Waste-to-Energy Equipment worked example

Field Commissioning Cost at 54% onsite productive-time fraction: a worked example in waste-to-energy equipment

This worked example runs the field commissioning cost numbers for a tougher week than the baseline: 54% onsite productive-time fraction instead of the typical 75%. Estimates field commissioning cost for waste-to-energy equipment from crew hours, billing rate, and the share of onsite time that is genuinely productive.

The inputs for this scenario

  • Total field commissioning labor hours: 640 hr (held at the documented default)
  • Commissioning crew billing rate: 145 $/hr (held at the documented default)
  • Onsite productive-time fraction: 54 % (the input this scenario stresses; the baseline uses 75)
  • Travel, lodging & per diem: 28,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Cost = labor hours x billing rate x productive-time % + travel & per diem.
  • Total field commissioning cost works out to 78,112 $ at these inputs, and this is the headline figure for the scenario.
  • Field commissioning cost per unit works out to 122 $ / piece at these inputs.
  • Variable field commissioning cost works out to 50,112 $ at these inputs.
  • Fixed field commissioning cost adder works out to 28,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where onsite productive-time fraction sits at 75% and the headline result is 97,600 $, this scenario comes in 19.97% below the baseline at 78,112 $.
  • Use it to price a commissioning scope, compare in-house versus OEM crews, or budget a startup mobilization for a new or retrofitted WtE line. 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.

Results at a glance

  • Total field commissioning cost: 78,112 $ (headline result)
  • Field commissioning cost per unit: 122 $ / piece
  • Variable field commissioning cost: 50,112 $
  • Fixed field commissioning cost adder: 28,000 $
