On all projects clients will need to:

• Check competence and resources of all appointees
• Ensure there are suitable management arrangements for the project welfare facilities
• Allow sufficient time and resources for all stages
• Provide pre-construction information to designers and contractors

Where projects are notifiable under CDM 2007, clients must also:  

• Appoint a CDM co-ordinator
• Appoint a principal contractor
• Make sure that construction work does not start unless a construction phase plan is in place and there are adequate welfare facilities on site
• Provide information relating to the health and safety file to the CDM co-ordinator
• Retain and provide access to the health and safety file
