Construction (Design and Management) Regulations 2015 - Frequently asked questions

Notifications - F10s

When is a construction project 'notifiable'?

A construction project is notifiable if the construction work is expected to:

  • last longer than 30 working days and have more than 20 workers working at the same time at any point on the project or
  • exceed 500 person days

Find out how to notify projects, and complete the F10 notification form.


Does the 30 working days/500 person days on site include weekends, bank holidays etc?

Every day on which construction work is likely to be carried out should be counted, even if the work on that day is of a short duration. This includes holidays and weekends.

Who should notify a project?

The client has the duty to notify a construction project. In practice however, the client may ask someone else to notify on their behalf.

Maintenance

Does CDM 2015 apply to all maintenance work?

No. The definition of construction work has not changed under CDM 2015. The application to maintenance work remains the same as it was under CDM 2007.

Principal Designer (PD)

I was a CDM co-ordinator under CDM 2007. Can I now work as a principal designer (PD)?

No, not necessarily. To work as a PD, you must be a designer:

  • You might be an architect, consulting engineer, quantity surveyor or anyone who specifies and alters designs as part of their work
  • You might also be a contractor/builder, commercial client, tradesperson or anyone who carries out design work, or arranges for or instructs people under your control to do so

You must have the right mix of skills, knowledge, experience and (if an organisation) organisational capability to allow you to carry out all of the functions and responsibilities of a PD for the project in hand, and be in control of the pre-construction phase.


I was an architect/designer on the planning and Building Regulations stages of a project and I am no longer involved with the project. Who will take on the role of principal designer (PD)?

The client has the duty to appoint the PD. If you are no longer involved with the project, the client must appoint another PD. You will still be responsible for the design decisions you made in preparing the original plans. The new PD must then take responsibility for any design decisions made following their appointment.

I am a client, can I take on the Principal Designer (PD) role?

Yes. You can choose to take on the PD role yourself. If you do you must have the skills, knowledge, experience and (if an organisation) organisational capability, to carry out all the functions and responsibilities of the PD.

Small builder

I am a general builder who only works on small-scale commercial and domestic projects, will CDM 2015 affect me?

Yes. CDM 2015 applies to all construction work including domestic projects.

You will have different responsibilities depending on whether you are (for example):

For more information, please go to Are you a small builder…

Construction Phase Plan (CPP)

As a general builder do I need a CPP for any construction work I do?

Yes. If you are the only contractor or the principal contractor (PC), you must draw up a CPP.  However, it should be proportionate to the size and scale of the job.

A simple plan before the work starts is usually enough to show that you have thought about health and safety.

If you are a contractor working for a PC, it is the PC who must draw up the CPP.

To help you draw up a CPP for small-scale projects, go to the template CPP, or the CDM Wizard, a free-to-download smartphone app produced by the Construction Industry Training Board (CITB).

Self-build

I want to build my own house, does CDM 2015 apply to me?

To find out, go to The Self Build Portal.

Miscellaneous

Can I carry out the role of more than one CDM duty holder on a project?

Yes. Whether you are an individual or an organisation (client, designer, principal designer, contractor or principal contractor), you can carry out the role of more than one duty holder.  You must have the skills, knowledge, experience and (if an organisation) the organisational capability to carry out all of the functions and responsibilities of each role in a way that secures health and safety.
