Representative change order scenario
Representative case study — not a verified customer outcome.
Change orders are approved on scope alone; schedule disruption, re-mobilization, and margin dilution are not priced in.
Input set
- Original contract value, change order value
- Added days, crew size, daily burn
- Target margin
Hidden loss
Schedule slip and remobilization excluded from change-order price.
Schedule disruption leak
Calculation result
Cost-only change pricing compresses net margin vs target in modeled scenario.
Direct change cost loaded with schedule-disruption and re-mobilization buffers; net margin impact vs target band.
Suggested action
Reprice the change order if net margin falls below the target floor.
Estimated impact: Modeled margin dilution range from delay exposure — illustrative only.
Methodology note
Change-order impact model — illustrative schedule inputs only.
- User-provided schedule and burn rate
- Representative scenario — modeled exposure, not a verified customer outcome.
