Abstract [en]

Six railway bridges have been scanned using infrared scanning (IR), close range photogrammetry(CRP) and terrestrial laser scanning (TRS) to reconstruct point clouds and evaluate the potential ofthe technologies for building information modelling (BIM)- and assessment purposes. The resultsmay also help to improve bridge inspection routines. This is done by evaluating the accuracy andquality of the point clouds, time consumption, safety and traffic disturbance.Wireless Monitoring has been used in a demonstration project in Sweden. It consists of a basestation and nodes. The base station receives signals from the node antennas and transmits thesignals to the cloud. The nodes are equipped with strain gauges, crack opening devices,temperature sensors or other suitable sensors for the investigation purpose. Results from themethods and conclusions regarding further use will be presented
