An Expectation-Behaviour-Reputation Model of Trust-based Relationships in BIM process

The proposed model elucidates that individuals or entities within a Building Information Modelling (BIM) supply chain are required to fulfil the favourable anticipations of individuals or organisations involved in a BIM-centric project. Moreover, they are expected to exhibit appropriate behaviour and conform to the standards expected of a proficient BIM practitioner or organisation. Additionally, they are expected to cultivate a positive reputation by consistently demonstrating positive attributes. Upon conducting a comprehensive analysis of the model, it has been observed that the phenomenon of TBR (temporal behavioural regression) in the BSC (behavioural science context) can exhibit a multitude of manifestations. Interpersonal relationships refer to the dynamic connections that exist between two or more individuals. In various professional relationships within the construction industry, such as between the client and the main contractor, client and sub-contractor, BIM manager and BIM coordinator, BIM manager and project manager, client and BIM consultant, and client and BIM manager, interactions occur. (b) Organisational relationships refer to the connections established between individuals or entities that extend beyond their respective affiliations or employment. Intra-organisational relationships refer to the connections established between multiple individuals within two or more distinct organisations. ? The successful implementation of Building Information Modelling (BIM) in construction projects necessitates the establishment and maintenance of collaborative efforts among the Building Stakeholder Community (BSC) starting from the initial stages of the projects. This collaboration is achieved through the facilitation of information sharing and exchange, knowledge dissemination and transfer, effective communication, and the adoption of collaborative procurement practices. This observation suggests that the Building Information Modelling (BIM) process is characterised by a high degree of cooperation and collaboration. Furthermore, it highlights the significance of trust as a crucial element for fostering and sustaining ongoing collaborative endeavours. Based on these theoretical frameworks, it is possible to discern five fundamental principles that hold substantial importance in comprehending TBR within the context of BSC. ? Trust can be conceptualised as a cognitive process wherein Building Information Modelling Supply Chain Management (BIM-SCM) engages in a deliberative evaluation to determine the level of reliance and confidence in another party. ? Trust can be viewed as a valuable intangible asset that facilitates the exchange of resources within the BIM-SCM. ? Trust plays a pivotal role in fostering effective collaboration within the BIM process, serving as a fundamental component.
