How much scaffolding do I need for a house?

The amount follows from the wall lengths, the height and the scaffold system. Here is the method, and the numbers ScaFix's engine gives for three example buildings.

The short answer

For ScaFix's example house (11.4 m × 5.3 m, eaves 4.5 m), scaffolding all four walls takes 33.4 m of scaffold in 12 bays with 2 deck levels. With Layher Blitz that is 287 pieces in all and about 203 m² of scaffold.

How to work it out

Measure every wall that needs scaffold: its length, and its height to the eaves (on a gable wall, up to the ridge).
Divide each wall's length by the system's bay length and round up. That is the number of bays; the corners need bays of their own.
Divide the working height by the lift height (usually 2 m). That gives the deck levels; the top deck sits just below the eaves.
Every bay needs standards (or frames), ledgers, decks, guardrails and toe boards on each deck level, plus base jacks, braces and wall ties.
Add the access: ladders through hatch decks, or a stair tower.
Count the pieces for the system you use: the same wall gives very different counts with different systems, as the tables show.

Three example buildings, computed by ScaFix

Every number below comes from ScaFix's engine, the same one as in the app, for buildings ScaFix made up itself. The scaffold goes all round each building. The tables show totals only; the full parts list for your own walls is in the app.

Why the systems give different numbers

Frame systems (such as Layher Blitz, Plettac SL or Jamax) use one prefabricated frame at each bay end, so they need fewer pieces.
Modular systems (such as Layher Allround, PERI UP or HAKI Universal) build every bay from separate standards and ledgers: more pieces, but they follow any shape.
A system with shorter bays needs more bays, and so more pieces, on the same wall.
A stair tower adds many pieces compared with ladders through hatch decks.

What the numbers do not include

Where the wall ties go: their number follows the system's tie rule, but the positions must be checked against the manufacturer's assembly instructions.
Nets, sheeting, weather protection, hoists and transport.

Questions and answers

How many bays does a scaffold for a house need?

Take each wall's length, divide it by the bay length and round up; the corners need bays of their own. All round ScaFix's example house (11.4 m × 5.3 m) that gives 12 bays with Layher Blitz.

How many scaffold parts does a house need?

It depends most on the system. For the example house (11.4 m × 5.3 m, eaves 4.5 m) ScaFix counts 287 pieces with Layher Blitz, 457 pieces with Layher Allround and 553 pieces with PERI UP.

How many square metres of scaffold does a house need?

Roughly the length all round times the height from the ground to the top of the scaffold. For the example house that is about 203 m² with Layher Blitz.

How many lifts does a scaffold need?

One deck level for about every 2 m of height, with the top deck just below the eaves. The example house gets 2 deck levels (the top one at 4.5 m); the 12.5 m block gets 6.

Can I work out the scaffold for my own house?

Yes. In ScaFix you enter the walls or import a PDF drawing, choose one of the scaffold systems, and get the scaffold in 3D with bays, lifts and the parts list. The result is a planning aid, not a structural calculation.
