Evans, R C and Kaka, A P (1998) Analysis of the accuracy of standard/average value curves using food retail building projects as case studies. Engineering, Construction and Architectural Management, 5(1), pp. 58-67. ISSN 0969-9988
Abstract
Several cash flow forecasting models have been developed for use by the contractor at the tendering stage. The majority of these models have been based on the standard S-curve. The accuracy of these models depends on the accuracy of the standard S-curve used. Many researchers have attempted to develop standard S-curves using past projects. These projects were primarily classified in terms of broad-based categories (e.g. commercial buildings). The results of past research have demonstrated that cumulative value/cost curves vary significantly. In the present paper, a more specific type of building was selected (food retail stores). Historical data for 20 projects was collected and analysed for the feasibility of developing a more accurate standard S-curve. The results demonstrate that an accurate standard S-curve was not achieved even when projects were further classified into more detailed groups (i.e. different sizes of superstores).

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
