Abstract:

Using Building Information Modeling (BIM) technology, a unique virtual model of a project can be created, which will allow all parties involved in the design process of project members (owners, architects, engineers, contractors, sub-contractors and suppliers) to collaborate more precisely and more effectively than using traditional processes. The collaboration of the different parties must be linked by a functional system with the presence of software, the team members constantly refine and adjust their portions according to the project specifications and design modifications to guarantee that the model is as precise. Augmented Reality (AR) in turn can bridge the cognitive gap between pre-sale products and real products. Although the presence of Augmented Reality (AR) and Virtual Reality (VR) is necessary, it is necessary to establish a system that directly connects AR, VR, the company, clients, investors and various construction documents. This VR system will be used in the functions of the presale houses between companies, owners and investors. The project that will be used for this study is a building of five floors and two basement located in the District of Zhonghe in Taiwan. As the result showed, for the presentation of the presale house, the technique of the Event-Driven Process Chain (EPC) diagram is used including the import and export of several files. In addition the diagram system gives customers the opportunity to make changes regarding materials, design and time liner in future construction. These different changes made by the customers and approved by the company will generate consequences for the initial contract drawn up by the company. The software Fuzor to ensure the realization of the VR and AR while maintaining a concordance of the different stages of the diagram. To satisfy the requests of the ownership of, the project price and timing, Navisworks and Revit have also allowed the good management of the project. The EPC diagram will have two alternatives, the first alternative will be proposed by the company according to the demand on the market. Then follow the second alternative, this will be the new proposals suggested by the customers after consulting the proposals of the company using VR and AR. At the end of these various changes by the EPC system the prices of materials, other design, the implication Using Building Information Modeling (BIM) technology, a unique virtual model of a project can be created, which will allow all parties involved in the design process of project members (owners, architects, engineers, contractors, sub-contractors and suppliers) to collaborate more precisely and more effectively than using traditional processes.
