Switchgear Build Cost at 92% electrical scope completed in-house: a worked example

What does the result look like when electrical scope completed in-house reaches 92%? The full calculation is worked below with real intermediate numbers. Use it when switchgear build cost in data center and infrastructure equipment manufacturing is being put through a data center and infrastructure equipment manufacturing weighted-cost review.

The inputs for this scenario

  • Switchgear sections or lineups: 100 sections (unchanged)
  • Fabrication and wiring cost per section: 45 $ / section (unchanged)
  • Electrical scope completed in-house: 92 % (raised for this scenario; the documented default is 80)
  • Fixed design and factory test cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Switchgear section build cost = sections or lineups × build cost per section × electrical scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total switchgear build cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for build cost per section.
  • At this operating point the engine returns 4,140 $ for switchgear section build cost.
  • At this operating point the engine returns 250 $ for fixed design and factory test cost.

How this compares with the baseline

  • Against the tool's baseline example, where electrical scope completed in-house sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • A figure at this level is achievable when electrical scope completed in-house is genuinely sustained, not just peaked for a shift. It treats all sections as identical; a lineup mixing main breaker, tie and feeder sections needs separate runs because their wiring effort differs sharply.

Results at a glance

  • Total switchgear build cost: 4,390 $ (headline result)
  • Build cost per section: 43.9 $ / piece
  • Switchgear section build cost: 4,140 $
  • Fixed design and factory test cost: 250 $
