Built2Spec is a European Project within Horizon 2020 that integrates innovative solutions for monitoring construction sites to reduce existing gap between project and actual performance.
3D reconstruction of the building is an effective tool both for assessing the correspondence between designed and built and for quantifying the actual improvement of work in progress.
For this purpose, B2S developed an advanced methodology based on the reconstruction of a Point Cloud by using rapid and competitive technologies with respect to traditional ones as, for instance, drones that are employed for the external survey of buildings.
Once the Point Cloud is generated, it can be finally compared with the BIM project (for highlighting discrepancies between the initial work stage) and with a previous stage (for quantifying the Work Progress).
