Chaphalkar, N B (2007) Expert system for resolution of delay claims in construction contracts. PhD thesis, Indian Institute of Technology Delhi, India.
Abstract
The construction industry is the second largest industry in the India, being next to agriculture. Construction industry is vulnerable to time and cost overruns which lead to disputes. These disputes if not handled properly tend to drag on and consume time and money of all parties to the contract. The construction projects are of different types and magnitude and most of them are multidisciplinary in nature. With the increasing size and complexity in nature of projects the conditions of the contracts also tend to become more complicated. These complexities give rise to number of claims; which in turn, add to number of disputes to the already existing ones and further delay the settlement of disputes. It was thought appropriate that if a scientific tool was developed for resolution of disputes arising out of one of most dispute-prone clauses, it would serve as a model for further development. Hence this work is an attempt to formulate guidelines to assess the strength of claims arising out of `Time, delay and extension' clause through an expert system called "Construction Delay Claim Advisor". Study of 52 arbitration awards helped in the deeper understanding of the subject as well as grouping the delay claims in six broad areas. Also the factors in the form of probing questions which represent the facts being considered by the arbitrator while giving the award were identified. The database for the system was developed using the published cases settled in the Supreme Court of India and various High Courts of the states. The similarity matching scheme was developed to compare the responses given by the user and the data in the system. Relative importance of the factors in each domain was also determined using a questionnaire survey and fed into the system to get the level of overall matching of the user's case with that of the database cases. The expert system was developed using expert system shell 'iKen Studio' which displays the three matching cases from the database cases with the current case. The system was also validated for its satisfactory performance and stability. Due to non-availability of documented data, the system could not be designed to give the quantum of award. A template is suggested to be included in the award to help the readers including construction professionals and academicians in better understanding of the cases.

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
