| 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. |
