Precast Concrete & Modular Construction Manufacturing worked example

Transportation Load Planning at 12% rigging, permit & delay allowance: a worked example

Push rigging, permit & delay allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when transportation load planning in precast concrete and modular construction manufacturing needs a defensible run time before a quote goes out.

The inputs for this scenario

  • Pieces to load and dispatch: 120 units (unchanged)
  • Loading & securement rate: 12 units / min (unchanged)
  • Rigging, permit & delay allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base transportation load planning time = transportation load planning workload รท transportation load planning completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required transportation load planning time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base transportation load planning time.
  • At this operating point the engine returns 12 % for transportation load planning allowance applied.
  • At this operating point the engine returns 12 pieces / min for transportation load planning completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where rigging, permit & delay 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 load-out time by dividing pieces to dispatch by the loading rate to get base time, then multiplying by an allowance factor for rigging, permits and delays. 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.
