Abstract: Construction consulting companies are among the critical players in ensuring the success of construction projects. This study has attempted to address the issues of Knowledge Management (KM) and IT infrastructure contribution to Project Performance (PP) in construction consulting industry. The link between knowledge management, IT infrastructure and project performance was conceptualized in a way that KM, IT infrastructure contribute to PP. Then, a factor analysis, impact ratio, correlation as well as multiple regressions were used to model the relationship between KM, IT infrastructure and PP. The analytical result shows positive relationship between knowledge management, information technology infrastructure and project performance, through the analysis of regression function, i.e. PP for construction consulting company can be predicted from the implementation of KM and IT Infrastructure. The proposed method provides best model for construction industry to implement effective KM initiatives and information technology infrastructure, to support project performance.
