Materials passport and BIM link for timber in construction

Against a backdrop of environmental crisis, the construction sector is a major consumer of raw materials and producer of waste. It is therefore the subject of a number of studies and initiatives aimed at getting it to adopt a circular economy approach. In particular, information relating to construction materials is crucial throughout a building's life cycle. Defining and maintaining this information through ‘materials passports’ (MPs) offers a wealth of opportunities, particularly in relation to Building Information Modeling (BIM) practices. But it has to be said that the definition of these BIM MPs and their implementation are still in their infancy, and are fraught with difficulties. This article analyses the scientific literature on PM BIM. It identifies the current implementations of PM BIM and their difficulties, highlighting the importance of questioning the structuring and content of the PM. This article identifies the potential but also the possible blockages in the use of PM BIM with a view to supporting the definition of future research directions.
