The CDM Regulations don’t just apply to contractors and construction workers on sites, but to the whole project team. Clients, designers and contractors all have duties under CDM, at all stages of the project. From pre-construction, through to the construction, project completion and beyond.
According to the CDM Regulations, there are three stages to every construction project. Pre-Construction. Construction. And Post-Construction. And there are CDM duties to complete at each stage of the project. Things you need to do before work starts on site. Then things that need to happen during construction. And finally, things that need to take place after work is completed.
If you’re new to construction, or the CDM regulations, start with what is CDM in construction?
So let’s take a look at the 3 stages of CDM.
What is pre-construction?
Pre-construction is everything that happens on a construction project before you do any construction work. You might refer to this as the planning phase or project preparation, but in CDM, it’s known as pre-construction.
“pre-construction phase” means any period of time during which design or preparatory work is carried out for a project and may continue during the construction phase;

Interpretation But if the CDM regulations are focused on health and safety in construction, then that would just apply to the construction phase, right? What’s the pre-construction phase got to do with health and safety? Quite a lot, as it happens!
As with most things, with health and safety, preparation is key. And this is especially important in construction where you are bringing different people together, on a new site, with various hazards and risks. Each build and site is unique, and careful consideration of how the health and safety issues can be minimised at the pre-construction phase is vital to reduce health and safety headaches during construction.
This is why the CDM regulations pay so much attention to the pre-construction phase. Clients have duties at the pre-construction phase. Designers have duties at the pre-construction phase. Contractors have duties at the pre-construction phase. And the pre-construction phase is when the
principal designer and the principal contractor are appointed.
In fact, you can’t skimp on the pre-construction phase. The regulations clearly state that the client must allow enough time for the work to be carried out without risks to health and safety. This includes allowing sufficient time for all of the pre-construction duties to be carried out, like making appointments, carrying out design work, preparing the pre-construction information and the
construction phase plan.
The principal designer has overall responsibility for health and safety during the pre-construction phase, and other duty holders will work with them to comply with CDM.

The construction phase is the time when construction work is actually happening. At this point, you have your designs and plan of work, your construction phase plan in place and your team assembled. Everything is planned out, at least for the early stages of your project.
“construction phase” means the period of time beginning when construction work in a project starts and ending when construction work in that project is completed;

Interpretation This is the point in the project that you might think CDM really kicks in, but actually, most of the CDM duties should already be discharged by now, during the pre-construction phase. At the construction phase, the principal contractor has been appointed and the construction phase plan has been developed.
But this is also the time in the project when all that planning and preparation is put into practice. So important duties continue into the construction phase like organising contractors and coordinating their work, communication between duty holders if plans change or issues arise, securing the site and making sure that those on the site have had suitable inductions and are safe to work.
principal contractor has overall responsibility for health and safety during the construction phase, and other duty holders will work with them to comply with CDM.

There’s no specific definition (or even mention) of post-construction in the CDM regulations. But there are duties that must be carried out at or after project completion, so we refer to this as the post-construction phase.
Health and safety risks don’t stop when the work finished on site. Now the project is complete, people will start to use the structure and equipment installed. People will need to clean and maintain it. Eventually, it may need to be altered or demolished. There could be many health and safety risks in the future use of the structure. CDM acknowledges this, by requiring this health and safety information to be passed on to the client in what is known as
the CDM health and safety file
(10) At the end of the project, the principal designer, or where there is no principal designer the principal contractor, must pass the health and safety file to the client.
(7) If a client disposes of the client’s interest in the structure, the client complies with the duty in paragraph (5)(b)(iii) by providing the health and safety file to the person who acquires the client’s interest in the structure and ensuring that that person is aware of the nature and purpose of the file.
So at project completion, the health and safety file needs to be given to the client. And this should be kept by the client so that anyone carrying out future work will have the information they need to be able to plan and complete the work safely.
