What is a Construction Phase Plan (CPP)?

A Construction Phase Plan is a mandatory document that outlines health and safety arrangements, site rules, and specific control measures for managing risks during construction work. It serves as a comprehensive framework that must be completed before any construction begins, regardless of project size. Having a suitable construction phase plan is essential for compliance and safety.

Who is responsible for creating the Construction Phase Plan?

For projects with multiple contractors, the Principal Contractor is responsible for creating and maintaining the CPP. For smaller projects with only one contractor, that contractor becomes responsible for developing the plan before work commences. When there is more than one contractor involved, the Principal Contractor is responsible for creating the plan.

What are the key components of a Construction Phase Plan?

The key components include project description, scope of work, management team structure, health and safety control measures, site logistics (access points, traffic management), hazardous substance procedures, emergency protocols, and waste management procedures.

  • Lifting operations: It is crucial to include lifting operations in the Construction Phase Plan to ensure site safety. Proper planning and control measures for lifting operations help minimize risks associated with various construction activities, ensuring the safety and health of all personnel on site.

How does a Construction Phase Plan differ from RAMS?

While both documents address safety, a CPP provides a broader framework for managing all aspects of site safety and logistics throughout the project lifecycle. RAMS (Risk Assessments & Method Statements) are more specific documents focusing on individual tasks or activities. A Construction Phase Plan also identifies potential risks and outlines measures to manage them.

What are the legal requirements for a Construction Phase Plan?

Under the UK’s CDM Regulations 2015, every construction project must have a written CPP before work begins. The plan must detail health and safety arrangements, be accessible on-site, and undergo regular reviews to maintain compliance. The plan must also be detailed enough to ensure compliance with CDM regulations.

Who needs access to the Construction Phase Plan?

The CPP must be accessible to all project team members, including contractors, workers, and site supervisors. It should be readily available on-site and communicated effectively to ensure everyone understands their roles and responsibilities. The plan must be shared with every contractor working on the project.

How detailed should a Construction Phase Plan be?

The level of detail depends on project size and complexity. Small projects need basic documentation, medium projects require detailed risk assessments, and large projects demand comprehensive management systems with extensive documentation. Larger projects necessitate a more detailed Construction Phase Plan to address the increased complexity and requirements.
