AP230 is a proposed international standard for the representation and exchange of electronic data relating to structural steel framed buildings. It is still currently under development and not yet accepted as an international standard. Our major objectives in doing this research are to evaluate the AP230 Application Protocol with respect to US practice and extend it for use in early conceputal stges of the facility design process. In this report, we present the problems we identified in AP230 and propose extensions to solve these problems. This report is organized as follows. In the next section, an overview of AP230 is presented. The third section presents the problems we have identified in AP230. The fourth section presents an alternate model to solve the problems. The fifth section presents how this new model can be integrated with AP230. The last section is the summary of this research.
