When does CDM 2007 (Construction, Design and Management Regulations 2007) apply to a project?

The CDM 2007 Regulations apply to most common building, civil engineering and engineering construction work. You must notify HSE of the site if the construction work is expected to either:

• last longer than 30 days; or
• involve more than 500 person days of construction work;

HSE should be notified in writing before construction work starts; you can use form F10. Your notification should be sent to the HSE office nearest to the proposed site.

Further information on CDM 2007 is available on HSE's construction section.
