CDM Services

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

• Last longer than 30 days
• Involve more than 500 person days of construction work

The 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.
