碩士 === 國立臺灣科技大學 === 營建工程系 === 106 === In the recent years, Building Information Modeling (BIM) has become a hot topic in Taiwan construction industry. In particular, many large and mid-sized construction companies established BIM teams and invested resource to improve internal BIM ability and enhance competitiveness on the market. However, adopting BIM technology needs to have a high-level skills and integrate with existing working progress. It is a long-term plan that increasing the in-house BIM experience to gain the benefits in return. The purpose of this study is to improve the efficiency of BIM modeling. In order to lead a better modeling efficiency, this research reviewed the time-consuming tasks in the existing BIM framework and provided an improvement plan and verify the results through the method of six sigma. The scope of the research is to focus on building construction from the perspective of contractors. In the existing BIM process, contractors create 3D BIM models based on the 2D CADs provided by design team. In construction stage, contractors usually use BIM models in interface integration and drawing production. The improvement plan will use the Revit API program development (C#) and the visual program – Dynamo to meet the need of automatic production. Following the steps of six sigma, the main work items will be found from 14 completion projects to narrow down the scope of this study. There are two sections to be discussed. The first section is to identify the errors throughout the process of structural modeling and the second section is to revise the models from stakeholders’ comments. After that, the data will be analyzed in sequence through internal brainstorming to reengineer the existing BIM modeling process and verify the solutions. To achieve the goal of this research, program development plays a key role during several times of implementation and adjustment. Finally, throughout being verified by the method of six sigma, the result of this research show a better efficiency in BIM process. Meanwhile, it has become a new framework adopted by BIM team to improve the efficiency.
