Tank, Vessel & Pressure Equipment Fabrication worked example

Fit-Up Labor at 92% productive fit-up time factor: a worked example

Push productive fit-up time factor up to 92% and the picture changes. This example computes every intermediate figure at that operating point. Use it when fit-up labor in tank, vessel and pressure equipment fabrication is being put through a tank, vessel and pressure equipment fabrication weighted-cost review.

The inputs for this scenario

  • Fit-up joints to complete: 100 units (unchanged)
  • Fully burdened labor rate per joint: 45 $ / unit (unchanged)
  • Productive fit-up time factor: 92 % (raised for this scenario; the documented default is 80)
  • Fixed rigging and tooling charge: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Fit-Up 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 fit-up time factor sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • It multiplies fit-up joint count by a fully burdened per-joint rate, applies a productive-time factor, then adds a fixed rigging and tooling charge for total and per-joint cost. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

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