Controls Commissioning Time at 40% tuning, integration, and retest allowance: a worked example

Push tuning, integration, and retest allowance up to 40% and the picture changes. This example computes every intermediate figure at that operating point. Use it when controls engineers, BAS contractors, or project managers are planning startup of PLC and BAS logic for heat pumps, tanks, pumps, and heat recovery skids.

The inputs for this scenario

  • Control points and sequences to commission: 220 points (unchanged)
  • Commissioned points per hour: 14 points / hr (unchanged)
  • Tuning, integration, and retest allowance: 40 % (raised for this scenario; the documented default is 35)

Working through the calculation

  • Applying the documented formula (Base controls commissioning time = control points and sequences to commission รท commissioned points per hour) to the inputs above produces each figure below.
  • At this operating point the engine returns 22 hr for required controls commissioning time, the number this scenario is built around.
  • At this operating point the engine returns 15.71 hr for base controls commissioning time.
  • At this operating point the engine returns 40 % for tuning, integration, and retest allowance.
  • At this operating point the engine returns 14 pieces / min for commissioned points per hour.

How this compares with the baseline

  • Against the tool's baseline example, where tuning, integration, and retest allowance sits at 35% and the headline result is 21.21 hr, this scenario comes in 3.7% above the baseline at 22 hr.
  • It converts a count of control points and sequences into commissioning hours, then inflates that base by a tuning, integration, and retest allowance. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required controls commissioning time: 22 hr (headline result)
  • Base controls commissioning time: 15.71 hr
  • Tuning, integration, and retest allowance: 40 %
  • Commissioned points per hour: 14 pieces / min
