| Abstract |
CAD Layering System is the major technology which effectively controls building information related to the life cycle of a building and its standardization is expected to be the substantial foundation of reinforcing national competitiveness in Architecture, Engineering Construction(AEC) industry through individual capacity and productivity enhancement of their users. In 2004, the Architectural CAD Layer Standards had been established as part of government-led "Construction CALS/EC" project which aimed at the effective management of electronic information in the public construction field. Based on the standards, in 2006, Korean Institute of Architects(KIA) and "major architectural design and engineering firms" had established "CAD Layer Standards version 1.1" as the standards of architectural organizations and agreed to apply the standards to their projects. To clarify the degree of the practical adaptation of the first version of the standards, this study focuses on scrutinizing the actual condition of its application on CAD drawings of the eight major architectural companies which had involved in the establishment of the CAD Layering Standards v.1.1(2006). The collected CAD drawings were created since the agreement until the 31st, December 2008. As a result of the research, only one out of eight companies had tried to apply the standards to their practice. Besides there was no CAD drawing which were completely adapted the standards among the 22 case drawings. Only one drawing appeared to adapt the standards to some extents which means CAD layering system of each company rarely adapted the CAD Layer standards both in qualitative and quantitative terms. Moreover, the questionnaire survey of 627 respondents reveals critical issues regarding CAD layer standardization. In detail, three fourth of all respondents are using layers in their CAD drawings. Only 27.1% of them are aware of the establishment of the CAD Layering Standards v.1.1 though the 94.5% of respondents acknowledge the need for the CAD Layer Standards. The 41.3% of them had been trained to use layers in their practice, however the training time was less than 3 hours in most cases. Also, the 95.1% of respondents believe that they need proper education on CAD Layer Standards. Accordingly, further research is expected to develop the new education methodology of the CAD Layering Standards and thier effective settlement in AEC practice from a national perspective. |
