Abstract
Many models have been developed to assist contractors and clients in their cash flow forecasting. The majority of these have been based on standard cash flow S-curves, developed using the traditional manual approach, mathematical and statistical models. Many of these models failed to consider and analyse the factors responsible for the considerable variations in the modelled cash flow profiles. This study as a first step in a knowledge-based expert system (KBES) modelling of construction cash flow to incorporate risk and uncertainties, identified and assessed the risk factors responsible for the variation in construction cash flow profiles. The study was conducted through a questionnaire survey administered on contracting organisations. Analyses were carried out using mean response and univariate analysis of variance (ANOVA). Results showed that the major risk factors involved in cash flow forecasting relate to changes in the design or specifications, contract conditions pertaining to cash in flow, interim valuations and certificates and construction programming issues such as inclement weather. Results also indicated that cash flow forecasting modelling that incorporates risk would need to consider categorisation along the groupings of firm size, procurement methods and construction duration.

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
