A construction project consists of many processes and sub-processes, and it is performed by various participants. In order to successfully complete such complicated construction projects, appropriate performance management is necessary. There have been lots of researches on success factors and performance indicators, but it seems that researches for accurately measuring the performance and success of a construction project are insufficient. Performance indicators have different features to each others in terms of their baselines and units. Therefore, standardization of the indicators are needed to aggregate them into a representative indicator. This paper suggests method of standardization and aggregation of construction project performance indicators using fuzzy inference method. A case study is presented to validate the method.
