Field Install Labor Cost at 72% installation scope captured: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop installation scope captured to 72%, then walk the calculation through step by step. Estimate elevator or escalator field installation labor cost from install hours, loaded field rate, scope capture, and fixed mobilization cost.

The inputs for this scenario

  • Field installation labor hours: 420 crew hr (held at the documented default)
  • Loaded field labor rate: 95 $ / crew hr (held at the documented default)
  • Installation scope captured: 72 % (the input this scenario stresses; the baseline uses 100)
  • Mobilization, supervision, and permit support cost: 3,800 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable field labor cost = field installation labor hours × loaded field labor rate × installation scope captured.
  • Total field installation labor cost works out to 32,528 $ at these inputs, and this is the headline figure for the scenario.
  • Field labor cost per crew hour works out to 77.45 $ / crew hr at these inputs.
  • Variable field labor cost works out to 28,728 $ at these inputs.
  • Mobilization and supervision cost works out to 3,800 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where installation scope captured sits at 100% and the headline result is 43,700 $, this scenario comes in 25.57% below the baseline at 32,528 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to installation scope captured, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a single blended crew rate and does not separately model overtime, prevailing-wage tiers, or productivity loss from stacked trades on a congested site.
