Energy Transfer Skid Assembly Labor at 7.2% fit-up, test, and documentation allowance: a worked example

This worked example runs the energy transfer skid assembly labor numbers for a tougher week than the baseline: 7.2% fit-up, test, and documentation allowance instead of the typical 10%. Estimate shop labor hours to assemble district energy transfer skids, pump modules, heat exchanger packages, and prefabricated valve/meter assemblies.

The inputs for this scenario

  • Skid assembly work packages: 120 packages (held at the documented default)
  • Assembly completion pace: 12 packages / hr (held at the documented default)
  • Fit-up, test, and documentation allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base skid assembly hours = skid assembly work packages รท assembly completion pace.
  • Required skid assembly labor hours works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base skid assembly hours works out to 10 hr at these inputs.
  • Fit-up, test, and documentation allowance works out to 7.2 % at these inputs.
  • Assembly completion pace works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where fit-up, test, and documentation allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • Use it when planning shop labor for prefabricated energy transfer skids and you need committed hours that include testing and documentation overhead. 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.

Results at a glance

  • Required skid assembly labor hours: 10.72 hr (headline result)
  • Base skid assembly hours: 10 hr
  • Fit-up, test, and documentation allowance: 7.2 %
  • Assembly completion pace: 12 pieces / min
