GSE Control Harness Labor Time at 25% routing, test, and rework allowance: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop routing, test, and rework allowance to 25%, then walk the calculation through step by step. Estimate control harness labor hours for airport GSE from harnesses or circuits required, installation pace, and allowance for routing, testing, and rework.

The inputs for this scenario

  • GSE harnesses or circuits required: 180 circuits (held at the documented default)
  • Harness installation pace: 0.42 circuits/min (held at the documented default)
  • Routing, test, and rework allowance: 25 % (the input this scenario stresses; the baseline uses 35)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base harness installation time = harnesses or circuits required รท harness installation pace, converted to hours.
  • Total GSE harness labor time works out to 536 labor hr at these inputs, and this is the headline figure for the scenario.
  • Base harness installation time works out to 429 labor hr at these inputs.
  • Routing, test, and rework allowance works out to 25 % at these inputs.
  • Harness installation pace works out to 0.42 circuits/min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where routing, test, and rework allowance sits at 35% and the headline result is 579 labor hr, this scenario comes in 7.41% below the baseline at 536 labor hr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to routing, test, and rework allowance, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. A single blended pace hides the fact that high-density connectors and shielded circuits run far slower than simple point-to-point runs, so split the job if circuit complexity varies widely.

Results at a glance

  • Total GSE harness labor time: 536 labor hr (headline result)
  • Base harness installation time: 429 labor hr
  • Routing, test, and rework allowance: 25 %
  • Harness installation pace: 0.42 circuits/min
