CDM 2015: managing health and safety in construction
Updated 2026
The Construction (Design and Management) Regulations 2015 place duties on clients, principal designers and principal contractors to plan, manage and monitor construction work safely. Accurate, real-time records of who is on site — inducted, authorised and accounted for — directly support the principal contractor's duties for site induction, access control and emergency procedures.

Who does what under CDM 2015
CDM 2015 defines duty holders and their responsibilities across the lifecycle of a project. The principal contractor plans, manages and monitors the construction phase and coordinates health and safety, including site inductions and access.
Keeping the right people out of the wrong areas — and knowing who is on site at any moment — is central to discharging these duties.
Induction, access and evacuation
A site induction ensures workers understand the hazards and rules before they start. The Salvus Network can enforce that only inducted, authorised workers enter controlled areas, and logs time on site automatically for compliance and payroll.
During an evacuation, the same network produces a live head count at muster points — replacing clipboard roll-calls that are slow and hard to audit on a busy construction site.

Frequently asked questions
Does CDM require electronic site records?+
CDM does not mandate a specific system, but principal contractors must plan, manage and monitor the construction phase. Accurate electronic records of induction, access and mustering make that demonstrable.
