The CDM 2007 Regulations apply to all construction projects where people are at work. For further information see[domestic clients](http://www.hse.gov.uk/construction/cdm/faq/domestic.htm).

```
The Regulations are divided into five parts:

	Part 1 – application of the Regulations and definitions.

	Part 2 – general duties that apply to all construction projects.

	Part 3 – additional duties that only apply to notifiable construction projects, ie those lasting more than 30 days, or involving more than 500 person days of construction work.

	Part 4 – practical requirements that apply to all construction sites.

	Part 5 – transitional arrangements and revocations.
