Commissioning Labor at 58% productive commissioning factor: a worked example

This worked example runs the commissioning labor numbers for a tougher week than the baseline: 58% productive commissioning factor instead of the typical 80%. Commissioning Labor estimates the field cost to check out, loop-test, and functionally verify a process skid or packaged plant — both in total and per tag.

The inputs for this scenario

  • Commissioning tags checked out: 100 units (held at the documented default)
  • Commissioning labor rate per tag: 45 $ / unit (held at the documented default)
  • Productive commissioning factor: 58 % (the input this scenario stresses; the baseline uses 80)
  • Mobilization and standby cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Commissioning 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 productive commissioning factor sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • Use it when budgeting a startup crew or defending a commissioning estimate for a skid or packaged-plant handover. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
