What can Quantitative Approaches Do? CPI: Construction Pollution Index Definition: a quantitative measure of pollution and hazards (P&H) generated by a construction project or a specific construction operation during construction. Equation: CPI — CPI of a construction project; CPIi — CPI of a specific construction operation i; hi — P&H magnitude per unit of time generated by operation i; Di — Duration of the construction operation i; n — Number of construction operations that generate P&H.

What can Quantitative Approaches Do? IRP: Incentive Reward Program Definition: a quantitative analysis & control tool for on-site material management, and to motivate workers to reduce material waste. Equation: i — Materials; j — Groups; Q — Quantity of material; P — Price of material; C — Cost of material; n — Number of tasks using material i. Analysis for Construction Environmental Management
