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.

This guide is based on sound industry practice and will particularly help small businesses and organisations deliver building and construction projects in a way that prevents injury and ill health.

There are six guides: one for each of the five duty holders under CDM and an additional one for workers.

This guide focusses on Principal Designers.

This industry guidance has been produced by members of CONIAC (Construction Industry Advisory Committee).
