A clear guide to construction activities covered by CDM 2007, helping you manage health and safety risks effectively.
Construction projects can be messy, complicated affairs. From site clearance to demolition, there’s a lot going on, and the Construction (Design and Management) Regulations 2007, or CDM 2007, set out rules to keep things safe. These regulations cover a wide range of activities, not just the obvious building work. They include site preparation, installation of services, maintenance, and even dismantling structures. Understanding exactly what’s covered helps everyone involved—from clients to contractors—stay on the right side of the law and avoid accidents. This article breaks down what construction activities fall under CDM 2007, why it matters, and what duties come with it.
Key Takeaway
- CDM 2007 covers almost all construction activities from initial site work to demolition and maintenance.
- Notifiable projects lasting over 30 days or involving 500 person-days require extra duties like appointing a CDM coordinator. (1)
- The regulations assign specific responsibilities to clients, designers, and contractors to manage health and safety risks. (2)
Construction Design and Management: The Scope of CDM 2007 Regulations
Construction, by its nature, involves many moving parts. The CDM 2007 regulations were introduced to bring some order to this chaos, focusing on health and safety throughout the project lifecycle. The rules apply to a broad spectrum of activities, ensuring that risks are managed from the moment the site is cleared to when the last brick is laid—or even when the building is taken down years later.
Building Work Under CDM
The obvious starting point is building work. This includes new construction, alteration, conversion, and fitting out. Whether it’s a small extension or a large commercial block, these activities fall squarely under CDM 2007. The regulations require proper planning and risk assessments before work begins, which helps prevent accidents that might otherwise happen due to poor preparation.
Civil Engineering and Engineering Construction Work
Civil engineering projects—think roads, bridges, tunnels—are also covered. These projects often involve heavy machinery, deep excavations, and complex logistics, making health and safety management crucial. Similarly, engineering construction work, including mechanical and electrical installations, is included. This means everything from installing hydraulic systems to telecommunications wiring must comply with CDM 2007.
Demolition, Dismantling, and Decommissioning
Taking structures down is as risky as building them up. Demolition activities, dismantling of structures, and decommissioning are all covered. (3) This includes the removal of waste and debris resulting from these processes. Proper planning here is vital to protect workers and the public from falling materials, dust, and other hazards.
Site Preparation and Clearance
Before any building can start, the site needs to be prepared. This might involve clearing vegetation, leveling the ground, or removing old structures. CDM 2007 covers these activities too, recognizing that risks exist even before construction begins. Poor site preparation can lead to accidents later on, so managing this phase carefully is essential.
Renovation, Repair, and Maintenance
Construction work doesn’t stop once a building is finished. Renovation, refurbishment, repair, upkeep, and even cleaning involving high-pressure water or corrosive substances are included under CDM 2007. This ensures that health and safety standards are maintained throughout the building’s life, not just during initial construction.
Installation and Commissioning of Building Services
The regulations also cover the installation, commissioning, maintenance, repair, or removal of services fixed within or to a structure. This includes mechanical, electrical, gas, hydraulic, telecommunications, and computer systems. These activities often require specialist knowledge and carry their own risks, so CDM 2007 ensures they’re properly managed.
Assembly and Disassembly of Prefabricated Elements
Prefabrication is common in modern construction. The assembly and disassembly of prefabricated elements on site fall under CDM 2007. This covers everything from walls and floors to entire modules. Handling these large components safely requires careful coordination and risk assessment.
Notifiable vs Non-Notifiable Construction Projects
CDM 2007 makes a distinction between notifiable and non-notifiable projects. This classification affects the level of duties imposed.
What Makes a Project Notifiable?
A project is notifiable if construction work lasts longer than 30 days or involves more than 500 person-days of work. These thresholds trigger additional legal requirements. For example, clients must appoint a CDM coordinator and a principal contractor. (4) They also need to ensure a Construction Phase Plan is in place and a Health and Safety File is prepared.
