What Is a Construction Phase Plan?
A Construction Phase Plan (CPP) is a document required under CDM 2015 Regulation 12 that sets out how the construction phase will be managed safely. The principal contractor must prepare the CPP before the construction phase begins and update it throughout the project.
When Is a CPP Required?
A CPP is required for every construction project — not just notifiable projects. For projects with only one contractor, the contractor prepares a simple CPP. For projects with more than one contractor (or where the client has appointed a Principal Designer), a more comprehensive CPP is required. The CPP must be prepared before the construction phase begins and available on site throughout the project.
What Should a CPP Include?
- Project description, location, and programme
- Client and duty holder details — Principal Designer, Principal Contractor, and other appointments
- Site rules and access arrangements
- Welfare provisions — toilets, washing facilities, rest area, changing facilities
- Significant risks and control arrangements
- Management arrangements for health and safety on site
- Emergency procedures — fire, first aid, environmental, and incident response
- Traffic management and pedestrian/plant segregation
- Arrangements for coordinating and communicating with subcontractors
How Does a CPP Relate to RAMS?
The CPP is a project-level document setting the health and safety framework for the whole construction phase. RAMS are task-level documents that sit within that framework: each subcontractor’s RAMS must be consistent with the CPP site rules and management arrangements. The CPP identifies significant project risks; the RAMS identify the specific controls for each trade activity.
