EFFECTS OF BIM IMPLEMENTATION ON NETWORK EMBEDDEDNESS FOR MEGAPROJECT PERFORMANCE IMPROVEMENT

Abstract
Abstract - As large temporary contract organizations, the megaprojects are generally confronted with poor performance issue owing to the complexity and specificity. The effective use of Building information modeling (BIM) has been recognized as one of the critical factors for the success of megaprojects. Particularly, the implementation of BIM provides a digital and synthetic platform to integrate participants during the life cycle of megaprojects. However, limited empirical research has explored the effective pathways for BIM implementation in improving megaproject performance from the perspective of organizational networks. Thus, considering network embeddedness theory, this study intends to determine the relationship between BIM implementation and megaproject performance, as well as considering the mediating effects of networks embeddedness and the moderating effect of relationship norms. The empirical data were collected in China using the questionnaire survey and analyzed by partial least-squares technique for the proposed hypotheses.The results reveal new effective pathways between BIM implementation and megaproject performance through structural embeddedness and relational embeddedness. Meanwhile, relationship norms play positive moderating effect on the relationship between relational embeddedness and megaproject performance. The results deepen the understanding of network embeddedness in BIM-enabled megaprojects, and make up for the lack of research on the megaprojects performance from the perspective of organizational networks. These findings also provide the detailed implementation strategies for BIM and new enlightenment to fully manage network relationships, stimulate the establishment of relationship norms in order to promote megaproject performance.
