A construction phase plan (CPP) is part of the process of mitigating risk and issues that may arise in construction projects. It helps the contractor prepare for correct health and safety procedures to be followed on site.

By creating a detailed document, the site should run more efficiently and be a safer environment for everyone. A robust construction phase plan is an essential component of CDM 2015 Regulations.
Construction Risks
Risks in construction tend to increase directly in proportion with the scale of work taking place.
| Due to legal changes brought in by CDM 2015, all projects require suitable Construction Phase Plans prepared by the principal contractor for both commercial and domestic projects. |
This means that while the refurbishment of a house may be less complex than building from scratch, there will still be issues that need to be planned for ahead of time.
The construction phase plan usually begins with a brief description of the works to be completed. If there are any unusual risks, handling hazardous substances, or working in constrained conditions, these will be highlighted.
The document will also give an overview of the planned sequence of works. These two parts are vital for helping unrelated trades remain vigilant and aware of issues that could emerge before or during their time on site.
In cases of significant hazards, the construction phase plan will also be supported by method statements and worker briefings. These ensure that all site workers are aware of high-risk activities, but also how they can play a part in removing the risks for themselves and others.
The format of worker briefings is also defined within the CPP document, as it relates to the chain of communication. Usually headed up by the site manager, each trade supervisor and subcontractor supervisor have a duty to ensure that the teams under their care are appropriately qualified and certified to work on-site, but equally that they are following appropriate safe construction practices.
| Clients need to ensure they are working with experienced contractors who are compliant and ensure CPP documentation is closely followed. Primarily this will protect everyone on site, but it also means that the construction process will be better managed. |
Site rules help to provide a clear standard that everyone can adhere to. These rules often refer to other statutory, professional, and guidance documents to capture a broad overview – but, also state explicitly the need for “all operatives to report daily to be recorded in the site attendance register”, the need for PPE, and the importance of the site being fenced, secure and locked when unoccupied.
When contractors are working with an external monitor or auditor, CPP documents will form a clear benchmark for reporting on whether good procedures are being followed on site.
Construction Phase Plan updates
The construction phase plan is a dynamic set of documents, for example, if a site worker is injured or new health risk is uncovered, these need to be logged within the accident register and the health and safety file. Steps also need to be put in place to ensure the incident doesn’t occur again.
The construction phase plan should be updated whenever new developments or information emerges; for example, if the plans change as the project develop or external factors emerge which may impact the health and safety of those working on site.
As is often the case with architectural projects, some design details may remain incomplete until after construction has begun. A contractor should adapt the documents as required throughout the project so that the work can continue to proceed safely and in line with best practice.
