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.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
