About Project Estimate Builder
Project estimates differ from quotes in commitment level: estimates are approximate (indicative range); quotes are firm prices. A structured estimate breaks scope into Work Breakdown Structure (WBS) components, then applies time or cost per component. Three-point estimating improves accuracy: Expected = (Optimistic + 4 x Most Likely + Pessimistic) / 6 (PERT formula). This accounts for uncertainty better than single-point estimates.
Estimation accuracy by project phase: Concept (-25% to +75%); Feasibility (-15% to +50%); Preliminary design (-10% to +30%); Detailed design (-5% to +15%). Always include contingency (10-20% for well-defined scope, up to 40% for novel work) as a separate line item - never hide contingency in task estimates. Signed client approval of estimates prevents scope creep disputes. Use historical actuals from previous similar projects as the basis for new estimates rather than theoretical calculations alone.
