Key takeaways

Buildings can present a great number of possible risks both in construction and operation. There are many duties placed on those commissioning, designing, constructing and operating buildings to control those risks.

The Construction (Design and Management) Regulations (CDM regulations) 2015, in particular, are intended to ensure that health and safety issues are properly considered during a project’s development. They include general requirements that apply to all projects and additional duties that only apply to notifiable construction projects.

You can read a general introduction to health and safety here.

This hub does not cover the safety of buildings or fire safety. You can find out more about the safety of buildings and fire safety here.

CDM and why it matters

The Construction (Design and Management) Regulations 2015 (CDM 2015) are the UK’s primary framework for managing construction safety. The require that all dutyholders; clients, designers, contractors and workers, proactively manage health and safety throughout the construction lifecycle.

CDM embeds health and safety into every stage of construction, mandating clear roles, systematic risk management, collaboration, and documentation. It covering almost all projects, and CDM ensures safer worksites. Roles like principal designer and principal contractor play central parts in coordinating pre-construction planning, risk reduction, site safety, and welfare arrangements (Designing Buildings). Core duties include competency checks, risk assessments, pre-construction information, construction phase plans, and maintaining a health and safety file (Designing Buildings).

Other health and safety requirements.

Other health and safety requirements are set out in legislation such as the Building Regulations, the Health and safety at work etc Act, the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations and so on.

More specific regulations apply to activities such as working at height, lifting operations, noise and vibration, asbestos and manual handling and to equipment such as personal protective equipment (PPE).
