Every contractor involved in a construction project has duties under CDM 2015.
The main duty of a contractor is to plan and manage construction work under their control so that it is carried out in a way that controls risks to health and safety.
A contractor may be an individual, a sole trader, a self-employed worker or a business who carries out, manages or controls construction work in connection with a business.
Anyone who directly engages construction workers or manages construction work is a contractor. This includes companies that use their own workforce to do construction work on their own premises.
