  1. What is the health and safety file under CDM 2015, and who is responsible for preparing it?

    Answer: A record of information useful for future construction, maintenance, or demolition work, prepared by the principal designer and passed to the client on completion

    The health and safety file (Regulation 12(5)) contains information relevant to future construction, maintenance, renovation, or demolition work. The principal designer prepares and reviews it during the project. On completion, it is passed to the client, who must keep it available for future use.

  2. Under CDM 2015, what duties does a contractor (not the principal contractor) have?

    Answer: Contractors must plan, manage, and monitor their own work, ensure workers are competent and supervised, provide welfare facilities (if not provided by others), and cooperate with the principal contractor

    Under CDM 2015 Regulation 15, contractors must plan, manage, and monitor their own work to ensure safety. They must ensure workers are competent, trained, and supervised. They must cooperate with the principal contractor, comply with the construction phase plan, and report to the principal contractor on safety matters.

  3. What is pre-construction information under CDM 2015, and who must provide it?

    Answer: Information about the project, site, and any existing hazards that designers and contractors need for planning, provided by the client

    Pre-construction information (Regulation 4) is provided by the client and includes details about the project, planning conditions, the site (ground conditions, existing services, contamination), existing structures (asbestos, structural issues), and any other information relevant to health and safety that designers and contractors need.

  4. How does CDM 2015 apply to domestic clients (homeowners)?

    Answer: Domestic clients have CDM duties, but in practice these are automatically transferred to the contractor or principal contractor unless the domestic client appoints a principal designer

    CDM 2015 applies to domestic projects, but domestic client duties are automatically transferred to the contractor (single contractor project) or principal contractor (multiple contractor project). Domestic clients can choose to appoint a principal designer, in which case the duty transfer differs.

  5. Under CDM 2015, what must a principal contractor do regarding worker consultation on health and safety?

    Answer: The principal contractor must make arrangements for consulting and engaging with workers and their representatives on health and safety matters

    Under CDM 2015 Regulation 14, the principal contractor must make and maintain arrangements for consulting and engaging with workers (including the self-employed) on health and safety matters. This includes consulting on risk assessments, safe systems of work, welfare, and emergency arrangements.

  6. What happens if a project starts with one contractor and then a second contractor is appointed?

    Answer: The client must appoint a principal contractor and principal designer as the project now involves more than one contractor

    When a project involves more than one contractor, CDM 2015 requires the client to appoint a principal designer and a principal contractor. If a single-contractor project becomes a multi-contractor project, these appointments must be made promptly to ensure proper coordination of health and safety.
