Abstract: A key point in value engineering (VE) methodology is to acquire and apply knowledge of the assorted fields. An appropriate definition of VE expert knowledge flow could, therefore, yield more productive VE workshops. A conceptual expert case-based reasoning (CBR) framework is introduced in this paper to form a coherent basis for the provision of practically suitable VE expert models. The proposed framework outlines knowledge entities and their relations in the VE workshop. The model benefits from a fuzzy approach to handle uncertainties in the evaluation phase of the methodology. In addition, a computer program is devised, based on the proposed framework, using Borland Delphi 7.0. It comprises an interface representing several phases of the VE job plan. The model is employed in a tunnelling project to demonstrate feasibility of the model in a practical workshop. Owing to its expert nature, the developed model contributes to efficiency of the methodology through providing VE teams with canalized expert knowledge of diverse domains. The propounded model may avail researchers in promoting expert models for pre-construction and specifically VE studies in major construction projects.
