As a newly emerged technology, the BIM technology still possesses many uncertain factors or uncertain trends in the future. Under the background of BIM application in the whole industry, it is generally believed in the whole industry that BIM technology can bring higher economic value, which, however, lacks of strong support of evaluation system. Based on the characteristics of BIM technology, this paper determines the performance evaluation index through integrated methods of questionnaire survey and literature induction, and also establishes a performance evaluation system of engineering projects of BIM technology by using the analytic hierarchy process and fuzzy comprehensive evaluation. The established BIM project performance evaluation system is then applied in a BIM pilot project which has completed acceptance to conclude comprehensive evaluations of the performance of the project.
