The invention enables efficient continuous and fully automated construction progress monitoring in real time, inside and outside the building under construction, without additional work activities, as the wearable devices are installed on all work equipment contributing to the construction. It is a fully automated system that enables the acquisition of 3D data using wearable devices and to identify elements based on their geometry in the 3D digital model of the building. The wearable devices are equipped with a 3D scanner and other components, where the identification of the elements takes place in real time during construction, and a direct comparison between planned and actual execution is possible to provide an immediate insight into the status of the project.
