Abstract:The building construction industry is responsible for 60 percent of the raw materials extracted from the lithosphere. Raw materials are scarce but limited and must therefore be well documented so that they remain unlimited. With the help of the material passport, materials get an identity, which means that they can never disappear in anonymity as waste. In this research the central question was how a material passport in Madaster can be generated from a BIM-model and be kept up-to-date during the operation and maintenance phase of a building. Madaster is a platform were material passport can be generated from BIM-models. To study this question first the requirements of Madaster were compared to the specifications of BIM modeling standards. Secondly, data about the process of generating a material passport is collected with the help of interviews. The respondents of the interviews are employees of companies that have experience with generating a material passport in Madaster and an employee of Madaster. The results of this study showed that the input BIM-models for Madaster often lack data which means they do not meet the requirements of Madaster. Generating a material passport in Madaster from a BIMmodel should be an automatic process. However, there are some manually steps that needs to be taken. This study provides some optimization strategies to reduce the manually work needed to create a material passport and keep it up-to-date. Currently there is no motivation to keep a material passport up-to-date during the operation and maintenance phase. Certification and legislation of a material passport could increase the use of a material passport and make it common practice. Firstly, from this research appeared to generate a material passport in Madaster the BIM-models need to meet the requirements of Madaster which is often not the case. Secondly from this study appeared to keep a material passport up-to-date it is important that there are motivations such as tax deductions or legislations to motivate property owners to keep the material passport up-to-date. Generating material passport from the data in the BIM-models will give the materials in a building an identity, which means the materials cannot be treated as waste. In this way BIM will contribute to a more sustainable and circular construction industry.
