Misconceptions About Integrated Project Databases

Abstract: The notion of an integrated project database (IPDB) has existed for decades. Over that time many projects have been undertaken to develop the technologies and frameworks required to implement an IPDB. Also over that time, there has been promotion of the benefits and impacts that IPDB systems will have on the industry. As there are still no industrially stable IPDB systems in existence, the industry's perception of what they are and what they can do has diverged from many of the original presentations. It is also clear that researchers and de-velopers involved in IPDB development have many different ideas about what constitutes an IPDB and what is, or is not, possible to create. This paper aims to describe misconceptions which are growing up around IPDB systems, and presents the authors' view of reality (informed by the opinions of the UK network of experts in ob-jects and integration (URL-1 1999) which was run by the DETR).

Ob ject-oriented caad' - design object structure, and models for buildings, user organisation and site

Abstract: In the early stages of the building design process not only building and site but also user activities and experiences are fonned. In this project conceptual models of some fundamental characteristics of building, site and user organisation will be developed and implemented in a prototype CAD-programme. The programming work for the prototypes is done with Smalltalk on Macintosh computers. The tests of the prototype includes spatial coordination of the three systems. The models are based on an ontological framework which is also used for organising the basic object structure of the prototype CAD program. In the design process, information about the design object is gradually developed. Starthg from certain desired properties, the whole and its parts are fonned by successive increase of detail. The project investigates how the data structure of the design object can be formed to serve this working method. The project also discusses possible future developments. One important question is how these models maybe used in the development of the brief and in the building management stage.
