Frame Scaffold Material Takeoff
Frames, cross braces, planks, and base plates for a frame-scaffold run off the bay layout and lifts.
Example
You enter
- Scaffold run length (ft) 40
- Bay / cross-brace length (ft) 7
- Frame levels high (count) 3
- Planks per bay platform (count) 4
You get
- Bays 6
- Frames (end frames) 21
- Cross braces 36
- Planks 24
- Base plates 14
Details, formula, and sources
bays = ceil(run / bay length); frames = (bays+1) x lifts; braces = 2 x bays x lifts; base plates = (bays+1) x 2. A 40 ft run on 7 ft bays, three lifts high, is 6 bays - 21 frames, 36 braces, 24 planks, and 14 base plates. Guardrails, ties, screw jacks, and access are taken off separately; a competent person designs the erection.
bays = ceil(run_length_ft / bay_length_ft); frames = (bays + 1) x lifts; braces = 2 x bays x lifts; planks = bays x planks_per_bay; base_plates = (bays + 1) x 2.
Frame-scaffold takeoff geometry by name (bays from the run, frames/braces from the bays and lifts); first-principles count arithmetic.
The takeoff is public quantity-survey geometry for a single-width frame run; the erection design comes from a competent person.
Estimate. AHJ and licensed professional govern.
