Phase 1: Project Classification & Estimate Type
Estimate Type Decision Matrix
| Project Stage | Estimate Type | Accuracy | Basis | Use Case |
|---|---|---|---|---|
| Concept | Order of Magnitude | -30% to +50% | SF/unit costs | Go/no-go decisions |
| Schematic | Conceptual/Budget | -15% to +30% | Assembly costs | Budget approval |
| Design Dev | Detailed | -10% to +15% | Quantity takeoff | GMP/bid preparation |
| Construction Docs | Definitive/Bid | -5% to +10% | Full QTO + subs | Lump sum bid |
| Construction | Control | Actual costs | Committed + forecast | Cost management |
