Abstract
Urban construction, as one of the most important sectors of construction industry in Iran, commonly faces significant cost overruns and delay. The main objective of this study is to evaluate how small, medium and large urban construction projects perform in terms of cost and time. Moreover, different types (road or building) and nature (new or renovation) of construction projects are considered in this research. This study looks at the urban construction projects in Karaj, the capital of Alborz Province, Iran. In this study, 72 urban construction projects are surveyed by reviewing their documents and their real performance. To analyze the collected data, the statistical analyses including class range analysis, independent-sample T-test and correlation analysis are used. This study shows that large urban construction projects are faced higher cost overruns and delay. Moreover, the time- and cost-performance of the new-build projects in overall is better than renovation projects. Furthermore, the cost-performance of urban road projects is better than building projects. The findings offer descriptive statistical cost and time performance information to support realistic time and cost estimation in urban construction projects.

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
