VIPP: Visualization in Design and Construction
2007 (English)Report (Other academic)
The purpose of the VIPP project is to improve the efficiency and quality of the design review and production scheduling process by using VR models based on 3D models from the design process. Visualization is increasingly used in early stages of development projects to facilitate communication processes, but the use of these models during phases such as detailed design, planning and construction is very limited. It is time-consuming and complicated to keep a VR model up-to-date as a result of differences in data structures and formats between the 3D CAD applications and VR applications. The VIPP project aims to facilitate the transfer of 3D CAD models to VR applications, but the main objective is to set a true example for the practical use of 3D models by professionals in the construction industry. The VIPP project shows in a real construction project that VR models are beneficial for design review and construction scheduling purposes. By means of defining scenarios for the early and detailed design review process and for production scheduling purposes the project shows benefits that can be divided in: facilitation of the communication process with project stakeholders, increased process efficiency and higher quality of the design and construction process outcome. The VIPP project shows that the 3D design process is different from the traditional 2D design process, but not radically different. The time required to create 3D and 4D models for the industry case study project was surprisingly little. However, it was found that it is critical to define early and clearly in a project for what purposes the 3D models will be produced. IFC, a neutral exchange format for building model information, is used to capture and transfer graphical and non-graphical data from 3D CAD models to VR applications. An IFC interface was developed for two VR applications in the VIPP project, but is set up in such a way that other VR applications also can benefit from the developed IFC interface. The objective of the VIPP project was to keep the definition of use cases, requirements and processes concrete in order to maximize the practical applicability of the VIPP project for other professional users in the construction industry. The practical approach might have compromised the scientific level of the project work, but we believe that the concrete results from the VIPP project can stimulate the industry to start using 3D models and VR environments in real building projects.
