A construction phase plan (CPP) is a required document for all construction sites and should be proportional to the size or duration of the project. Today, we will explore what a Construction Phase Plan is, its key elements, and why it’s so important for business success.

What is a Construction Phase Plan?

A Construction Phase Plan (CPP) is a vital Health & Safety document used to ensure that construction projects are carried out in a safe and compliant manner. As part of schedule 3 of the Construction (Design & Management) (CDM) Regulations 2015, the CPP outlines the safety arrangements, site rules, and specific precautions required for managing risks on-site. This includes identifying hazards such as working near high-voltage power lines, operating heavy machinery, or dealing with hazardous materials.

The information within a Construction Phase Plan must be tailored to the specific tasks and risks associated with the project. It is not a one-size-fits-all document. Instead, it should reflect the unique conditions of the site and the work being carried out. This includes referencing details from the pre-construction information plan, which provides essential background on site-specific health and safety risks, such as the location of existing structures or potential environmental hazards.

Do I need a Construction Phase Plan?

Under the Construction (Design & Management) (CDM) Regulations 2015, if you are the sole contractor or the principal contractor for a construction project, you are legally required to create a Construction Phase Plan (CPP). The level of detail required in the plan will depend on the size, complexity, and duration of the project.

For smaller projects, the Construction Phase Plan may not need to be as detailed as it would for a large-scale construction site. However, even for smaller projects, it’s important to have clear evidence that Health & Safety measures have been properly considered and coordinated. This includes making sure that safety arrangements are in place and communicated effectively to all members of the project team, from contractors to subcontractors.

Who is responsible for the Construction Phase Plan?

The main coordinator of the Construction Phase Plan will be the contractor or the designated principal contractorif there is more than one on-site.

However, as this is a legally required document, the responsibility for its production also falls to the client. The principal designer and designers working on the project will also be responsible for providing all the relevant information which the contractor will need to create an exhaustive CPP.

Therefore, though the principal contractor is responsible for the management of the work, there must be cooperation between the key site decision-makers for the document to be completed in full.

What should a Construction Phase Plan include?

A CPP should include the following details below, along with any other information relevant to the specific project it is being drafted for.

  1. The name of the contractor the plan is being prepared for.
  2. The client’s name and address.
  3. The principal designer’s contact information.
  4. The principal contractor’s details.
  5. Description of the project for example:
    • location of the project
    • timescales, including key dates
    • nature of the work
  6. Project team members and their details, including contact information.
  7. Details of site management arrangements, such as site meetings and safety information to keep personnel updated.
  8. Information relating to the management of work including:
    • Health & Safety goals and health monitoring methods
    • Considerations for workers and the public, for example during access to and egress from the site
    • Site rules – e.g. emergency procedures and specific safety arrangements
    • Welfare facilities – personal hygiene facilities must be in place before work can start
    • Site inductions
    • Consultations and briefings with the workforce and project team
    • Emergency arrangements, including first aid and fire safety procedures

When is a Construction Phase Plan prepared?

Work on a construction project cannot begin until the Construction Phase Plan (CPP) is prepared, meaning the principal contractor must ensure it is completed before any construction activities start. However, the CPP typically contains answers to problems identified in the pre-construction information plan. As such, the contractor may need to complete this first before drawing up the CPP.

When should a Construction Phase Plan be updated?

Depending on the nature of the work, some details of the project may not be certain or finalised when work is due to begin. Because of this, the Construction Phase Plan should be treated as a live document, regularly updated as new information becomes available or details previously unclear are clarified and assessed. While smaller projects may not require frequent updates, the CPP should be revised if there are any significant changes to the plans or schedule to ensure it remains accurate and reflects the current scope of work.

How a Construction Phase Plan ties into CDM Regulations

The Construction (Design and Management) Regulations 2015 aims to improve the safety of those who work in construction, no matter your role.

In 2015, CDM regulations were updated and the Construction Phase Plan was made a requirement for all construction projects and not just larger-scale projects. This includes:

  • Installing a kitchen or bathroom
  • Structural alterations, eg chimney breast removal
  • Roofing work, including dormer windows
  • Extension or loft conversion

Requirements of Schedule 3 of the CDM Regulations 2015:

Schedule 3 of the CDM 2015 also requires the CPP to include specific consideration for works relating to a few safety risks, including:

  • Burial under earthfall, falling from a height or engulfment in swampland, particularly where the risk is more considerable due to the nature of the work or the methods being used at the site
  • Considerable risk from hazardous substances and chemicals
  • Exposure to ionising radiations where the designation of controlled and supervised areas is a requirement of regulation 16 of the Ionising Radiations Regulations 1999
  • Risk from high voltage power lines
  • Drowning risks
  • Risks presented by working on earthworks and underground tunnels
  • Risks to divers with air supply systems
  • Work carried out in caissons with a compressed air atmosphere
  • The use of explosives
  • Work such as lifting operations related to the assembly or dismantling of heavy prefabricated components
