Scaffolding Calculator
Calculate scaffolding quantities for construction projects. Estimates standards, ledgers, transoms, platforms, ties, and total weight for tube & fitting or system scaffolds.
Perimeter: 100 m | Facade Area: 1500 m²
Bay spacing: 2m | Lift height: 2m
| Class | Capacity |
|---|---|
| Light Duty (0.75 kN/m²) | 0.75 kN/m² |
| Medium Duty (1.5 kN/m²) | 1.5 kN/m² |
| Heavy Duty (2.0 kN/m²) | 2 kN/m² |
| Special Duty (3.0 kN/m²) | 3 kN/m² |
- Scaffolding must be designed by competent person
- Weekly inspection required per BS EN 12811
- Tag system required for inspection status
- Ties assumed at about 4 m vertical × 4 m horizontal (1 per 16 m²); sheeted or exposed scaffolds need closer ties per TG20 or a scaffold design

- Scaffold must be inspected before first use and after any alterations
- Competent scaffolder required for erection and dismantling
- Ladder access bays should be at maximum 30m intervals
Notes:
- Quantities are estimates for budgeting purposes
- Actual design must be done by scaffolding designer
- Add 10-15% contingency for couplers and fittings
- Consider access requirements and loading points
- Comply with local regulations (UAE, BS EN 12811)
IMPORTANT DISCLAIMER
This calculator provides PRELIMINARY ESTIMATES ONLY and is intended for planning and budgeting purposes. Results should NOT be used for final structural design or construction without verification by a licensed Professional Engineer (PE) or Chartered Engineer (CEng).
By using this tool, you acknowledge that:
1. All calculations are indicative and may not account for site-specific conditions, load combinations, or local code requirements.
About This Calculator
The Scaffolding Calculator helps site engineers and temporary works coordinators estimate scaffold quantities for building facades and access requirements across UAE and Gulf construction projects. Calculate standards, ledgers, transoms, platforms, ties, and bracing for both tube & fitting and system scaffolds with weight summaries for structural verification.
When to Use This Calculator
- Estimating scaffold material for facade works and finishing
- Planning access scaffolding for MEP installation
- Calculating scaffold weights for structural tie-back design
- Preparing scaffold quotations for subcontractor tenders
- Verifying scaffold supplier material schedules
How to Use This Calculator
Enter Building Dimensions
Input the building length, width and height; the scaffold runs round the full perimeter.
Select Scaffold Type
Choose tube & fitting, system scaffold, mobile tower or suspended scaffold; this sets bay length, lift height and tube weight.
Set Load Class and Access
Choose the load class and whether ladder access bays are needed.
Calculate Quantities
Get standards, ledgers, transoms, braces, platforms, toe boards, base plates, an indicative tie count (about 1 per 16 m² of face) and total weight.
Typical Scenarios in UAE & Gulf Projects
A scaffolding contractor budgets a system scaffold round a 40 m × 20 m building, 100 m high (120 m perimeter, 12,000 m² of face). The calculator gives 50 lifts, 98 standards, 4,896 ledgers, 2,448 transoms, 2,400 platforms, about 750 ties at a typical 4 m × 4 m pattern and a total weight of about 113 tonnes. At this height the tie pattern and loads need a scaffold design.
A contractor budgets tube & fitting scaffold round a process building for maintenance. The calculator gives component counts and total weight for transport and crane lift planning; birdcage and special access scaffolds need their own design.
