The flowchart below provides an indication of the different influences and drivers in the supply chain for new build.
In summary, the drivers shown in the flowchart are as follows:
- External: policy, legislation, public opinion.
- Internal: where the different players in the supply chain influence one another.

It is recognised that the complexities of different construction contracts (Design & Build, Traditional etc) will result in some differences to the drivers shown. For example, a traditional construction project, may result in the client appointing the design team through a Professional Service Agreement (terms of engagement), accompanied by a Briefing Document. The
ICE Demolition Protocol would then be adopted through this agreement/document.
