1. Introduction to Construction Cost Estimating

1.1 Role and Purpose of Cost Estimating

• Cost estimating as a decision-support tool including (feasibility assessment, budget approval, bid pricing, and cost control baseline)

1.2 AACE Estimate Classification System

• Class 5 — Order of Magnitude: 0–2% design complete, accuracy -50% to +100%, method — capacity factored or parametric

• Class 4 — Conceptual: 1–15% design complete, accuracy -30% to +50%, method — equipment factored or parametric

• Class 3 — Budget Authorization: 10–40% design complete, accuracy -20% to +30%, method — semi-detailed unit cost

• Class 2 — Control: 30–70% design complete, accuracy -15% to +20%, method — detailed unit cost

• Class 1 — Definitive: 50–100% design complete, accuracy -10% to +15%, method — detailed bottom-up quantity takeoff and pricing
