More than half of the annual waste generation in Germany results from construction and demolition activities. The high quality utilization and recycling of the resources contained therein is still in its infancy. Dismantling and demolition projects are usually carried out under great time and cost pressure. During project bidding and pre-planning, the inbuilt (raw) materials are estimated via existing documents and an inspection. But reliable and comparable data on the resource potential of a building are not determined.
The underlying vision of the project ResourceApp is a combination of hardware and software supporting the user during site inspections with as little additional information as possible to allow a reliable statement about the of raw material content and potentially anticipated pollutants in a building. A model-based deconstruction project planning should help to efficiently regain the recyclables into the material cycle. Within the project a software is developed that detects geometric structures and components in buildings such as walls, ceilings, windows, doors, electrical outlets or radiators. By linking this information with data from literature and standards it is possible to deduce occluded components such as wiring, piping or reinforcements and to calculates the inherent raw materials of the building.
The project partners create a building typology and prepare relevant construction information. Then simulateneously, selection and tests of possible hardware are performed and software is developed. The building geometries are to be detected with the aid of image- and feature-based recognition and followed by a 3D reconstruction of the building and its elements. The next step is to combine construction information and building geometries and to link it with a building inventory and subsequent deconstruction schedule and cost. The development of ResourceApp is accompanied by practical verifications during the dismantling of residential buildings. Finally, the possibilities to transfer the ResourceApp approach to other products and industries such as infrastructure or transport are examined.
