summary The everyday understanding of space may be self-evident and unproblematic. However, as soon as we are asked for a formal definition, e.g. in the context of building classification or product modelling, the concept of space is subject of controversy and misunderstanding. To some, space is the emptiness in which things are embedded, i.e. something immaterial. To others, space has no separate existence but is a property of the material world. Still, according to both views, space can be experienced. In this paper we analyse some influential work within building classification and building product modelling and criticise these for applying a concept of space without factual reference. We explore the ontological foundations for the concept of space, and conclude that space is an aspect view on things; depending on the view, it may be seen both as a property of things and as a thing in itself. Finally we show how construction space can be represented as an object in a conceptual schema for computer based space information.

title Design and Modelling in a Computer Integrated Construction Process - The BAS-CAAD Project

summary A new approach to product modelling in a design context is proposed. CAD-software must not only enable product modelling, but must also support product design. This is not fully achieved in the traditional 'enumerative' approach to product modelling. We discuss how product design and modelling can be based on a facetted' approach to information modelling, and how a data model that supports the design process can be based on a framework for system information. The background for our research is the current development in the construction industry towards a computer integrated construction process. A first prerequisite for this is the use of computer based models. Another prerequisite is that CAD-software can support the design of the results of the construction process, including construction works, user organisations, and the production and facility management processes. A third prerequisite is that computer based models are built with standardised concepts and terminology to enable exchange of information between different actors and computer systems during different stages of the construction process. Principles for organising frameworks for user organisation and construction works information are presented in an appendix.

summary The building industry involves a larger number of disciplines, operators and professionals than other industrial processes. Its peculiarity is that the products (building objects) have a number of parts (building elements) that does not differ much from the number of classes into which building objects can be conceptually subdivided. Another important characteristic is that the building industry produces unique products (de Vries and van Zutphen, 1992). This is not an isolated situation but indeed one that is spreading also in other industrial fields. For example, production niches have proved successful in the automotive and computer industries (Carrara, Fioravanti, & Novembri, 1989). Building design is a complex multi-disciplinary process, which demands a high degree of co-ordination and co-operation among separate teams, each having its own specific knowledge and its own set of specific design tools. Establishing an environment for design tool integration is a prerequisite for network-based distributed work. It was attempted to solve the problem of efficient, user-friendly, and fast information exchange among operators by treating it simply as an exchange of data. But the failure of IGES, CGM, PHIGS confirms that data have different meanings and importance in different contexts. The STandard for Exchange of Product data, ISO 10303 Part 106 BCCM, relating to AEC field (Wix, 1997), seems to be too complex to be applied to professional studios. Moreover its structure is too deep and the conceptual classifications based on it do not allow multi-inheritance (Ekholm, 1996). From now on we shall adopt the BCCM semantic that defines the actor as "a functional participant in building construction"; and we shall define designer as "every member of the class formed by designers" (architects, engineers, town-planners, construction managers, etc.).
