Scaffold Loads – Dead + Live + Wind

Quick answer

Load check: scaffold self-weight ~0.4 kN/m² per lift, live load by duty class, and wind pressure 0.5-0.8 kN/m² on sheeted bays.

Figures are estimates from this calculator’s standard formula — adjust the inputs in the tool below for your exact number.

How the scaffold loads calculator works

Total = Self (0.4 × Lifts) + Live (Duty × Area) + Wind (0.6 kN/m² × Sheet Area)

This tool applies the formula Total = Self (0.4 × Lifts) + Live (Duty × Area) + Wind (0.6 kN/m² × Sheet Area) directly to the measurements you enter, so the result is an exact quantity rather than a rough guess. Because scaffold loads is priced and delivered per unit - cubic meters, square meters, bags or tonnes - a small measurement error multiplies across the entire order, which is why the calculation is worth doing properly. Worked example: A sheeted 7-bay scaffold, 4 lifts, medium duty: self 11 kN + live 38 + wind 29 - ties take the wind, legs take the rest. One note from practice: Add a 5-10% waste margin to scaffold loads before ordering. Enter the bay count, lifts, duty and sheeting, check the totals, then round up to the nearest whole bag, sheet or roll before you place the order.

  1. 1

    Measure the space

    Record the bay count, lifts, duty and sheeting at the widest and longest points.

  2. 2

    Enter the values

    Type the measurements into the calculator and select your units.

  3. 3

    Apply the formula

    The tool computes Total = Self (0.4 × Lifts) + Live (Duty × Area) + Wind (0.6 kN/m² × Sheet Area) for your inputs instantly.

  4. 4

    Add waste and order

    Review the total with a 5-10% margin and round up to whole units.

Use Cases

Slab reinforcement

Bar counts, laps and kg totals for scaffold loads mats.

Steel procurement

Convert scaffold loads lengths to tonnes for mill orders.

Plumbing rough-ins

Pipe runs and fitting allowances for scaffold loads layouts.

Common Mistakes

  • Weight from wrong diameter

  • Exceeding conduit fill

  • No lap splice allowance

FAQs

Self-weight of scaffolding?

About 0.4 kN/m² per lift - a 5-lift tower over 3 bays carries 5.4 kN before anyone climbs.

Wind load on sheeted scaffolds?

0.5-0.8 kN/m² pressure - sheeting turns the scaffold into a sail; add ties and never sheet the top lift alone.

Tie force per anchor?

Design ties for 2.5-6.2 kN each depending on substrate - block walls hold the low end, concrete the high.

Outrigger or tie - which when?

Tie to structure wherever it exists; outriggers (1.2 m) where facades forbid drilling - never both skipped.
