Bridge Scanning Survey & Monitoring
Due to the high elevations and span distances, it was decided the best means of supplying the deliverables was to use laser scanning for the bridge underdeck and to carry out conventional total station surveys of the bridge decks, the bridge trusses and approach roads.
A high level of accuracy was required within the survey control network otherwise it would be imposible to join the individual laser scans.
In 2014, we were asked to resurvey the historic Namoi River bridge at Manilla to check if there had been any movement since the earlier survey. We now undertake regular surveys of the bridge to monitor its movement.
