Process Skids, Modular Equipment & Packaged Plants worked example

Commissioning Labor at 92% productive commissioning factor: a worked example

This scenario runs the commissioning labor calculation on the strong side: 92% productive commissioning factor, with every other input held at its documented default. Use it when commissioning labor in process skids, modular equipment and packaged plants is being put through a process skids, modular equipment and packaged plants weighted-cost review.

The inputs for this scenario

  • Commissioning tags checked out: 100 units (unchanged)
  • Commissioning labor rate per tag: 45 $ / unit (unchanged)
  • Productive commissioning factor: 92 % (raised for this scenario; the documented default is 80)
  • Mobilization and standby cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Commissioning Labor cost = quantity × rate × capture factor + fixed cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for weighted cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for per piece value.
  • At this operating point the engine returns 4,140 $ for captured value.
  • At this operating point the engine returns 250 $ for fixed adjustment.

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 14.03% above the baseline at 4,390 $.
  • Use it when budgeting a startup crew or defending a commissioning estimate for a skid or packaged-plant handover. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Weighted cost: 4,390 $ (headline result)
  • Per piece value: 43.9 $ / piece
  • Captured value: 4,140 $
  • Fixed adjustment: 250 $
