The project concerns the 3D survey of a ten-story building structure in Syntagma, located on Panepistimiou and Kriezotou streets. The technical company CERS SA commissioned this project to us, as the new 5-star hotel of LAMPSA SA will be erected soon. We were asked for the topographic survey of the interior perimetrical walls of the building, photographic documentation of the steel structure and its installation site, as well as the geometric documentation of the systems of interest with photorealistic texture. Finally, with the production of an interactive virtual navigation using virtual reality glasses, the design team and the management were able to share rich visual material.
