GMP Cleanroom Utilization Cost at 98% suite time assigned to this product or campaign: a worked example

Push suite time assigned to this product or campaign up to 98% and the picture changes. This example computes every intermediate figure at that operating point. a GMP facility team is costing occupied cleanroom time for a patient batch, vector campaign, or production schedule

The inputs for this scenario

  • Occupied GMP cleanroom suite time: 240 suite hr (unchanged)
  • Fully burdened cleanroom cost: 650 $ / suite hr (unchanged)
  • Suite time assigned to this product or campaign: 98 % (raised for this scenario; the documented default is 85)
  • Fixed gowning, clearance, or EM charge: 12,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable cleanroom suite cost = occupied GMP suite time × fully burdened cleanroom cost × assigned share) to the inputs above produces each figure below.
  • At this operating point the engine returns 164,880 $ / period for allocated cleanroom utilization cost, the number this scenario is built around.
  • At this operating point the engine returns 687 $ / suite hr for cleanroom cost per occupied suite hour.
  • At this operating point the engine returns 152,880 $ for variable cleanroom suite cost.
  • At this operating point the engine returns 12,000 $ for fixed cleanroom support charge.

How this compares with the baseline

  • Against the tool's baseline example, where suite time assigned to this product or campaign sits at 85% and the headline result is 144,600 $ / period, this scenario comes in 14.02% above the baseline at 164,880 $ / period.
  • It computes allocated cleanroom cost as occupied suite hours times the burdened hourly rate times the assigned share, plus a fixed gowning, clearance, or EM charge. 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.
