Abstract
Risk and uncertainty in construction projects influence the time and cost of construction, the level of project benefits, and the overall economic viability of the project. Risk management could be considerably improved if Client, Contractor, and Consultant had easier and cheaper access to rigorous and credible risk analysis tools. To this end, a construction project risk analysis program for use on a microcomputer is developed. Having thus made this type of program available to a wider body of users, it is then used to validate the concept of risk analysis, to investigate the problem of correlation between risk variables, and to establish the credibility of risk analysis as a management tool. In order to improve the methods of analysing and presenting time and cost risks, a time-risk analysis program is also produced. This is used to examine the duration of the construction phase, and a method for analysing time and cost risk concurrently is developed. The results are presented in terms of 'probability contours' which quantify the probability of achieving values of both the cost and duration of a contract. In addition, since firms are usually involved with more than one project at a time, the concept of corporate risk is investigated; that is, risk arising from a portfolio of projects or contracts.

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
