Incorporating knowledge on construction methods into automated progress monitoring techniques

The research conducted in this publication focuses on automated progress monitoring. The recording of the as-built state of a construction site is achieved by photogrammetric methods (e.g. UAVs) and compared to an as-planned (4D) BIM model. Comparison results of those two parts show that especially parts which were “under construction‿ are difficult to detect. The authors provide a method that uses the additional information on the construction methods provided by the respective construction elements including e.g. formwork or material colors. In conclusion, the overall detection rate of built elements and those that are currently under construction can be improved and therefore optimize the whole monitoring process.     «
