This guidance is designed to enable construction clients to include more ambitious circular design and construction principles in project briefs for non-domestic built assets. This is achieved by addressing the common commercial obstacles that clients may encounter, and providing practical support and evidence to assist them in setting clear circular objectives for their construction projects. The guidance also aims to ensure that the construction supply chain can effectively deliver circular economy goals and that budget, project management, and timescale risks are all minimised and mitigated.
