Towards a case-based reasoning framework for construction projectplanning and control

Abstract: The work presented in this paper is aimed at investigating the extent to which both 'user andsystem decision-making' in construction project planning and control can be captured andstored for future use. This paper presents work being conducted to establish a frameworkfor the application of CBR to construction planning and control. Due to the highvariability in the type, size, and complexity of construction projects the work concentrateson the use of the technique for information re-use in project planning and control forhighway bridge construction. Object models for a bridge and its components have beendeveloped, and used to develop a prototype application, CBRidge. The application takesbridge information from databases and adds it to cases bases which can then be used forcase matching. Once a suitable case has been found it can be adapted to more closelymatch the new project, and following this the adapted case can be linked to a planningmodel, enabling the plan for the matched case to be adapted for use with the currentproject. It concludes by discussing the benefits of the approach and the limitations of thesystem, together with future directions.

Keywords: construction planning, bridges, object modelling, databases, case-basedreasoning.
