Distributed Engineering In Construction: Findings from the IMS GLOBEMEN Project

Abstract: Inter-enterprise collaboration to deliver a one-of-a-kind product is gaining momentum with the emergence of new information and communications technologies (ICT) to support information exchange and collaborative work amongst distinct geographically dispersed entities. Typically, the modus operandi of such collaborations is that of the virtual enterprise. While relatively new to some industries, this has been a common mode of operation for the construction industry for long. ICT support for the construction industry to support its ways and modes of operation has however been lacking. While organisation specific proprietary tools do exist, those supporting inter-enterprise collaboration are not up to a similar par. This paper presents the IMS GLOBEMEN (Global Engineering and Manufacturing in Enterprise Networks) and some of its core findings and developments related to reference architecture for virtual enterprises and primarily distributed engineering in construction. After an overall presentation of the GLOBEMEN project, and some basics of inter-enterprise collaboration, the paper presents the main elements of the Virtual Enterprise Reference Architecture and Methodology (VERAM) through identification of its main components and their constituents. This is followed by an exploration of distributed engineering. In this section the focus is on building construction where some very high level use cases are presented. The section is concluded with a presentation of an ICT architecture at both generic and specific levels for distributed engineering at large and product model based distributed engineering in construction in particular respectively.

Keywords: inter-enterprise collaboration, virtual enterprise, distributed engineering, construction.

Architectural computer-aided design systems: an example

Abstract: In 1987, a project was initiated at The IMS Design Research Workshop with the aim to study the effects of the introduction of CAAD methodology on the possible qualitative improvement of architectural design in the Institute's proprietary Building System " GIMS". The system consists of a precast prestressed concrete skeleton structure that incorporates various sub-systems, and has been applied extensively in housing and public building in Yugoslavia and many other countries. Generally speaking, all well-defined and well-structured aspects of architectural design, mainly dealing with the technical aspects and/or graphical presentations, have been successfully modelled and merged with thecomputer application and applied particularly in the detailed design phases. This is not so with the ill-structured problems and fluid situations that dominate the conceptual phase. Many decisions here depend on the subjective judgements of the designer. Knowledge-based systems have been applied in the selected domains to aid decisions based on experience and difficult to model by algorithmic methods. However, how to increase quality of design process is an open-ended question. The semantic aspects of design have not been treated to a great extent in CAAD research projects so far. The paper describes some of the project results - the CAAD methods and tools to be used as aids in conceptual design of the IMS family houses. The tools have been developed to a prototype level, with limited, but adequate testing of their performance.The present versions are applicable on the IBM personal computers.
