Abstract
An analysis is described of a sample of pre-bid forecasts for 181 Singapore building contracts awarded between 1980 and 1991 in comparison with previous research results in this topic. Despite the apparent contradictions that occur between findings, it is shown that such differences could be illusionary due to a general lack of reported significance levels together with, in some cases, small sample sizes. As a result it is suggested that a general commonality in outcomes may exist in the form of a single underlying variable.

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
