摘要

It is claimed that the correct choice of a building delivery method will lead to the success of a building project. Hence selecting an appropriate procurement system is an essential step in any construction project process. If a client makes a wrong choice, the penalty may be time and cost overrun and a general dissatisfaction. Despite considerable research into the choice of appropriate procurement systems for construction projects, no generally applicable solutions have been found. This paper reports a research study carried out in Hong Kong on procurement selection. The study aims to develop an expert system to aid the selection of the most appropriate procurement system. A procurement categorization is developed to reflect the current procurement practice in Hong Kong. The model is based on a set of criteria and utility factors derived from ten local experts through 4 rounds of Delphi survey. A statistically significant consensus on the weighting of the utility factors for each procurement system was obtained. The results vividly reveal that Delphi method is a powerful and appropriate technique in deriving objective opinions in a rather subjective area such as the multi-attribute model for the selection of procurement system.
