Abstract
Research on uncertainty in construction has emphasized the importance of incorporating uncertainty factors in project-cost and time forecasts. However, little attention has been paid to identification and quantification of the specific risks. The present paper focuses on an assessment of the effect of uncertainty on the outcomes of planning. The effect of eight situational variables is evaluated by measuring the schedule and man-hour variances of the project, as well as the extent of usage of plans. The variables examined are number of subcontractors, number of trades, objectives rigidity, percentage completion of design, past construction experience, predictability of weather, availability of labor, and attitudes toward planning. The findings show which of the various situations affect any one planning measure, as well the extent of such influence. The paper concludes with an analysis of the financial implications of the prevailing practice of overlapping design and construction.

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
