| Abstract | Sharing of product data among discipline specialists and across stages in the product life cycle is difficult in many industries, but particularly so in the highly fragmented architecture-engineering-construction (ABC) industry. The industry currently lacks accepted standards for product data interchange which might allow applications to share the many kinds of graphical and non-graphical data produced and needed in the various stages of the ABC process. As a result, existing practice is to hand-craft interfaces between any given pair of applications at great expense and with chance for re-use. Object-oriented programming in which objects inherit attributes - describing both their state and their behavior - from more general objects in a "frame" or abstraction hierarchy, offers a powerful new approach to sharing information and knowledge in the ABC process. This paper covers the development, present status and future directions for PMAP, an object-oriented building project model developed to facilitate the sharing of information between participants in the design, construction and operation of buildings. We describe a high level user interface developed in AutoCad to capture building component data; we show how this data is then transformed in two steps into an object-oriented building product model; and we demonstrate the feasibility and practicability of using this type of object-oriented product model for information exchange by linking it to two separate knowledge-based systems for generating construction project plans. |
