Description

This paper carries out a survey conducted among the construction agents in order to evaluate the effectiveness and viability of several best practice measures regarding construction and demolition waste (CDW) management in building rehabilitation works. This survey was developed considering that in rehabilitation works two well differentiated activities are carried out: those of the dismantling of the building (deconstruction activities) and those of the execution of the new construction (construction activities). Results of this survey show that among the highly rated best practices for the design phase “designing the building in order to help the recovery of the materials at the end of its use” can be highlighted, despite less than 25% of respondents usually implement this measure in their works. Moreover, according to BP during the construction phase, the results reveal that only 70% of respondents routinely implement the most valued measure “Hiring authorized companies for the management of CDW” and 60% the second “Respecting the manufacturer’s directions regarding the transport, collection and commissioning”.
