This paper describes a postal survey of UK Quantity Surveyors to relate human factors, such as experience and personality, to early stage estimating expertise. Composite variables were derived by factor analysis and examined against estimates of average national prices for several types of building.
The results indicate a coefficient of variation of 20.5% (17% mean modulus) for the estimates of the 82 respondents. The analysis suggests that expertise does not generalise across generic contract types. It was found that subjects with greater current experience in estimating prices of commercial buildings, who thought training, attribution, length of service, efficiency and discernment to be important, and who are particularly client oriented, tended to overestimate. Subjects with greater current experience in estimating prices of industrial buildings, and who thought cost limits and self-discipline to be important, tended to underestimate.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
