Abstract

Construction delays are disruptive and expensive. This study assesses the causes of delays by focusing on actions and inactions of project participants and external factors. The study analyzed quantitative data from completed building projects to assess the extent of delays, and data obtained from a postal questionnaire survey of construction managers to assess the extent to which 44 identified factors contributed to overall delays on a typical project they have been involved with. The findings showed that the factors could be prioritized. However, Pareto analysis revealed that 88% of the factors (representing 39 highest priority factors) were responsible for 90% of the overall delays. This suggests that there is no discernable difference among the different delay factors and none really stands out as contributing to a large percentage of the problem. A one-sample t test further confirmed that most of the factors are important contributors to delays. The results suggest the interdependent nature of construction activities and roles of project participants. The overall ranking of the factors and ranking within each factor category provide useful information for construction industry practitioners, policy makers, and researchers when devising ways of combating delays. The results also indicate areas of construction industry practice that require improvement.

Descriptive scope: 5 PCTEA

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
