Scan to BIM for the Semi-Automated Generation of a Material Passport for an Existing Building
Year: 2020
Type: conference-paper
Abstract: The construction sector has a large negative impact on the environment due to its wasteful treatment of raw materials.To minimize the raw materials consumption, increasing recycling rates through reusing or recycling materials in existing stocks is of utmost importance.However, the main obstacle in the recycling of existing building stocks is the lack of information about materials incorporated in buildings.This work presents the ongoing research within the multidisciplinary research project SCI_BIM, which received funding by the Austrian federal ministry of transport, innovation and technology.Within this paper, the semi-automated generation of an as-built BIM-Model for an existing building as well as the generation of a Material Passport (MP) is tested.In order to obtain the geometry and material information, laser scanners (geometry) and a Ground Penetrating Radar (GPR, for materials) are used.Thereby, first, a semi-automated BIM-Model is generated from the point cloud, which was obtained from the laser scans.Finally, the material information obtained from the GPR is integrated into the BIM-Model for the compilation of the MP.First results show that the generation of the MP for the use case is possible, but confronted with manual steps, such as integrating material information from different sources (e.g.analysis of demolition experts).The results of this paper should serve as a basis for the creation of a secondary raw materials cadastre in order to enable recycling of valuable materials, thus supporting the achievement of the EU goals 20-20-20.
