Fixture Install Time at 21% shaft access, wiring, and checkout allowance: a worked example

This scenario runs the fixture install time calculation on the strong side: 21% shaft access, wiring, and checkout allowance, with every other input held at its documented default. a field supervisor needs to schedule fixture installation or modernization labor

The inputs for this scenario

  • Car and hall fixtures to install: 44 fixtures (unchanged)
  • Fixture mount and terminate pace: 5.5 fixtures / hr (unchanged)
  • Shaft access, wiring, and checkout allowance: 21 % (raised for this scenario; the documented default is 18)

Working through the calculation

  • Applying the documented formula (Base fixture install time = fixtures to install รท fixture installation pace) to the inputs above produces each figure below.
  • At this operating point the engine returns 9.68 hr for estimated fixture installation time, the number this scenario is built around.
  • At this operating point the engine returns 8 hr for base fixture install time.
  • At this operating point the engine returns 21 % for access, wiring, and checkout allowance.
  • At this operating point the engine returns 5.5 fixtures / hr for fixture installation pace.

How this compares with the baseline

  • Against the tool's baseline example, where shaft access, wiring, and checkout allowance sits at 18% and the headline result is 9.44 hr, this scenario comes in 2.54% above the baseline at 9.68 hr.
  • Use it when planning a fixture rough-in and finish phase, sizing a two- or three-person install crew, or pricing the fixture labor line in a modernization quote. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
