5. 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.

8. 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.
