Research PaperDevelopment of new system for detection of bridges construction defects using terrestrial laser remote sensing technology

There are probable damages and defects happening throughout structure execution or transport and consignment. Defect experience in construction is precious and remarkable. This research work is a trial to develop an easy system to accomplish the most common tasks in the process of detection and monitoring of the as-built structure. However, assessment programmes involved cannot sufficiently detect and deal with defects that happen at construction process, as they are based on measurements at particular positions and periods, and are not included into full electronic techniques. Therefore there is an important requirement to always observe the construction developments to keep away from major rework prices and interruptions. This research represents an automated advance to register laser remote sensing data of as-built model, with BrIM (Bridge Information Model) for a constructed bridge. An experimental work is carried out to confirm the planned method for monitoring the structural defects through a case study was implemented in the design and inspection data in the Jacques Cartier Bridge in Canada. The outcomes demonstrate that the existing technique can be employed to sense the defected elements or structure imprecision fast and accurately.
