Field Install Labor Cost at 110% installation scope captured: a worked example

What does the result look like when installation scope captured reaches 110%? The full calculation is worked below with real intermediate numbers. an installation contractor or estimator needs a field labor cost for a vertical transport project

The inputs for this scenario

  • Field installation labor hours: 420 crew hr (unchanged)
  • Loaded field labor rate: 95 $ / crew hr (unchanged)
  • Installation scope captured: 110 % (raised for this scenario; the documented default is 100)
  • Mobilization, supervision, and permit support cost: 3,800 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable field labor cost = field installation labor hours × loaded field labor rate × installation scope captured) to the inputs above produces each figure below.
  • At this operating point the engine returns 47,690 $ for total field installation labor cost, the number this scenario is built around.
  • At this operating point the engine returns 114 $ / crew hr for field labor cost per crew hour.
  • At this operating point the engine returns 43,890 $ for variable field labor cost.
  • At this operating point the engine returns 3,800 $ for mobilization and supervision cost.

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 9.13% above the baseline at 47,690 $.
  • A figure at this level is achievable when installation scope captured is genuinely sustained, not just peaked for a shift. 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.

Results at a glance

  • Total field installation labor cost: 47,690 $ (headline result)
  • Field labor cost per crew hour: 114 $ / crew hr
  • Variable field labor cost: 43,890 $
  • Mobilization and supervision cost: 3,800 $
