the 79 bridges, we tested on behalf of Tamworth regional Council and another 100 bridges all part of the NSW scheme “Future roads”.
To give a fuller picture of the bridge testing go to “Rehabilitation of bridges the Integrity way” for more in depth details of our system.
The transition into testing jetties and piers was gradual , but the first large project was for the tanker jetty in Port Welshpool forGippsland ports with the testing of a 0.6 kilometer timber jetty.
After this jetty we progressed to all types of jetties and piers and have tested once again possibly over 100 major jetties and once again illustrate some of these projects with photographs. Possibly the largest of these projects which has been a four year programme to date was the testing of the jetties of the naval dockyards in Portsmouth, Uk on behalf of BAE systems and the Ministry of Defence. These projects are on -going with still further jetties to be tested.
For this project we also calculated the berthing capacity of the jetties so allowing the largest ship ever to dock in Portsmouth to safely dock at one of the jetties we tested without mishap.
In Australia we don’t have such large jetties, but we still test a large variety of piers and jetties using the system, which has proven to save millions of dollars on a number of projects as we give actual loading values and not guesswork values.
