District Energy & Thermal Network Equipment worked example

Field Install Cost at 92% installation scope included: a worked example in district energy & thermal network equipment

This scenario runs the field install cost calculation on the strong side: 92% installation scope included, with every other input held at its documented default. Use it when field install cost in district energy and thermal network equipment is being put through a district energy and thermal network equipment weighted-cost review.

The inputs for this scenario

  • Field-installed length, stations, or packages: 100 ft, m, or packages (unchanged)
  • Installed field cost per unit: 45 $ / unit (unchanged)
  • Installation scope included: 92 % (raised for this scenario; the documented default is 80)
  • Fixed mobilization, shutdown, or permit cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Included variable field installation cost = field-installed length, stations, or packages × installed field cost per unit × installation scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total field installation cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for installed field cost per unit.
  • At this operating point the engine returns 4,140 $ for included variable field installation cost.
  • At this operating point the engine returns 250 $ for fixed mobilization, shutdown, or permit cost.

How this compares with the baseline

  • Against the tool's baseline example, where installation scope included sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • Use it when bidding a buried pre-insulated pipe run, an energy transfer station, or a substation package and you have a unit field rate plus a known lump-sum mobilization. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total field installation cost: 4,390 $ (headline result)
  • Installed field cost per unit: 43.9 $ / piece
  • Included variable field installation cost: 4,140 $
  • Fixed mobilization, shutdown, or permit cost: 250 $
