Inspection Checklist Time at 14% documentation, retest, and witness allowance: a worked example

Suppose documentation, retest, and witness allowance falls to 14%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate elevator, escalator, or walkway inspection checklist hours from checklist items, inspection pace, and documentation allowance.

The inputs for this scenario

  • Inspection checklist line items: 185 checks (held at the documented default)
  • Checklist completion pace: 32 checks / hr (held at the documented default)
  • Documentation, retest, and witness allowance: 14 % (the input this scenario stresses; the baseline uses 20)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base checklist time = inspection checklist items รท checklist completion pace.
  • Estimated inspection checklist time works out to 6.59 hr at these inputs, and this is the headline figure for the scenario.
  • Base checklist time works out to 5.78 hr at these inputs.
  • Documentation and retest allowance works out to 14 % at these inputs.
  • Checklist completion pace works out to 32 checks / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where documentation, retest, and witness allowance sits at 20% and the headline result is 6.94 hr, this scenario comes in 5% below the baseline at 6.59 hr.
  • It computes total inspection labor-hours by dividing the checklist line-item count by the completion pace, then adding an allowance for documentation, retests, and witness coordination. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Estimated inspection checklist time: 6.59 hr (headline result)
