A social network perspective of building information modelling in Greek construction projects

ABSTRACT

Building information modelling (BIM) is a technology promoted by governments as a solution to the problems of inefficient communication and limited collaboration in the construction industry. However, there remains a limited understanding of the changes that BIM introduces to the structure of inter-organizational communication and its impact on project participants’ roles and relationships. In this study, these issues are addressed through a comparative study of two construction projects in Greece: one that utilized BIM, and one that did not. Social network analysis (SNA) was employed as an analytical method to examine the inter-organizational communication networks in relation to two types of information exchange – design development and cost management during the design stages of the two projects. Comparative SNA studies were conducted focusing on network density, tie strength, path length, and actor centrality. The research findings revealed the capacity for BIM to improve inter-organizational communication with the BIM-enabled project, exhibiting a higher density of communication, stronger ties, and shorter path lengths between project participants, indicating timely access to higher quality of information. The findings also identified the high centrality of the ‘BIM manager’ and ‘BIM coordinator’, demonstrating the effectiveness of these two new roles in managing the flow of communication in construction teams.
