Building passports and digital twin
Make a digital twin (e.g. BIM model) of the building project to store and share quantitative and qualitative data, and to get quick feedback on design changes. Make material/ building passports of the materials and elements in the building and couple it to the digital twin. Storage of data can facilitate maintenance and reuse in the future.
When to take action?
Who can take action?
Design team, contractors, manufacturers, owners
Beginner expertise needed
Create a detailed digital file, including all technical datasheets of the materials, products and elements used.
Depending on the size of the project, it is ideal to use material and building passports or
Building Information Modelling (BIM).
Update the information throughout the life cycle of the building. Appoint a person responsible for this.
Consider how this can be included in the as-built file.
Developed design of the building project, quantitative and qualitative data on the project.
Structured storage of data, which can facilitate maintenance and reuse in the future.
