What this planner calculates
The tool creates a regular support-position schedule from a route length, preferred spacing and end offsets. It solves the quantity-and-position planning problem without claiming a universal support spacing rule.
Calculation method
The usable interior run is the total length minus the two end offsets. The tool divides that usable run into intervals so that the modeled interval does not exceed the preferred spacing. Support positions are then distributed evenly along the route.
Why spacing is configurable
Actual support spacing can depend on ladder construction, loading, span requirements, structural conditions, environmental factors and the selected manufacturer's system. A fixed generic number would therefore be misleading.
Worked example
A 60-unit route with 0.5-unit end offsets has 59 units of interior planning length. A preferred 2-unit spacing produces a regular support sequence distributed across that run.
Using the result
The output can serve as a preliminary support takeoff and coordination reference. Support positions should then be coordinated with joints, bends, fittings, building structure and access points.
Limitations and safety
This planner does not calculate structural capacity, allowable span, anchor capacity, cable load, seismic requirements or manufacturer-specific support rules. Those checks remain necessary.
Frequently asked questions
Does this determine the required support spacing?
No. Spacing is an explicit user assumption for planning.
Can the first support be at the route start?
Yes. Set the start offset to zero.
Can I use metres or feet?
Yes, as long as every distance input uses the same unit.
