碩士 === 國立臺灣大學 === 土木工程學系 === 85 === Typically, a building facility is jointly designed by architects and engineerswith different background. After design, construction is also performed by contractors,who may have different experience. These contractors are likely supported by manyother subcontracts. Therefor many parties are involved along the project. As such,created many gaps are among different parties. For example, the gaps between designersand contracts coursed a lot of constructability problems. Poor technical detail andoversights during design phase might result in critical constructability problems,such as schedule delay and resource waste at the construction stage. The interfacebetween the designer and constructor is the critical point to implement a constructionproject successfully and economically. In response to the problems, the objective of this research is to reduce theconflicts between design process and construction operations. The potential problemsamong these two parties were identified by questionnaires and consulted with experiencedengineers. The following list summaries three steps to implement the study. The firstone is clarifying major work items at preliminary design phase and detail phase.Reviewing the characteristics of construction activities is the second step. The lastone is generating various approaches in solving problems identified cause at step 2. Four research results were obtained in this study: (1) identifying key work itemsat design phase; (2) identifying the factors to estimate the duration of design phase;(3) identifying key design work items that will affect construction operations;(4) presenting a design-build model that allows close cooperation between designer and constructor.Keyword : design、constructability、design-build
