| Summary: | 碩士 === 明新科技大學 === 土木工程與環境資源管理系碩士班 === 107 === Circular economies and Building Information Modeling (BIM) have gradually become the trend in the construction industry. However, at the current stage there still is room for improvement in implementation. As these two concepts have no been completely introduced to the construction practice, the users and related authorities are not always familiar with how to apply them.
Take the Holland Pavilion in Taichung as an example case study: it is based on a short construction cycle to build a BIM-based circular economy application model, and by building the necessary data from the circular economy into BIM - and using it through the BIM objective orientation and database-based functionality - synergy is achieved between the two. (Databases include OmniClass, Construction to Operation Building Information Exchange (COBie) and Public Construction Cost Estimate System (PCCES).) The huge database from the backend of the model was extracted to estimate the residual construction value of the Holland Pavilion in Taichung after half a year, and the data was retained in the BIM model through the above coding and the information gathered from the standard construction to construct a BIM-based building materials information model. From this the benefits of BIM in the circular economy could be assessed.
In conclusion, BIM-based circular economy applications models can effectively support users' visual operations, database management, evaluations of the cost of construction and the introduction of coding rules, stringing BIM technology into the whole life-cycle of the projects. This way of storing and exchanging information helps participants to jointly collect all non-geometric attribute data throughout the projects, which helps the management of the circular economy at each stage.
