Inputs
Enter dimensions in meters. Use local rules for final checks.
Tip: Set equipment width only if carts or machines must pass.
Example data table
| Scenario | Purpose | People | Equipment width (m) | Side allowances (m) | Recommended width (m) |
|---|---|---|---|---|---|
| Electrical rough-in | Work platform | 2 | 0.00 | 0.30 | 1.60 |
| Brick transfer lane | Material handling | 1 | 0.75 | 0.30 | 1.50 |
| Two-way access | Pedestrian access | 1 | 0.00 | 0.30 | 1.20 |
| Small equipment pass | Equipment passage | 1 | 0.90 | 0.30 | 1.80 |

Formula used
All widths are in meters. The calculator selects the governing clear-width check.
1) Worker clear width
WorkerClear = (PeopleAbreast × ClearPerPerson) + ((PeopleAbreast − 1) × GapBetween) + PassingAllowance
2) Equipment clear width
EquipmentClear = EquipmentWidth + (2 × ManeuverClearEachSide)
3) Clear width required
ClearRequired = max(MinClearByPurpose, WorkerClear, EquipmentClear)
4) Recommended total platform width
RecommendedTotal = ClearRequired + (2 × (GuardrailClearEachSide + SafetyMarginEachSide)) + ObstacleAllowance
