【正文】 e the client on the demand side. Such configuration puts the architect, engineer and contractor in a very different position that influences not only their roles, but also their responsibilities, tasks and munication with the 5 client, the users, the team and other stakeholders. The transition from traditional to integrated procurement method requires a shift of mindset of the parties on both the demand and supply sides. It is essential for the client and contractor to have a fair and open collaboration in which both can optimally use their petencies. The effectiveness of integrated collaboration is also determined by the client’s capacity and strategy to anize innovative tendering procedures (Sebastian et al., 2021). A new challenge emerges in case of positioning an architect in a partnership with the contractor instead of with the client. In case of the architect enters a partnership with the contractor, an important issues is how to ensure the realisation of the architectural values as well as innovative engineering through an efficient construction process. In another case, the architect can stand at the client’s side in a strategic advisory role instead of being the designer. In this case, the architect’s responsibility is translating client’s requirements and wishes into the architectural values to be included in the design specification, and evaluating the contractor’s proposal against this. In any of this new role, the architect holds the responsibilities as stakeholder interest facilitator, custodian of customer value and custodian of design models. The transition from traditional to integrated procurement method also brings consequences in the payment schemes. In the traditional building process, the honorarium for the architect is usually based on a percentage of the project costs。 1 中文 2878 字 外文 文獻(xiàn) ： The changes of rules brought by BIM Rizal Sebastian TNO Built Environment and Geosciences, Delft, The Netherlands Abstract Purpose – This paper aims to present a general review of the practical implications of building information modelling (BIM) based on literature and case studies. It seeks to address the necessity for applying BIM and reanising the processes and roles in hospital building projects. This type of project is plex due to plicated functional and technical requirements, decision making involving a large number of stakeholders, and longterm development processes. Design/methodology/approach – Through desk research and referring to the ongoing European research project InPro, the framework for integrated collaboration and the use of BIM are analysed. Through several real cases, the changing roles of clients, architects, and contractors through BIM application are investigated. Findings – One of the main findings is the identification of the main factors for a successful collaboration using BIM, which can be recognised as “POWER”: product information sharing (P),anisational roles synergy (O), work processes coordination (W), environment for teamwork (E), and reference data consolidation (R). Furthermore, it is also found that the implementation of BIM in hospital building projects is sti
