The Construction (Design and Management) Regulations 2015 (CDM)
Everyone involved in a construction project has legal duties under CDM 2015. These ‘duty holders’ are defined as Client, Principal Designer, Principal Contractor, Designers, Contactors and Workers.
What are the CDM regulations?
The Construction (Design and Management) Regulations (CDM 2015) are the main set of regulations for managing the health, safety, and welfare of construction projects. CDM applies to all building and construction work and includes new build, demolition, refurbishment, extensions, conversions, repair, and maintenance.
What is the purpose of the CDM regulations?
CDM aims to improve health and safety in the industry by helping you to sensibly plan the work so the risks involved are managed from start to finish and ensure you have the right information about the risks and how they are being managed.
The CDM regulations apply to every construction project, even construction work that one might not consider to be a project, like maintenance activities. It does not matter what the duration of the work is, or the size of the task, if it is construction work then CDM applies.
