combined and extended the state-of-the-art research and technologies in the areas of semantic interoperability, virtual organisations and grid technology to provide diverse engineering industries with a platform prototype with flexible, secure, robust, interoperable, pay-perdemand access to information, communication and processing infrastructure. This paper presents some of the key findings and developments related to the semantic grid architecture for virtual organisations and primarily distributed engineering in construction. After a general introduction to the overall vision of the InteliGrid project, the paper presents key identified user roles in the system as well as top end user requirements. This is followed by a description of the system architecture including conceptual, service frameworks and key developed components that the system offers. The paper concludes with a description of an integrated demonstration from the architecture, engineering and construction sector that has been the basis for requirements and validation of the results. Extend the semantic grid paradigm to support dynamic virtual organisations Provide support for shared semantics (semantic interoperability) Demonstrate how typical server side applications can be grid-enabled Demonstrate how client side CAD applications can interface with the grid Include the notion of virtual organisations as an integral part of the IT env. Provide security, authentication, authorisation and access rights support Address firewall configuration issues of secure grid environments Provide transparent grid-based document management operations Provide efficient access to shared heterogeneous data resources Address issues of the virtual organisation dissolution process

Collaborative work environments for CAE/CIC require enabling methods and techniques that can ensure the interoperability of building product models and the data exchange and sharing among a wide range of heterogeneous software tools, taking into account the scattered, multi-discipline nature of construction projects. In this paper we present the concept of an interopera-bility framework which meets such requirements through consistent treatment of: (1) a client-server based operational architecture, (2) a modelling architecture extending the proposed IFC project model of the IAI consortium, and (3) a set of knowledge-based interoperability methods including model mapping, consistency checking and object matching. The reported work is based on research results from the ESPRIT projects COMBI (1993-95) and ToCEE (1996-98).

Whilst knowledge reuse in the lifecycle of projects has been widely studied, most of the known solutions have been focusing on the reuse of communicated information -the process results -isolated from the processes themselves. Consequently, the focus on the immediate reuse of communicated project information (i.e. architectural and structural solutions, drawings, technical specifications and so on) intensified the research in the field of information retrieval and contextualization of the retrieved information. Actual processes, actors and tools that have led to the results of the work usually remain unrecorded, the latter was considered technically almost impossible. In contrast to the intuitive ad-hoc reuse of parts of existing results in a given context, ad-hoc reuse of parts of previously executed processes -together with processes' meta-descriptors -is not so straightforward. In this paper we identify the methods and media in which processes are modeled and executed as a major barrier for process reuse. Based on the analysis of process modeling techniques we suggest a novel methodological approach and a conceptual solution for a collaboration system supported by active process models -utilizing the idea of conceptualized reusable workflow patterns. We present an architecture supporting process reuse, and two early prototypes. At the end, we also outline issues for further research.

This paper presents the Model Access Service (MAS) developed in the EU ISTforCE project (IST-1999-11508). It uses the capabilities of product data technology to provide value added services in a human-centred, web-based collaboration environment. Along with standard services for product model access on model and object level, it encompasses also two advanced knowledge-based features: a Reasoning Agent and an Explanation
