Documentation Hours with documents or data packages of 200 items: a worked example in process skids, modular equipment & packaged plants

This scenario runs the documentation hours calculation on the strong side: documents or data packages of 200 items, with every other input held at its documented default. Use it to budget documentation labor and schedule the crew in Process Skids, Modular Equipment & Packaged Plants.

The inputs for this scenario

  • Documents or data packages: 200 items (raised for this scenario; the documented default is 80)
  • Hours per document: 1.5 hr (unchanged)
  • Documenters assigned: 3 people (unchanged)

Working through the calculation

  • Applying the documented formula (Total labor hours = work items × hours per item) to the inputs above produces each figure below.
  • At this operating point the engine returns 300 hr for total labor hours, the number this scenario is built around.
  • At this operating point the engine returns 100 hr for duration with crew.
  • At this operating point the engine returns 200 items for work items.
  • At this operating point the engine returns 1.5 hr / item for hours per item.

How this compares with the baseline

  • Against the tool's baseline example, where documents or data packages sits at 80 items and the headline result is 120 hr, this scenario comes in 150% above the baseline at 300 hr.
  • Use it at proposal time to price the documentation line, and again at close-out to staff the turnover package against the acceptance deadline. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
