ABSTRACT: Information in construction industry is delivered and interpreted in a language specific to
the industry in which large complex objects are only partially described and with much information
being implicit in the language used. Successful communication therefore relies on participants in the
industry learning how to interpret the language through many years of education, training and
experience. With the introduction of computer technology, and in particular the detailed digital building
information model (DBIM), the accepted language currently in use is no longer a valid method of
describing the building. At all stages in the paper based design and documentation process it is
generally readily apparent which parts of the design require further completion and which are fully
resolved. This is able to be achieved through the complex graphical language currently in use. In the
DBIM, all information appears at the same level of resolution making difficult the interpretation of
implicit information embedded in the model. This compromises the collaborative design environment
which is being described as a fundamental characteristic of the future construction industry.
This paper focuses on two areas. The first analyses design resolution and the role uncertain
information plays in the design process. It then discusses the manner in which designers and the
industry in general deal with incomplete or unresolved information. The second describes a theoretical
model in which a design resolution (DR) environment incorporates the level of design resolution as an
operable element in a collaborative DBIM. The development and implementation of this model will
allow designers to better share, understand and interpret design knowledge from the shared
information during the various stages of digital design and before full resolution is achieved.
