CDM 2015 Documents Explained

CDM stands for the Construction (Design & Management) Regulations 2015. The latest version of the CDM regulations has been in force for over a decade and applies to all construction projects in Great Britain.

There are three crucial documents required for construction projects under CDM 2015.

• The pre-construction information.
• The construction phase plan.
• The health and safety file.

These three documents contain the important health and safety information required at each stage of a construction project.

There were some slight tweaks between the previous 2007 version and the current 2015 version of the regulations. But these documents should sound familiar. The pre-construction information, the construction phase plan, and the health and safety file were also needed under the previous version of CDM.

But when you need them - and who is responsible for producing them - well, that has changed.

So even if you have been familiar with CDM for many years, it's worth a quick refresh to make sure you are up to speed with the latest CDM document requirements.

To simplify, let's look at each document individually.

The Pre-Construction Information

When is it required?
The pre-construction phase.

Who's responsible?
The client.

📑 Create your document with our quick and easy online pre-construction information CDM template.

The pre-construction information document is required on every construction project. No matter how big, small, short or long.

This document is the first CDM document to be produced, and it's required at the very start of the project. And by the start of the project, we mean before you pick a contractor, before the designs are done, and way before construction work starts.

It's not just contractors that need this information to work safely, but designers too. The information included in the pre-construction information is needed by all designers and contractors planning the work. It will tell them where hazards are on site, and what unusual risks or constraints might impact the design and the construction work.

Ultimately, the responsibility for providing this information falls on the client. It is one of the CDM 2015 client duties.

(4) A client must provide pre-construction information as soon as is practicable to every designer and contractor appointed, or being considered for appointment, to the project.

The client will often have help putting the pre-construction information together.

When a principal designer has been appointed by the client, the principal designer will assist the client in the development of the pre-construction information.

You can find out more about the appointments a client must make, and client duties under CDM, in the free CDM duty holder guide for clients.

The pre-construction information should be available on every construction project. It's a legal requirement under CDM for projects of all sizes. No matter how small, and regardless of whether or not a principal designer is appointed. This was also the case under the old 2007 version of the CDM regulations; however, the CDM coordinator (now extinct) would assist the client. Now, this is one of the duties of the principal designer instead.

The pre-construction information includes information about the project, arrangements, and the client brief. It should also include health and safety information about hazards on the site. This will be information like surveys and plans already in the client's possession or obtained by the client.

It may also include information from any existing health and safety file.

The Construction Phase Plan

When is it required?
For the construction phase.

Who's responsible?
The principal contractor.

📑 Create your document with our quick and easy online construction phase plan CDM template.

Like the pre-construction information, the construction phase plan is also required on every construction project.

Previously, under the old 2007 version of the CDM regulations, the construction phase plan was only required on notifiable projects. Under the 2015 regulations, things have changed. The construction phase plan must now be produced for any project, regardless of size or duration.

Every construction project must have a construction phase plan.

The principal contractor is responsible for producing the construction phase plan unless there is only one contractor involved in the project, in which case, the sole contractor must create it.

You can use the information provided in the pre-construction information to help develop the construction phase plan. The hazards present on the site will need to be addressed, along with arrangements for managing health and safety during the project.

The construction phase plan must be developed before work starts on site. This document contains information on how health and safety will be managed on the site throughout the construction phase.

You might not know all your plans from the start, for example, later activities in the project. And, of course, things can change during the project. So you can revise and add information to the construction phase plan document as you progress through the project. E.g. if new trades start and additional activities or arrangements need to be addressed.

(4) Throughout the project the principal contractor must ensure that the construction phase plan is appropriately reviewed, updated and revised from time to time so that it continues to be sufficient to ensure that construction work is carried out, so far as is reasonably practicable, without risks to health or safety.

The Health and Safety File

When is it required?
Project completion.

Who's responsible?
The principal designer.

📑 Create your document with our quick and easy online health and safety file CDM template.

The health and safety file is the final document to be produced under CDM. This document gets handed over to the client on project completion for them to keep. It contains health and safety information needed for future use, cleaning and maintenance of the building or structure.

While the health and safety file is handed over on project completion, it shouldn't be confused with the O&M manual, as it is a CDM-specific health and safety document.

Unlike the other two documents covered in this post, the health and safety file isn't required on every construction project. It must be produced on any project with more than one contractor (including subcontractors).

This is whenever there is a principal designer appointed since the principal designer must be appointed on any project with more than one contractor.

So, if you need a principal designer, you'll need a health and safety file too.

It is the principal designer's duty to develop the health and safety file. But not alone. They will produce the file with information gathered from the project team.

The principal designer should start preparing the file during the pre-construction phase. The file will then be developed throughout the project and handed over to the client on completion.

Find out more about what needs to be included in CDM Health And Safety File Contents (What You Should Include).

(5) During the pre-construction phase, the principal designer must prepare a health and safety file appropriate to the characteristics of the project which must contain information relating to the project which is likely to be needed during any subsequent project to ensure the health and safety of any person.

The principal contractor, other contractors and designers all need to provide relevant information to be included in the health and safety file.

On some projects, the principal designer's appointment ends before project completion. In these cases, the file passes over to the principal contractor, who must then complete the file and hand it over to the client on completion.
