Municipal Waste Sorting Equipment worked example

Installation Labor at 35% rigging, tie-in, and check-out allowance: a worked example in municipal waste sorting equipment

This scenario runs the installation labor calculation on the strong side: 35% rigging, tie-in, and check-out allowance, with every other input held at its documented default. Use it when scoping an installation outage for a new optical sorter, drum magnet, or screen, and you need a defensible labor estimate for the bid or the shutdown plan.

The inputs for this scenario

  • Install scope items to set: 40 items (unchanged)
  • Items completed per minute by crew: 0.05 items / min (unchanged)
  • Rigging, tie-in, and check-out allowance: 35 % (raised for this scenario; the documented default is 30)

Working through the calculation

  • Applying the documented formula (Base installation labor time = install scope items / crew completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,080 min for required installation labor time, the number this scenario is built around.
  • At this operating point the engine returns 800 min for base installation labor time.
  • At this operating point the engine returns 35 % for rigging and tie-in allowance applied.
  • At this operating point the engine returns 0.05 pieces / min for crew completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where rigging, tie-in, and check-out allowance sits at 30% and the headline result is 1,040 min, this scenario comes in 3.85% above the baseline at 1,080 min.
  • Use it when bidding an equipment install or retrofit, or planning the labor inside a plant shutdown window. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
