This article summarizes the history of the standardization efforts in the architectural, engineering and construction industry and focuses on the three phases of the life cycle of a building, namely design, construction and use phases. Data and information needs of each phase tends to be quite different than one another, thus leading to difficulty in seamless exchange and integration between different constituents of the AEC industry. Downstream data users expect the architect to generate digital design information that is usable in the construction and use phases of a building.s life cycle. Recently American Institute of Architects have assembled a congress in Washington DC, bringing together representatives from the AEC/FM industry, government agencies, software industry and academic institutions. This paper is a summary of the presentation this author gave at this congress in April, 2004.
