Impacts of building information modelling (BIM) on communication network of the construction project: A social capital perspective

Abstract

Building information modelling (BIM) is considered to be significant for organisational communication in construction projects. However, the role of BIM has not been fully shown in practice. To this end, this study examined the impact of BIM on communication network from inter- and intra- organisational relationships in the construction project. First, the structures of the communication networks before and after the use of BIM in a project in China were determined based on the social capital perspective. Then, the social network analysis was adopted to measure the changes in network metrics (i.e., number of ties, density, centrality, centralisation, and clique). Results shows that the connections among nodes are denser, and all the values of the network centralisation decrease after BIM application compared with the situation before BIM use. Nevertheless, results also shows that some construction project participants, who originally have interaction and communication needs, remain unable to establish effective connections among one another even after BIM use. Accordingly, some suggestions were proposed to solve the issues and deficiencies. This research contributes to (a) the state of knowledge by proposing social capital perspective that can identify inter- and intra-organizational relationships of the construction project from social interaction and common cognition to build communication network, and (b) the state of practice by identifying conditions and proposing strategies for strengthening organisational communication and collaboration in BIM-enabled network relationships.

Lean Manufacturing Tools Applied to Human Resource Management and its Impact on Social Sustainability

“…MWG directly and positively affects A3 since β=0.695, explaining up to 48.3 % variance and indicating that using personnel from different departments for problem-solving can lead to efficient and quick solutions. This result agrees with Huang, et al [25], who say that organizations increasingly turn to MWG and A3 in today's business environment to increase efficiency, improve communication and drive innovation.…”

Intelligent Building Construction Cost Prediction Based on BIM and Elman Neural Network

“…The emergence of Building Information Modeling (BIM) technology brings new opportunities to solve the construction cost prediction. As a method based on digital modeling, BIM integrates and manages all kinds of information of construction projects, including data of geometry, materials, time and cost [3][4][5].…”
