What you must do

30 compliance obligations under this legislation — 30 can result in imprisonment.

Appointments 1

Appoint a principal designer and principal contractor in writing

2 years imprisonment

If your construction project will involve more than one contractor, you must formally appoint a principal designer to lead the pre‑construction design work and a principal contractor to manage the build. The appointments have to be in writing, made as soon as practicable and definitely before the construction phase starts. If you don’t make these appointments you will have to take on their duties yourself.

Client (commissioning work) s.5 HSE When more than one contractor is or is likely to be working …

Equipment and safety 1

Provide and maintain fire detection and fighting equipment

2 years imprisonment

On any construction site where a fire risk exists, you must supply appropriate fire‑fighting equipment and fire‑detection/alarm systems, locate them correctly and keep them in good working order. The equipment must be regularly tested, clearly sign‑posted and easily reachable, and all workers must be trained on how to use it. No one should carry out work that could cause a fire until they have been given the required instruction.

Contractor s.32 HSE If a fire risk is present on the construction site

Inspections 1

Inspect excavations before each shift and after any incident

2 years imprisonment

Whenever you are carrying out construction work in a trench or pit, you must take all reasonable steps to stop the excavation collapsing or material falling. A competent person must check the excavation at the start of every shift, after anything that could affect its stability, and after any material falls. Work can only continue if that inspector is satisfied the site is safe.

Contractor s.22 HSE when carrying out construction work in an excavated area that requires supports …

Management duties 25

Arrange and test emergency procedures on construction sites

2 years imprisonment

You must put in place suitable emergency plans for any foreseeable incidents that could endanger people on your construction site, including evacuation steps. Everyone who might be affected needs to know the procedures, and the plans must be regularly tested, for example by carrying out drills.

Contractor s.30 HSE If a foreseeable emergency could affect health or safety on the construction …

Comply with Part 4 health and safety requirements on construction sites

2 years imprisonment

If you are a contractor carrying out construction work, or a domestic client who controls how that work is carried out, you must follow all the health and safety rules set out in Part 4 of the CDM Regulations for the parts of the project you control. In practice this means checking the regulations and making sure your site, workers and processes meet those standards.

Employer s.16 HSE When you are a contractor or domestic client with control over construction …

Consult and engage workers on health and safety

2 years imprisonment

If you are the principal contractor on a construction site, you must set up systems that allow you and the workers to work together on health, safety and welfare. You need to consult workers (or their reps) early about any matters that could affect their safety, and let them see and copy any safety information you hold, unless an exemption applies. This helps keep everyone informed and reduces the risk of accidents.

Contractor s.14 HSE When acting as the principal contractor on a construction project

Control vehicle movement and ensure safe use on site

2 years imprisonment

If you use any vehicle on a construction site you must stop it from moving unintentionally, operate and load it safely, keep it away from excavations, water or edges, and give clear warnings to anyone at risk. Workers may only ride or stay on a vehicle in the safe place provided for that purpose.

Contractor s.28 HSE when a vehicle is used for construction work on the site

Ensure cofferdams and caissons are safe before use

2 years imprisonment

If your site uses a cofferdam or caisson, you must make sure it is properly designed, fitted with escape routes and kept in good condition. A competent person must inspect it at the start of every shift and after any incident that could affect its stability, and only allow work if they are satisfied it is safe. Work must stop until any problems are fixed.

Contractor s.23 HSE When using a cofferdam or caisson for construction work

Ensure competence, cooperation and clear communication on construction projects

2 years imprisonment

If you are the client commissioning construction work, you must make sure any designer or contractor you hire has the right skills, knowledge, experience and organisational capacity, check this before you appoint them, work together with all parties on site, and give any safety information or instructions in a clear, understandable form as soon as practicable. Doing this helps protect the health and safety of everyone who could be affected by the project.

Client (commissioning work) s.8 HSE When you appoint a designer or contractor for a construction project

Ensure safe traffic routes on construction sites

2 years imprisonment

You must organise the site so that pedestrians and vehicles can move without risk.

Regular checks and proper maintenance are also required.

Ensure stability of structures and temporary works

2 years imprisonment

When you carry out construction work you must make sure that any building or structure you’re working on won’t collapse, even if it becomes temporarily weak. Any temporary supports, buttresses or structures you put in place must be designed, installed and maintained to carry the loads they are likely to face, and they must only be used for the purpose they were designed for. This duty runs for the whole time you are working on the structure.

Contractor s.19 HSE When carrying out construction work that could affect the stability of a …

Incorporate health & safety into designs and share risk information

2 years imprisonment

As a designer you must make sure your designs remove, or as far as reasonably practicable reduce, any foreseeable health and safety risks.

Designer s.9 HSE When preparing or modifying a design for a construction project

Maintain good order, cleanliness and security on construction sites

2 years imprisonment

You must keep every part of your construction site tidy and reasonably clean, and make sure the site boundaries are clearly marked with signs or fencing where needed. Any timber or material with protruding nails must not be used, and any such dangerous material must be removed. Doing this helps prevent injuries and avoids enforcement action by the HSE.

Contractor s.18 HSE

Manage health and safety of construction projects

2 years imprisonment

If you commission any construction work, you must set up and keep up a complete health‑and‑safety management system for the whole project. This means allocating enough time and resources, providing designers and contractors with all pre‑construction information, making sure a construction phase plan and a health‑and‑safety file are produced and kept up to date, and checking that the principal designer and principal contractor fulfil their own duties. You also need to keep reviewing these arrangements for the whole duration of the project and hand over the health‑and‑safety file if you sell the building.

Client (commissioning work) s.4 HSE When you act as the client commissioning a construction project

Manage safety of energy distribution installations on site

2 years imprisonment

If your construction work is near overhead power cables or underground services, you must make sure those installations are safely positioned, regularly inspected and clearly marked. Where a risk exists you must either move the cables, isolate/earth them, or put up suitable warnings and protective measures. You cannot carry out work that could damage an underground service unless you have taken all reasonably practicable steps to prevent the risk.

Contractor s.25 HSE When construction work involves or is adjacent to overhead electric power cables …

Plan and document demolition/dismantling safely

2 years imprisonment

If you are carrying out demolition or dismantling, you must organise the work so that danger is avoided, or reduced as far as reasonably practicable.

You must keep records to show you have done all of this.

Contractor s.15 HSE When acting as a contractor on a construction project

Contractor s.13 HSE When you act as the principal contractor on a construction project

Plan, manage and monitor health & safety in pre‑construction

2 years imprisonment

Provide adequate fresh air and ventilation on construction sites

2 years imprisonment

This is an ongoing requirement for the whole time work is being carried out.

Contractor s.33 HSE

Provide adequate lighting on construction sites

2 years imprisonment

You must make sure the construction site, its entry ways and any traffic routes are lit sufficiently for safety, using natural light where reasonably practicable. Any artificial lights must not distort or hide safety signs, and you need backup lighting in case the main lights fail.

Provide and keep clear emergency routes and exits

Provide reasonable indoor temperature and outdoor weather protection

2 years imprisonment

You must make sure that any indoor work area on your construction site is kept at a temperature that is reasonable for the work being carried out, and that outdoor sites are arranged to protect workers from bad weather.
