Embedding reuse into infrastructure projects by carrying out ‘pre-redevelopment audits’

There is significant potential for large infrastructure projects with multiple demolition phases to kick-start a second-hand materials market and unlock a truly circular economy. Civil engineers are well-placed to lead this by carrying out reuse appraisals, commonly known in the buildings sector as ‘pre-redevelopment audits’. The paper sets current practice and emerging policies regarding reuse in the construction sector, then describes the steps for undertaking an effective audit. The aim is to assess and maximise the reuse and recovery of materials from the start, thereby helping to reduce the industry’s overall greenhouse gas emissions.
