In fact, many efforts at international level are in progress to define tools in order to
make easier the multiple exchange of information in different fields of building
design. Concerning this point, protocol and ontology of structured information
interchanges constitute the first steps in this sense, e.g. those under
standardisation by ISO (STEP), PDT models and Esprit project ToCEE.
To model these problems it has brought forth a new research field: the collaborative
design one, an evolution of distributed work and concurrent design.
The CAAD Laboratory of Dipartimento di Architettura and Urbanistica per
l'Ingegneria has carried out a software prototype, KAAD, based on Knowledge
Engineering in the fields of hospital building and of building for aged people.
This software is composed by an Interface, a Knowledge Base, a Database and
The Knowledge Base has been codified by using the formal structure of frames,
and has been implemented by the Lisp language. All the elements of KB are objects
Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components.
Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object).
All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases.
The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.
