A system combining BIM and 3D scanning has been deployed at the Mogador theatre in Paris by Equans France and Engie Lab Crigen. The aim is to identify areas of thermal discomfort, improve the comfort of the 1,600 spectators and, ultimately, make energy savings. A project led by Bruno Gobe, Director of Operational Development at Axima Maintenance Technique (Equans) and Victoria Bogdanova, Digitalization and Services Expert at Engie Lab Crigen. I have been in charge of scanning day documentation and of corporate portraits of experts at work.
