What?
- CDM 2015 places specific duties on every contractor working on a construction project, regardless of project size.
- A contractor is any business or person who carries out, manages, or controls construction work — this includes subcontractors.
- Contractors must plan, manage, and monitor their own work to ensure it is carried out without risk to health and safety.
- They must provide adequate supervision, instruction, and information to their workers for every task on the project.
- Contractors must ensure their workers have the skills, knowledge, training, and experience to carry out the work safely.
- They must cooperate with the principal contractor and other contractors to coordinate work and prevent conflicts between trades.
- Contractors must comply with the site rules and directions given by the principal contractor for the project.
- They must report anything they are aware of that is likely to endanger the health or safety of any person on site.
- Contractors must provide their workers with the information and training needed to carry out their work safely.
- Welfare facilities must be provided or arranged for their workers unless the principal contractor is providing them.
Why?
| Personal legal duty | Every contractor has individual legal duties under CDM — claiming ignorance of the law is not a defence against prosecution. |
| Competent workforce | Contractors must ensure their workers are trained and competent — sending unqualified workers to site is a criminal offence. |
| Cooperation | CDM requires contractors to work together — failure to cooperate creates the dangerous trade interface incidents that kill workers. |
