CDM Regulations – A Rough Guide

What is CDM?

The Construction Design Management (CDM) Regulations cover the management of health, safety and welfare on construction projects, which includes some event sites.


The regulations break down the roles of different stakeholders, and provides specific information to each group detailing their responsibilities.


When does CDM happen?

Anyone who is having or undertaking construction and building work will have health and safety responsibilities to consider before starting work.

  • Clients, designers, contractors and others involved with construction work all have duties under the Construction (Design and Management) Regulations 2015 (CDM 2015)
  • Under CDM 2015, certain construction work must be notified to the Health and Safety Executive (HSE)


Who is involved?

The stakeholders outlined in CDM regulations are:

  • Client: the person for whom a project is carried out.
  • Principal Designer : designer with control over the pre-construction phase of the project. They are appointed by the client.
  • Designer: organization or individual who prepares or modifies a design for a construction project, or arranges for or instructs some else to do so.
  • Principal contractor: organization or individual who coordinates the work of the construction phase of the project involving more than one contractor, so that it is carried out in a way that secures health and safety.
  • Contractor: anyone who directly employs of engages construction workers or manages construction. A contractor can be an individual. Sole trader, self-employed worker or a business that carries out, manages or controls construction work as part of their business.


What are my duties?

Most of Jongor Hire’s customers will fall under the principal contractor category. As such, their duties are:

  • Plan, manage, monitor and coordinate the construction phase plan
  • Estimate the time required to complete the project
  • Take into account the general principals of prevention
  • Organise and facilitate cooperation between contractors
  • Comply with all health and safety legal requirements
  • Provide a suitable site induction
  • Review, update and complete the health and safety file, if the principal designer’s appointment finishes before the end of the event.


What are Jongor’s duties?

Jongor Hire can operate as a contractor or as principal contractor. Our Event Team have completed the Site Managers Safety Training Scheme, meaning they are qualified to undertake any role in the CDM structure.


Why is CDM important?

  • Those who create the risks are responsible for managing them. As such, risk control must be followed when making design decisions. Event projects should be designed so that they can be constructed safely, used safely and dismantled safely.
  • Compliance in Health and Safety has significantly increased with employers having a more greater obligation than ever. With on average 40 work related deaths due to construction work each year, it is now a requirement to protect workers during outdoor work. Designers are expected to manage occupational health risks.


CDM regulations will be mandatory on many event sites. Should you have any queries regarding how Jongor Hire can help you comply with CDM regulations, please don’t hesitate to call and ask our friendly team today.
