3D Construction Passport for CIRCL

The circularity (reuseability of its materials) of ABN AMRO's CIRCL building will be permanently recorded in a Construction Passport. Using a new digital tool this new pavilion at the Zuidas in Amsterdam will be mapped out in 3D. Core components will be described and materials listed for future reference. This development brings The Netherlands one step closer to their “Netherlands Circular in 2050” ambition.

The digital tool, we helped develop, was presented Friday 23 June 2017 during a suppliers meeting in CIRCL. The tool will contain information about the elements, components and materials inside the building. Referred to as “a maintenance booklet” by architect Hans Hammink, it details the performance of each of the components and how they could be re-used later on. “It is important that even 20 years from now you can find out exactly what materials a building is made of,” says Hammink.

The ABN AMRO CIRCL pavilion is a special project. The wish to construct it with circularity in mind emerged while building it. Inside the bank, people became more and more aware of the principle of circularity when they saw the destruction of materials involved with the demolition of old bank buildings. It seemed a waste of potentially useful materials. ABN AMRO Real Estate Manager Rudolf Scholtens recounts how they tried, unsuccessfully, to sell the marble facing from the FORTIS building on the Rokin in Amsterdam via Dutch online auction site Marktplaats. To be disassembled by the buyer...

Now this may not have been the best place to offer it but at the time there was no alternative. As the re-use of resources (known as urban mining) becomes more popular, however there is a need for more structure. Urban mining involves finding your raw materials in the “city” rather than sourcing new materials from mines, managed woodlands or farming. There is a definite shift happening from a linear to a circular economy and suppliers will soon be generating their revenues from new as well as “circular” commodities.

One of the aims of this meeting was to involve suppliers in this new approach to sourcing. Circularity requires a change in the way things are done. Through workshops participants put together a list of the types of information that should be included in the “passport”: component performance, warranties, mounting and assembly information and much more. And much was said about the user-friendliness of the tool itself. All insights gained from the workshops will be incorporated into future releases of the tool.

De Architekten Cie., in cooperation with Rendemint and CAD & Company, will continue to develop the 3D tool. It is our aim to make the tool available for other buildings (current and new) as well.
