Knowledge Representation for Constructed Facilities

The current state of information representation in the AEC community leaves much to be desired, yet much can be learned from it. It is important not to lose the accumulated knowledge of many years in the construction industry; however, a new representation is needed, to take advantage of the myriad of computer applications which are being used in the industry today. By examining the semantic net and its application with object oriented techniques, one can see some of the concepts that will no doubt be what carries the industry into a new phase of interoperability. There are a number of current efforts in this direction, and in this thesis, one major effort, the Industry Foundation Classes will be examined. I have also proposed another representation as an alternative, a geometrically based model which will allow use of current object oriented CAD applications to build a representation allowing automation of such tasks as computation of connectivity through the topology of the network. This is a fairly simple example of a representation that could be implemented with the technology available today, allowing organizations in the AEC industry to use information exchange immediately to add value to their software.
