Abstract
This paper presents a structured, two-pronged approach to the development of a framework for assessing the severity of occurrence of design revisions and determining the causes of these revisions. The development of the framework involves the identification of a causal taxonomy consisting of categories of the causes of design revisions and the formalization of a set of indices for measuring and comparing the magnitudes of designer-times expended on design revisions. The framework could be used both as a diagnostic instrument to determine the health of the design phase and also as a forecasting tool for the estimation of designer resources required for a construction project. The framework was tested using data obtained from twelve building projects in China. The category that caused the maximum expenditure of designer time on design revisions in the building projects surveyed was found to be owner-initiated changes.

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
