Refractories, Furnace Linings & Foundry Consumables worked example

Installation Labor at 58% billable time capture factor: a worked example in refractories, furnace linings & foundry consumables

This worked example runs the installation labor numbers for a tougher week than the baseline: 58% billable time capture factor instead of the typical 80%. Installation labor is the crew-time cost of tearing out and rebuilding a refractory lining — bricklayers, gunning operators and helpers billed at a loaded rate.

The inputs for this scenario

  • Refractory installation labor hours: 100 units (held at the documented default)
  • Loaded crew labor rate: 45 $ / unit (held at the documented default)
  • Billable time capture factor: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed mobilization and setup cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Installation Labor cost = quantity × rate × capture factor + fixed cost.
  • Weighted cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Per piece value works out to 28.6 $ / piece at these inputs.
  • Captured value works out to 2,610 $ at these inputs.
  • Fixed adjustment works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where billable time capture factor sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • Use it when bidding or budgeting a lining teardown and rebuild, or when comparing a contractor quote against your own loaded crew rate. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
