Facilitating circular site preparation; developing the instrument PrCiSi

The urge to strive for closed material loops is felt in the construction industry. However, before the built environment can be regarded as circular, not only the material usage in buildings, but also preparations taken on sites need to be circular. In this paper a new instrument is presented to help project leaders at municipalities and contractors to assess how circular their process of site preparation is. The instrument, by the name of PrCiSi, has been developed on basis of a literature study on sustainable material usage and interviews among stakeholders in this niche market. The instrument has been tested on the site preparation processes for the residential neighbourhoods Olstergaard and Noorder Koeslag in the municipality of Olst-Wijhe. Of course, there is still room for improvement and more test cases are welcomed, but three main subjects, namely materials, equipment and personnel, seem to form a proper basis. A large number of test cases might help us to further develop the scoring system. However, being convinced that we can cross a boundary here, we are happy to share with you the current status to inspire you to use and improve this instrument with us.
