Investigations in the BICT project of state-of-the-art ICT for industrialization of house building processes
Abstract: The research presented here is part of a project named BICT, ”Evaluation of benefits of ICT for the indus-trialization of project and product processes in the construction industry”. Its overall objective is to establish a mutual understanding between the construction industry and R&D actors of the needs and possibilities of ICT. The project is a cooperative effort between Swedish and French researchers and industry representatives within the EraBuild program. It includes an investigation of the processes and ICT tools in a representative house building project, together with a study of the State-of-the-Art of ICT for immediate, short and medium term uptake. This paper presents the main results of the State-of-the-Art study with specific focus on: - Visualization and coordination using digital mock-ups of 3D models; - Model based quantity take-off; - Integration of applications for product design; - Reuse of experience based knowledge. The presented study concludes that the use of integrated 3D applications must be introduced early in the project lifecy-cle in order to pave the way for the use of object-oriented information in downstream processes. This requires common standards for 3D based deliveries developed in cooperation between industry and R&D actors through joint analyses of actual information management both in industrialised partnering-like processes, and fully industrial building proc-esses.

Project environment and process design of building projects supported by virtual design and construction methods
Abstract: This paper discusses the project environment and process design of Virtual Design and Construction (VDC) supported building projects. Case studies of the use of VDC methods and tools in construction projects and comparisons made with the evolution of the product development process in the manufacturing industry reveals: (1) Relational contracting in combination with a concurrent engineering process and advanced ICT tools can provide the base for an adaptive Virtual Design and Construction process. (2) There is no single model that contains all project information, but rather a collection of discipline-specific models, including non-model data that can be linked to mod-els. (3) Model information can be exchanged via files or can be available from product model servers. The data format can be proprietary or neutral. (4) An information manager, the Project Information Officer (PIO), is needed who speci-fies the requirements for model use and who ensures integration of models with other models and with non-model data.
