"How much scaffolding does this building need?" It is the first question in every enquiry. The answer is a two-step calculation: first, how many square metres the façade is; then, how many components that area means in the chosen system. Both can be worked out at a desk, as long as they are done in order.
01Façade area first
Scaffolding is measured in square metres: façade length × working height. On a building with four elevations, each one is listed separately and corners are counted once.
The most common mistake on site is deducting door and window openings. The scaffold stands in front of the façade; it passes in front of the windows too. Openings do not reduce the material, so they are not deducted.
02The system decides the bay lengths
The square metres stay the same, but the parts list changes with the system:
- In the flanged (wedge-lock) system bay lengths are 70, 103, 153, 203, 253 and 303 cm. The façade length is covered by a combination of these; the right combination shrinks both the material and the freight.
- In the H-frame system frames are set at 150, 200 and 250 cm spacings; one module covers roughly 5 m² of façade.
We compared which system suits which façade in a separate article: flanged or H-frame?
03From square metres to a parts list
Once the system and the grid are fixed, the take-off becomes a parts list. A typical façade scaffolding bill includes:
- Standards (verticals) and ledgers
- Braces (not in every bay, but in the pattern the design shows)
- Platforms and the transoms under them
- Base jacks and base plates
- Guardrails, intermediate rails and toe boards
- Ties (anchors) to the façade
You do not have to do this conversion yourself; send us the measurements and we will produce the parts list together with the system proposal.
04The items most often left out
When two quotations differ, the gap is usually not price but missing items. The most commonly forgotten:
- Ties: a façade scaffold is not a free-standing structure; its overturning safety comes from the connections.
- Stair access: a scaffold without an access route is not finished; climbing the braces is not a solution.
- Toe boards: the part that stops a dropped hand tool; always the last to be remembered.
- Safety netting: not part of the take-off, but part of site safety.
05How the take-off sets the price
Scaffolding is discussed per square metre, but what actually drives cost is tonnage: the same area weighs differently depending on the system and the bay layout. In freight the driver is volume: which bay lengths are chosen changes how many trucks or containers the order fills. We wrote about how that works for export orders here.
So for a sound quotation, the façade dimensions, storey height and the elevation drawing if available are enough. The rest (system proposal, parts list and loading plan) is our job.
