Virtual integrated design and construction

Abstract:"Construction projects involve a large number of both direct stakeholders (clients, professional teams, contractors, etc.) and indirect stakeholders (local authorities, residents, workers, etc.). Current methods of communicating building design information can lead to difficulties including : ? Client di-satisfaction, due to incomplete understanding of the planned construction and the length of the design and construction processes ; ? Functional inefficiencies of the completed facility which could have been designed out had the users been effectively involved in the design ; ? Re-work leading to waste of time and materials due to inaccurate initial work or clashes between components due to conflicting information. Recent surveys [e.g. Egan report, Design and Build Foundation report] show that significant value improvement and cost reduction can be gained by substantially integrated solutions being applied by project teams as a mean of reengineering the project process. In particular, their is considerable benefit to be gained by the integration of design and construction. Objectives The aim of this paper is to present the research carried out in the frame of the CAVALCADE (Collaborative Virtual Construction and Design) project, funded under the European ESPRIT programme HPCN domain. CAVALCADE’s goal was to develop a collaborative virtual prototyping system. Using a distributed architecture, the CAVALCADE system aims to support and enhance concurrent engineering practices therefore allowing teams based in different geographic locations to collaboratively design, test and validate shared virtual prototypes. Several industrial sectors were presented in the CAVALCADE consortium (construction industry, automotive industry, transport industry and aeronautical industry). Representatives of each of these sectors evaluated and reported on the use of CAVALCADE in their business. In this paper, the CAVALCADE system will be presented in details. Technical and organizational difficulties encountered during the project will be presented. Special emphasis will be put on the evaluations done for the participating industrial sectors and these evaluations will be compared to the specificities of the construction sector. As a conclusion, the objectives of new IST project DIVERCITY (Distributed Virtual Workspace for enhancing Communication within the Construction Industry) that will build, among others, on the results of CAVALCADE, will be presented and the modules to be developed (1. Client-briefing workspace, 2. Design review workspace, 3. Construction workspace) will be detailed. 1 CAVALCADE (Esprit project n°26285) started in January 1998. The project is to be finished by December 1999. 2 High Performance Computing and Networking 3 IST project n°13365 . The start date of the project is January 2000."
