How many scaffold frames do I need?
Short answer
Frame sets = bays along × levels up. With the SIMAQ A001 frame (1.75 m tall, 3 m bay), a 12 m front where you stand at 5 m takes 4 bays × 3 levels = 12 frame sets and 24 braces, plus screw jacks (or locking casters if it moves) on the first-level legs and gap-free platforms at each working level. Calculate it below with your dimensions.

Your scaffold
12 frame sets · 24 braces
4 bays of 3 m cover 12 m; 3 levels of 1.75 m put the platform at 5.25 m.
| Part | How many | Why |
|---|---|---|
| A001 scaffold frame set | 12 | 4 bays × 3 levels |
| A002 cross-brace | 24 | 2 per set |
| A003 screw jack | 10 | one per first-level leg |
| A004 platform (25 cm × 3 m) | — | Full width, no gaps, on 4 bays (each working level). Your advisor confirms how many fit across. |
| Guardrail and internal ladder | — | At each working level at height |
- Joined bays share frames: that's why jacks or casters are 2 × (bays + 1), not 4 per set. Your advisor adjusts the frame list so you don't overbuy.
- At height, tie the scaffold to the structure.
- P001 shoring props aren't scaffolding: if you're pouring a slab, count them separately.
How it's calculated
- Bays = front length ÷ 3 m (the A001 braced bay), rounded up.
- Levels = height you stand at ÷ 1.75 m (frame height), rounded up: the platform ends up at that height or a bit more.
- Frame sets = bays × levels; braces = 2 per set.
- Screw jacks (or casters, if mobile) = one per first-level leg; with joined bays, 2 × (bays + 1).
- Platforms: cover the full width on every bay of each working level.
Assumptions and sources
- 1.75 m frame height and 3 m bay.Source: SIMAQ A001 scaffold frame spec sheet.
- Frame sets = bays × levels, two braces per set, one jack or caster per leg.Source: SIMAQ School guide «How many scaffold frames do I need?».
- The height the screw jack adds isn't counted.Source: this tool's rule: the platform ends up a bit higher, never lower.
- How many 25 cm platforms fit across isn't calculated.Source: the sheet publishes the frame width, not the clear width between frames: your advisor confirms it.
Every result is a reference estimate. It doesn't replace a professional's design or supervision.
FAQ
How tall is a SIMAQ scaffold frame?
The A001 frame is 1.75 m tall and 1.55 m wide, with a 3 m bay with the X brace. Levels and bays are counted from those dimensions.
How many cross-braces does a frame set take?
Two per set, locked before going up a level. Without them the frame isn't rigid.
Screw jacks or casters?
Screw jacks to level a fixed scaffold on firm or uneven ground (never bricks or wedges). Locking casters if it has to move; brakes stay on while working.
Do shoring props count as scaffolding?
No. P001 props (2.20 to 4.00 m) hold formwork and temporary loads. If you're pouring a slab, count them separately.
