Abstract
Understanding the influences of cost and duration attributes assists developing reliable cost forecasting models and building successful construction projects. This paper presents the findings of a questionnaire survey, which is commissioned to evaluate and rank factors affecting cost and duration of construction projects. A total of 67 effective variables were identified through literature review and interviews, these factors were classified into six different categories. The study is focused on quantity surveyors based in the UK. Statistical analysis is carried out to establish a priority rating of the influencing factors. A detailed discussion of the outcomes indicates a strong agreement between quantity surveyors in ranking the significant variables. The results reveal that the category that contains consultant and design parameters is ranked top followed by client characteristics. Whereas, the third and forth ranks are occupied by project characteristics and external market conditions respectively. On the other hand, the fifth group of factors includes contract procedures and procurement methods, and finally contractor attributes occupy the bottom of the list.

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
