What a scaffold hoarding is
A hoarding is the temporary wall around a site. It keeps the public out, keeps the work in, marks the boundary and often carries the project's signage.
A scaffold-based hoarding uses a scaffold frame as its structure and fixes panels or sheeting to it. The frame can follow an irregular boundary, change height where needed and be extended or moved as the site changes.
The same approach is used for temporary screens, enclosures and event structures where a frame has to go up quickly and come down without leaving damage.
The frame
The hoarding frame is built from scaffold components — standards, ledgers and braces — set out along the boundary. On the site side it is braced back to resist being pushed over, and its base is either fixed, weighted or braced as the design requires.
Because a hoarding is usually freestanding rather than tied to a building, its stability comes from its own bracing, base and any ballast, and the design accounts for that.
The frame is also built so that panels fix securely to it at the spacing the panels need.
Panels, sheeting and wind
Panels or sheeting turn the frame into a solid face. That is the point of a hoarding — and also what makes wind its main design load, because a solid face catches wind along its whole length.
The design sets the frame, bracing and base for the height and exposure of the hoarding, and for any signage fixed to it. Adding height, signage or banners later is a change that is checked first.
Fixings are inspected regularly, because a loose panel in wind can become a hazard to the people the hoarding is meant to protect.
Gates and access behind
A hoarding needs openings: vehicle gates, pedestrian gates and any viewing or service points. These are framed so the hoarding stays stable around them and so gates can open and close safely.
Other trades often need to work behind the hoarding or along its inside face. The frame is planned so that access is not blocked, and so that bracing does not obstruct site routes.
Where the hoarding runs beside a footpath, its outer face is kept clear of projections that people could walk into.
Inspection, changes and removal
A hoarding is inspected while it stands — after high wind in particular — for loose panels, damaged fixings, movement at the base and anything that has been altered.
As the site changes, hoardings are often moved or extended. Each change is made by the team responsible for the hoarding and checked before it is left.
At the end of the job, panels come off before the frame is struck, and the boundary is made good. Scaffold-based hoardings and temporary structures are supplied and erected as part of the hoardings and events offer.
