Skid Assembly Labor at 12% fit-up, staging, and rigging allowance: a worked example

Push fit-up, staging, and rigging allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when planning a skid or module build and you need assembly labor hours you can load against the shift schedule.

The inputs for this scenario

  • Components and connections to assemble: 120 units (unchanged)
  • Crew assembly rate: 12 units / min (unchanged)
  • Fit-up, staging, and rigging allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base skid assembly time = components and connections to assemble รท crew assembly rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required skid assembly labor, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base skid assembly time.
  • At this operating point the engine returns 12 % for fit-up and staging allowance applied.
  • At this operating point the engine returns 12 pieces / min for crew assembly rate.

How this compares with the baseline

  • Against the tool's baseline example, where fit-up, staging, and rigging allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • It computes required crew-hours to assemble a skid from the number of components and connections, the crew's per-minute fit rate, and a fit-up/staging/rigging allowance. 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

  • Required skid assembly labor: 11.2 hr (headline result)
  • Base skid assembly time: 10 hr
  • Fit-up and staging allowance applied: 12 %
  • Crew assembly rate: 12 pieces / min
