Construction products can pose a potential risk to the environment and health due to their pollutant content or release of pollutants. This qualitative product information is not mapped in life cycle assessments and has not yet been systematically included in the BIM environment. In contrast, needs analyses among manufacturers and users show a high demand for this environmentally relevant product information in the digital building model. Normative standards for product information management and product data templates over the building life cycle, such as ISO 19650-1 and ISO 23387, were developed in 2019 and have so far only been used in proprietary systems in isolated cases.
The BIMpeco project is developing requirements and data structures for the digital information management of environmentally relevant product data. This data is to be managed and documented in the Common Data Environment (CDE, collaborative BIM environment for all - including non-graphical - information). The transfer of information along the supply chain, continuous specification of information requirements and quality assurance of the data ensure transparency and knowledge about the environmentally relevant properties over the entire life cycle of the building. Building on existing and new standards and methods, for the first time a basis for life cycle and supply chain product information management of the environmentally relevant properties of building products and building services components in the Common Data Environment is being created.
The central project result is an attribute model and data templates for recording and structuring environmentally relevant product information on building products and building services components (compliant with ISO 23387). Workflows and standards are developed for the integration of this product information into the tendering, awarding and invoicing process and into the Common Data Environment (compliant with ISO 19650-1). The project results will be tested on the basis of case studies using exemplary product data sheets and scenarios.
