Construction Phase Plan (CPP)

A Construction Phase Plan, or CPP, Is Required for all Construction Projects, No Matter the Size or Duration of the Project. CHAS Assists Contractors with Drawing up and Submitting CPP Plans.

Advice on Preparing a Construction Phase Plan

When to Prepare a CPP
All contractors undertaking a UK construction project of any size or duration are required to draw up a health and safety Construction Phase Plan (CPP) under the Construction (Design & Management) Regulations 2015 (CDM 2015) Regulation 12.

The CPP plan should be proportionate to the size, scope and complexity of the project and must be drawn up during the pre-construction phase before setting up a construction site.

Deciding Who Should Prepare a CPP
For single-contractor projects, it is the responsibility of the contractor to ensure the construction phase plan is drawn up, reviewed, updated and revised so that it remains effective throughout the project.

For projects involving more than one contractor, the principal contractor is responsible for ensuring that the CPP is appropriately drawn up and managed.

While the single or principal contractor is primarily responsible for CPP compliance, the principal designer must also ensure that they provide all relevant information in support of the plan.

What a CPP Should Contain
The CPP must set out the arrangements for securing health and safety on-site. It should take into account, where necessary, all industrial, commercial, domestic or transport-related activities taking place on the construction site.

The following information should be included:

1. The name of the person/contractor that the CPP is prepared for
2. The name and address of the client
3. Contact details of the designer/principal designer
4. A description of the project
5. Key dates for the project
6. Details of who else is on-site and their contact details
7. Details of the principal contractor
8. Arrangements for keeping site management and personnel updated
9. The arrangements for managing the work, including:
a) Health and safety targets
b) Site rules
c) Welfare arrangements
d) Site inductions
e) Arrangements for consultation with workforce/briefings, etc.
f) Fire and emergency arrangements

Where applicable, the CPP must include specific arrangements in relation to work that falls within one or more of the following types, as detailed within Schedule 3 of CDM 2015:

1. Work that puts workers at risk of burial under earthfalls, engulfment in swampland or falling from a height where the risk is particularly aggravated by the nature of the work or processes used or by the environment at the place of work or site
2. Work that puts workers at risk from chemical or biological substances constituting a particular danger to the safety or health of workers or involving a legal requirement for health monitoring
3. Work with ionising radiation requiring the designation of controlled or supervised areas under regulation 16 of the Ionising Radiations Regulations 1999
4. Work near high-voltage power lines
5. Work exposing workers to the risk of drowning
6. Work on wells, underground earthworks and tunnels
7. Work carried out by divers having a system of air supply
8. Work carried out by workers in caissons with a compressed air atmosphere
9. Work involving the use of explosives
10. Work involving the assembly or dismantling of heavy prefabricated components
