The method

Longitudinal grade = rise/run × 100; crossfall = transverse rise/width × 100.

Before using the result

  • This is a local worksheet. Findings and supplied criteria remain the responsibility of the person recording them; the output is not a certificate or regulatory approval.
  • Measured geometry only; landings, handrails, surface and other requirements are not assessed.

Worked examples

These original training examples illustrate the method for International Code Council Commercial Building Inspector Examination (ICC B2). Use the matching “Load example” button above to explore a variation; example values are not equipment settings or prescribed criteria.

1. Worked example

Separate longitudinal slope and crossfall in an inspection record. Document the supplied criteria without implying that slope checks cover every accessibility requirement.

Longitudinal rise
0.5 m
Horizontal run
6 m
Crossfall rise magnitude
0.02 m
Horizontal width
1.2 m
Compare supplied criteria
No
  1. Grade = 0.5 / 6 × 100%.
  2. Crossfall = 0.02 / 1.2 × 100%.
  • Longitudinal grade: 8.333333 %
  • Crossfall: 1.666667 %

2. Comparison example

Compare a different supplied condition using the same method. For Inspector Exam, the important check is that the input meaning, units and method assumptions still match the problem.

Longitudinal rise
0.5 m
Horizontal run
8 m
Crossfall rise magnitude
0.02 m
Horizontal width
1.2 m
Compare supplied criteria
No
  1. Grade = 0.5 / 8 × 100%.
  2. Crossfall = 0.02 / 1.2 × 100%.
  • Longitudinal grade: 6.25 %
  • Crossfall: 1.666667 %

Check your understanding

1. Which relationship is used?

Longitudinal grade = rise/run × 100; crossfall = transverse rise/width × 100.

2. Which assumption should you check first?

This is a local worksheet. Findings and supplied criteria remain the responsibility of the person recording them; the output is not a certificate or regulatory approval.

3. How should you verify a different unit system?

Convert every input to the displayed calculation units first. Equivalent physical inputs must give equivalent results; a unit label alone does not convert a number.
