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.
