Unit NG1: Management of health and safety
Unit NGC 2: Risk Assessment

Managing contractors effectively

Where clients use contractors there are shared responsibilities for ensuring the health and safety of client and contractor workforces and anyone else who may be affected by the work. If not properly managed, accidents are likely.

Planning and co-ordination of contracted work

A contractor’s employees may possibly be at a greater risk than the client’s employee whilst working on the client’s site due to:

  • unfamiliarity with the client’s site
  • unfamiliarity with the client’s site rules and procedures
  • often contractors are used for high risk activities
  • lack of appropriate training
  • poor supervision

Health and safety requirements should be written into the contract for the work, clearly defining the responsibilities of each party.

Construction (Design and Management) Regulations 2015

The Construction (Design and Management) Regulations 2015 (CDM) aims to integrate health and safety into the management of a construction project and for everyone involved to work together.

All projects (even those with just a single contractor) require…

  • Workers with the right skills, knowledge, training and experience
  • Contractors providing appropriate supervision, instruction and information
  • A written construction phase plan

Projects where more than one contractor is involved, in addition to the main requirements for all projects, require…

  • a principal designer
  • a principal contractor
  • a health and safety file

HSE Notification of construction projects

A project is notifiable to the HSE if the construction work on a construction site is scheduled to:

  • last longer than 30 working days and have more than 20 workers working simultaneously at any point in the project, or
  • exceed 500 person days

Where a project is notifiable, the client must give notice in writing to the HSE as soon as is practicable before the construction phase begins.

The easiest way to notify any project is to use the electronic notification form.

The client must ensure that an up-to-date copy of the notice is displayed in the construction site office, so it is accessible to anyone working on the site and can be easily understood. The form must be periodically updated where necessary.
