A SYSTEM, A METHOD AND A COMPUTER PROGRAM FOR CONSTRUCTION PROGRESS MONITORING

A computer implemented method for construction progress monitoring uses a mobile device. The mobile device comprises a mobile processor. The mobile device further comprises a mobile memory and a scanner unit both functionally coupled to the mobile processor. In addition, the mobile device comprises a receiver and a sender both functionally coupled to the mobile memory. The method comprises receiving, using the receiver, at least a part of a building information model of a building to be constructed. The at least part of the building information model comprises a first plurality of model elements, each with a descriptor. The at least part of the building information model is stored to the mobile memory. The method further comprises acquiring, using the scanner unit, a spatial information of a construction site of the building to be constructed, and comparing, using the mobile processor, the spatial information and a model element of the first plurality to decide whether a section corresponding to the model element exists in the spatial information. If the section corresponding to the model element exists, the method further comprises sending, using the sender, at least part of the descriptor of the model element for updating a model of the construction site.
