RR555 - Construction (Design and Management) Regulations 2007

This report provides a baseline for the future evaluation of the cost and effectiveness of the proposed revisions to the Construction (Design and Management) Regulations 1994 (CDM) that are planned to take effect in April 2007. It describes a study of the costs incurred, and attitudes held, by duty holders when complying with CDM 1994. A largescale survey of CDM duty holders was conducted to collect cost and attitudinal data. In-depth interviews with duty holders were also conducted to aid in developing the questionnaire and providing a context for its results. Costs were analysed by duty holder, type and size of project, and time spent on site. A key finding was that the cost of CDM compliance did not exceed 2% of the project value for any duty holder. Respondents were generally positive about the outcomes associated with CDM 1994, with bureaucracy indicated as a continuing problem area. Cost data were also collected on activities not required in CDM 1994 but proposed in CDM 2007. As some duty holders are already incurring costs for some of those activities, the net cost of CDM 2007 on them may be relatively small. Lessons learnt are identified and recommendations are included for the future evaluation of CDM 2007.
