Switchgear, Panelboards & Electrical Distribution worked example

Documentation Labor at 58% billable documentation capture rate: a worked example in switchgear, panelboards & electrical distribution

Here is what the math looks like when conditions slip. We hold every other input steady and drop billable documentation capture rate to 58%, then walk the calculation through step by step. Documentation Labor is the engineering and drafting cost baked into every switchgear lineup, panelboard schedule, and electrical distribution submittal package you produce.

The inputs for this scenario

  • Drawings and submittals produced: 100 units (held at the documented default)
  • Drafting labor rate per submittal package: 45 $ / unit (held at the documented default)
  • Billable documentation capture rate: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed submittal setup and archival cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Documentation Labor cost = quantity × rate × capture factor + fixed cost.
  • Weighted cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Per piece value works out to 28.6 $ / piece at these inputs.
  • Captured value works out to 2,610 $ at these inputs.
  • Fixed adjustment works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where billable documentation capture rate sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to billable documentation capture rate, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It models labor as a flat rate per package and does not account for revision cycles that spiral on approval-heavy utility or spec-driven jobs, so pad the capture rate down for customers with many comment rounds.
