A Multiple Decisive Factor Model for Construction Procurement System Selection
S. Ratnasabapathy and R. Rameezdeen
Department of Building Economics, University of Moratuwa, Moratuwa, Sri Lanka; [e-mail] The procurement system is a key means through which the client creates the pre-conditions for the successful achievement of project specific objectives. Different procurement systems are used for different projects and the appropriate selection may help to avoid problems and be the key to the attainment of project specific goals. In Sri Lanka, the practice of procurement selection is rather unstructured and ad hoc. Therefore a realistic and systematic approach for the selection of the most appropriate system is essential to aid clients in selecting procurement systems. This paper presents a construction procurement selection model based on decisive factors. It particularly examines and analyses factors in terms of clients’ requirements, project characteristics and the external environment in which the construction industry operates. Four rounds of Delphi surveys were carried out to investigate the most important factors and their level of influence on various construction procurement systems. It was found that client requirements are the most
