Composite Layup Labor at 21% handling, kitting and in-process inspection allowance: a worked example

Push handling, kitting and in-process inspection allowance up to 21% and the picture changes. This example computes every intermediate figure at that operating point. planning laminator staffing for a composite layup job

The inputs for this scenario

  • Total ply-area to lay (laminate area × ply count): 420 ply-sq ft (unchanged)
  • Hand layup placement pace per laminator: 55 ply-sq ft / hr (unchanged)
  • Handling, kitting and in-process inspection allowance: 21 % (raised for this scenario; the documented default is 18)

Working through the calculation

  • Applying the documented formula (Base composite layup labor = laminate area multiplied by ply count ÷ layup placement pace) to the inputs above produces each figure below.
  • At this operating point the engine returns 9.24 hr for estimated composite layup labor, the number this scenario is built around.
  • At this operating point the engine returns 7.64 hr for base composite layup labor.
  • At this operating point the engine returns 21 % for layup handling and inspection allowance.
  • At this operating point the engine returns 55 ply-sq ft / hr for layup placement pace.

How this compares with the baseline

  • Against the tool's baseline example, where handling, kitting and in-process inspection allowance sits at 18% and the headline result is 9.01 hr, this scenario comes in 2.54% above the baseline at 9.24 hr.
  • It computes hand layup labor hours by dividing total ply-area by a laminator's placement pace, then adds a percentage allowance for handling and inspection. 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

  • estimated composite layup labor: 9.24 hr (headline result)
  • base composite layup labor: 7.64 hr
  • layup handling and inspection allowance: 21 %
  • layup placement pace: 55 ply-sq ft / hr
