|Project||Load Testing for Tottenham Road Overbridge, Tottenham|
|Client||John Holland Rail|
|Project Value||< $100k|
|Project Overview||John Holland Rail (JHR) appointed JJR to carry out a Level 3 Inspection and Load Rating of Tottenham Overbridge (OBW32597A), in accordance with AS 5100 Australian Bridge Design Code and applicable JHR CRN standards, including:
Tottenham Overbridge is a three-span steel girder bridge, built in the 1910s with a timber deck, which was replaced with a reinforced concrete deck, and steel trestles with concrete footings and abutments.
|JJR Involvement||JJR carried out stationary and moving load tests of the bridge with temporarily fitted displacement and strain gauges. Output from the gauges was analysed using a combination of known, inferred, and assumed parameters with computer/mathematical models of the bridge. The load testing results and structural engineering assessments were delivered in a report to JHR.|
