Hoarding is a temporary structure of solid construction, erected around the perimeter of construction sites to shield them from view and prevent unauthorised access. It is an important component in ensuring health and safety, for site workers, visitors and the general public and can also be part of a site security system to prevent theft or vandalism.
Perimeter hoarding provides a system for controlled access. Turnstiles, security gates and guards can be used to ensure only authorised personnel can enter. In addition, hoarding might be used to separate different functions within a site, for example creating a barrier between traffic routes and pedestrians.
