CDM Regulations 2015

(CDM - Construction Design and Management)


We have experience of being Principal Contractor under larger type contracts. The Regulations actually apply to all contracts but where required, (due to project size / duration / man hours / work type) a notification via a F10 to the Health & Safety Executive (HSE) will be necessary.


These Regulations also apply to larger domestic works .

Generally, the notification to the HSE is required relating to any works in the following circumstances :

If work is scheduled to :


  • Last longer than 30 working days and to have more than 20 workers working simultaneously at any point in the project


  • OR exceeds 500 person days (ie a week for one person will equal 5 person days)


Such notifiable contracts are thus reasonably large for typical domestic works.

The former CDM-Coordinator role has been replaced by Principal Designer or Principal Contractor.

The new CDM Regulations impose duties on domestic clients as well as commercial clients, although domestic client duties will normally be transferred to the principal contractor/contractor, or, if the client wishes, to the principal designer. (ie say architect, surveyor or building designer.)

As Principal Contractor, we would prepare a Construction Phase Plan prior to the works commencing. This would illustrate and describe the known and potential Risks of the project. These would be addressed by Risk Assessments and Method Statements detailing how the works would be planned, managed and undertaken in a safe manner.

We can advise further on a specific project.
