14 In recent years, Building Information Modelling (BIM) has been increasingly employed by the 15 Architecture, Engineering and Construction industry worldwide as a result of digital 16 government initiatives. In spite of some promising early evidence on the benefits of BIM, the 17 momentum of this "top-down" drive should build upon after-implementation empirical 18 evidence. Through the structural equation modeling analysis of survey returns from 145 19 Chinese BIM-enabled projects, this

... ch demonstrates that BIM's degree of 20 implementation can positively affect the acceptability of Integrated Project Delivery (IPD) in 21 the future via increased perception of the need for supply chain incentivization and improved 22 communication quality enabled by BIM. Rolling out BIM on a wider scale may yield an 23 additional benefit in lowering the barrier to the implementation of IPD systems. This finding 24 can serve as evidential support for government mandates that requires the compulsory adoption 25 of BIM in public projects. 26 27 166 such as the accuracy, timeliness, adequacy, and credibility of the information exchanged. In a 167 recent study of trust in Chinese IPD teamwork, Wu (2012) identified communication as one of 168 the major indicators of project performance and measured it using three dimensions, including 169 communication effectiveness, accuracy and degree of involvement. By also reference to 170 Freeman , et al. (2006) and Pocock, et al. (1996) , the current research takes a broader view by 171 defining communication quality as consisting of accuracy, timeliness, transparency, initiative 172 and frequency. 173 Large construction projects mostly span several years in which the interaction 174 between owner and contractor could be intense (Kadefors, 2003). BIM projects are 175 aimed to enhance collaboration by improving information sharing across business 176
