Under the Construction (Design and Management) Regulations 2015 (CDM 2015), the Principal Contractor holds statutory responsibility for planning, managing, monitoring, and coordinating health and safety throughout the construction phase.
1. Construction Phase Plan (CPP) Timing & Substance
Regulation 12 requires the Principal Contractor to draw up a project-specific Construction Phase Plan before setting up the construction site. Generic or boilerplate plans remain the primary citation in HSE enforcement notices. The CPP must address high-risk site activities, traffic management, emergency arrangements, and welfare provision.
2. Technical RAMS Review & Subcontractor Vetting
Principal Contractors must rigorously evaluate subcontractor Risk Assessments and Method Statements prior to site mobilisation. A tick-box review without assessing task-specific controls breaches Regulation 13 duties to ensure cooperation and coordination across dutyholders.
3. The Role of the Principal Designer Interface
Close collaboration between the Principal Designer and Principal Contractor ensures pre-construction information (PCI) transitions seamlessly into temporary works designs and safe working methods on site.
