It is a legal requirement under the Construction (design and management) Regulations 2015 that the principal contractor must take steps to prevent unauthorised access to the site.

Providing a safe and secure site for colleagues, visitors and our supply chain is fundamental to an inclusive and safe workplace. We must ensure that our sites are secure both during the working day and when unoccupied or out of hours.

  • Undertake a risk assessment to determine the level of security required. This should have been identified at tender stage.
  • Secure perimeter of the area to be taken over at earliest opportunity with a suitable fencing solution. This could be either Heras fencing or similar for short durations or a more permanent solution, e.g., timber hoarding. A temporary works design must be in place to assess the stability of the proposed solution.
  • Ensure segregated access points are in place for pedestrians and vehicles to limit people, plant interface, and these must be controlled by:
    • Vehicles: Barrier (automated/manual/concertina) and/or a gate person or security trained individual.
    • Pedestrians (including visitors): Gated entrance, or turnstiles where possible.
  • Appoint an individual to control the access points and prevent unauthorised access.
  • Ensure suitable security arrangements are in place to protect the site when unoccupied, preventing unauthorised access and ensuring all assets are secure, e.g., foot patrols, intrusion detection devices (These must comply with the Morgan Sindall Group IT Policies). The arrangements must include:
  • Provide suitable security lighting provision considering light pollution for neighbours and/or planning conditions.
  • If the compound/office is within a established secured facility e.g., a nuclear licenced site, security arrangements must align and link with any existing arrangements for the facility.
  • Installation of an automatic number plate recognition (ANPR) gate where there is a large volume of vehicle movements throughout the day.
  • Creation of ‘air locks’ or holding areas to reduce incursions/unauthorised access to the compound.
