Fixture Install Time at 13% shaft access, wiring, and checkout allowance: a worked example

This worked example runs the fixture install time numbers for a tougher week than the baseline: 13% shaft access, wiring, and checkout allowance instead of the typical 18%. Estimate elevator fixture installation time from landing fixtures, install pace, and field allowance.

The inputs for this scenario

  • Car and hall fixtures to install: 44 fixtures (held at the documented default)
  • Fixture mount and terminate pace: 5.5 fixtures / hr (held at the documented default)
  • Shaft access, wiring, and checkout allowance: 13 % (the input this scenario stresses; the baseline uses 18)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base fixture install time = fixtures to install รท fixture installation pace.
  • Estimated fixture installation time works out to 9.04 hr at these inputs, and this is the headline figure for the scenario.
  • Base fixture install time works out to 8 hr at these inputs.
  • Access, wiring, and checkout allowance works out to 13 % at these inputs.
  • Fixture installation pace works out to 5.5 fixtures / hr at these inputs.

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 4.24% below the baseline at 9.04 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. 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.

  • Estimated fixture installation time: 9.04 hr (headline result)
