HVAC Ductwork, Air Handling & Mechanical Products worked example

Labor Utilization at 98% target utilization: a worked example in hvac ductwork, air handling & mechanical products

What does the result look like when target utilization reaches 98%? The full calculation is worked below with real intermediate numbers. Use it to see how much of paid labor time is productive in HVAC Ductwork, Air Handling & Mechanical Products and where the gap to target is.

The inputs for this scenario

  • Productive (direct) labor hours: 320 hr (unchanged)
  • Paid labor hours available: 400 hr (unchanged)
  • Target utilization: 98 % (raised for this scenario; the documented default is 85)

Working through the calculation

  • Applying the documented formula (Labor utilization = productive labor hours ÷ paid labor hours available) to the inputs above produces each figure below.
  • At this operating point the engine returns 80 % for utilization, the number this scenario is built around.
  • At this operating point the engine returns 18 points for gap to target.
  • At this operating point the engine returns 320 value for used amount.
  • At this operating point the engine returns 400 value for available amount.

How this compares with the baseline

  • Against the tool's baseline example, where target utilization sits at 85% and the headline result is 80 %, this scenario lands almost exactly on the baseline at 80 %.
  • A figure at this level is achievable when target utilization is genuinely sustained, not just peaked for a shift. High utilization is not automatically good — it can reflect missing breaks or unrecorded indirect time, and it says nothing about whether the direct hours were spent efficiently rather than on rework or slow methods.

Results at a glance

  • Utilization: 80 % (headline result)
  • Gap to target: 18 points
  • Used amount: 320 value
  • Available amount: 400 value
