建築資訊模型(Building Information Modeling, BIM)及4D近年來獲得業界廠商重視與導入，其可應用於工程生命週期的規劃、設計、發包、施工、驗收以及維護等階段，學術研究上亦有諸多案例研究證明期可降低成本、提升施工品質以及增加溝通等效益。 建築資訊模型的應用後，業主、設計單位與施工廠商之責任是否重新配置，建築資訊模型資訊的再使用、再製等所涉之智慧財產權如何保障，依據現有政府採購法、建管規定倘工程專案採用建築資訊模型其契約條款應如何約定、業主如何驗收等問題，皆為推動建築資訊模型之重要課題，本文就上述法律議題進一步探討。

Building Information Modeling (BIM) and 4D modeling have recently attained widespread attention in the architectural, engineering, and construction (AEC) industries. Research efforts demonstrate that the BIM and 4D approaches provide a faster and more effective way of communicating information between interested project parties and a better design which enables improved and innovative solutions as well as many other benefits. Numerous case studies that have also been conducted showed that the use of BIM results in time and cost savings by eliminating unbudgeted changes and unplanned change orders, plus improved cost estimation accuracy and time reduction, clash detections and elimination of rework. With the application of BIM, a number of critical issues arise: the distribution of responsibility and liability among clients, designers, and contractors; the protection of intellectual property rights for the re-use and re-manufacture of BIM information; and the stipulation of issues that need to be addressed in supplements to standard industry contracts that were developed before the existence of BIM technology. This paper aims to give a further exploration and clarification of the legal concerns mentioned above.
