An integrated decision support system for dealing with time extension entitlements

Abstract

Claims and disputes on time extension for delays are common in construction projects. Various methods and divergent approaches are used by different parties in assessing delays. Disputes then often arise on (a) eligibility of a delay event for claiming extension of time (EOT), (b) choice of method for evaluating EOT, and (c) quantification of the EOT. This research initiative aims at formulating a knowledge-based decision guidance system to help all concerned parties in navigating through these various options, in order to rationalize their approaches towards the preparation and evaluation of the EOT claims. Such rationalization is based on structured approaches, which are in turn devised from the particular contractual and project conditions. This rationalization is also expected to assist in a convergence of assessment approaches that would in turn reduce disputes and consequently wasted resources. In targeting those aims, a prototype of an integrated decision support system (DSS) for dealing with time extension claims was recently developed using (a) a structured web-based decision support framework, which is supplemented by (b) a Pocket PC based portable framework with seamless database integration. This paper presents some essential highlights on the development and usefulness of key modules of the DSS.
