| Abstract |
Since building design outcomes become bigger and more complex and are based on inter-dependence of numerous specialized participants, design cooperation has been considered more important in the design process. In small-scale public building projects, there is no established procedures and guidelines for building design cooperation in contrast to large public building projects. For this reason, communication and cooperation between participants for the design are difficult, furthermore the quality of the final design results is deteriorated. In this study, the 231 cases of design changes for 8 small-scale projects have been analyzed in terms of design phases and participants, and the critical management items of the design cooperation have been induced. A design cooperation process model is presented for small-scale public building projects, which includes a decision-making step in the design development phase. From the interviews of 14 design practitioners, we conclude that the model can contribute to the reduction of design changes and the improvement of design quality. |
