CDM Regulations 2015
Recognise CDM roles, information flows, construction-phase coordination and the supervisor's contribution.
How to prepare for SSSTS
Connect each duty and hazard to the supervisor's workface sequence: check the task and RAMS, brief the team, establish controls, observe and intervene, then report and learn.
Core concepts
Concept 1
Client, designer, principal designer, contractor and principal contractor duties interlock across the project.
Exam cue: Name the CDM role before allocating a statutory duty.
Concept 2
Contractors plan, manage and monitor their work while the principal contractor coordinates the construction phase.
Exam cue: Check interfaces between trades, designs, sequencing and changing conditions.
Concept 3
Supervisors turn relevant pre-construction and construction-phase information into clear workface controls.
Exam cue: Feed workface concerns and changes back through the coordination route.
