Risk-Informed Time-Cost Relationship Models for Sanitation Projects
Publication: Journal of Construction Engineering and Management
Volume 140, Issue 5
Abstract
The purpose of this study is to (1) verify whether the time performance of water and sewer projects is statistically different; and (2) develop time-cost relationship (TCR) models for sanitation projects in Chicago, Illinois. The analysis is performed on data from 180 projects completed in Chicago between 1994 and 2002. Because the time performance of a construction project is not entirely explained by the cost, a practical application is also suggested for using the TCR models confidence level intervals to quantify the qualitative risk level associated with the project time performance.