Duties for Notifiable Projects
Notifiable projects require more detailed planning and coordination. The CDM coordinator oversees health and safety during the design and planning phase, ensuring risks are identified and managed early. The principal contractor takes charge during construction, coordinating activities on site to maintain safety standards.
Non-Notifiable Projects
Smaller projects that don’t meet the thresholds still fall under CDM 2007 but with fewer formal requirements. Even so, basic duties like risk assessments and ensuring worker competence remain. It’s a common misconception that small jobs are exempt from health and safety rules—they’re not.
Who Has Responsibilities Under CDM 2007?
The regulations assign duties to several key players in a construction project. Each has a role to play in managing risks and ensuring safety.
Client Duties
Clients are responsible for making sure the project is set up safely from the start. This means appointing competent people, providing adequate resources, and ensuring that health and safety is considered throughout the project lifecycle.
Designer Responsibilities
Designers must eliminate or reduce risks through their designs. They need to provide information about any remaining risks to those who will build or maintain the structure. This is called design risk assessment and is crucial for preventing accidents caused by design flaws.
Contractor Duties
Contractors are responsible for managing health and safety during construction. This includes preparing the Construction Phase Plan, coordinating with other contractors, and ensuring workers are trained and competent.
CDM Coordinator Role
The CDM coordinator acts as a bridge between clients, designers, and contractors. They help ensure that health and safety is integrated into project planning and execution. Their duties include advising on legal compliance and facilitating cooperation among all parties.
Managing Risks on Construction Sites
Risk management is the backbone of CDM 2007. Identifying hazards early and controlling them reduces accidents and injuries.
Construction Risk Management Practices
Risk assessments must be carried out for all activities, from site preparation to demolition. These assessments identify potential hazards like unstable structures, hazardous substances, or working at height. Control measures are then put in place, such as scaffolding, protective equipment, or safe work procedures.
Construction Site Safety and Security
Maintaining a safe site means controlling access, securing materials and equipment, and ensuring clear communication among workers. Site security also prevents unauthorized entry, reducing the risk of accidents or theft.
Construction Site Welfare Facilities
Providing adequate welfare facilities—like toilets, washing areas, and rest spaces—is part of CDM 2007. These might seem minor, but they affect worker wellbeing and productivity, which in turn impacts safety.
Documentation and Planning Under CDM 2007
Paperwork might not be glamorous but it’s essential for compliance and safety.
Construction Phase Plan
This document outlines how health and safety will be managed during the construction phase. It includes details on risk control, emergency procedures, and coordination between contractors.
Health and Safety File
The Health and Safety File is prepared at the end of the project and handed to the client. It contains information needed for future maintenance or demolition, such as design risks and materials used.
Construction Project Notifications
For notifiable projects, the client must notify the Health and Safety Executive (HSE) before work starts. This triggers inspections and oversight to ensure compliance.
Activities Excluded from CDM 2007
Not everything on a construction site falls under CDM 2007. Minor works lasting less than 30 days or involving fewer than 500 person-hours are typically excluded. Certain domestic client projects and maintenance or removal of insulation unless part of a larger project are also outside the scope.
Practical Advice for Construction Professionals
Understanding what activities CDM 2007 covers is just the start. Here are some practical steps to keep projects safe and compliant.
- Always assess whether a project is notifiable and fulfill the additional duties if it is.
- Appoint competent people early, including a CDM coordinator for notifiable projects.
- Keep risk assessments up to date and involve all stakeholders in safety planning.
- Maintain clear and accessible documentation like Construction Phase Plans and Health and Safety Files.
- Ensure workers receive proper training and understand their safety roles.
- Regularly inspect the site and update safety measures as the project evolves.
- Don’t overlook smaller tasks like site clearance or cleaning; they carry risks too.
- Communicate openly about hazards and encourage a culture where safety concerns can be raised without fear.
