Following the 2019 fires, the MEMORIST team, in collaboration with the company FARO, carried out an emergency operation to safeguard Notre-Dame on the instructions of the Lead Architectes in charge of the historical monuments, the regional directorate of cultural affairs (DRAC), the \u00cele-de-France conservatoire of historic monuments (CRMH), and the prefect of the \u00cele-de-France region. The operation involved conducting a precise 3D survey of the building in its post-fire state in a single day to assess the damage.<\/p>\n
Data acquired from these initial post-disaster 3D surveys can be compared with pre-fire data to provide useful information for reconstruction and ongoing investigations. The complete MEMORIST dataset will provide all trades with a reliable database of 3D measurements, images and technical documents relating to the cathedral, particularly the most severely damaged sections.<\/p>\n

Over the course of 25 years, MEMORIST has carried out several 3D surveys of the cathedral using laser scanning \u2013 lasergrammetry \u2013 and photogrammetry techniques. The assembled data has enabled the reconstruction of scans (point clouds) of the roof, the framework (the \u201cforest\u201d) and the spire \u2013 elements that were lost in the fire.<\/p>\n
For the \u201cforest\u201d, this comprises:<\/p>\n
For the cathedral as a whole:<\/p>\n

Restoring Notre-Dame will require a combination of traditional building techniques and modern, digital construction methods.<\/p>\n
Starting today, BIM committee of the French association of companies specialising in the restoration of historic monuments (GMH), comprising managers and staff from approved contractors, will begin work on the BIM model of Notre-Dame with the support of Autodesk.<\/p>\n
MEMORIST, a member of the GMH and its BIM committee, is coordinating the development of the cathedral\u2019s BIM model in collaboration with the consortium\u2019s trades and Autodesk.<\/p>\n
