營建產業在整個生命週期是由許多專業知識所結合的，當導入資訊技術於其中，但不能依產業整體性之考量抑或完善的跨領域資訊交流機制，將導致工程轉移至下一階段工作單位時，必須重新累積及建立該專案的資訊，使營建專案整體效能無法提高。
機電承包商為了使營建專案整體效能提高，導入3D繪圖軟體建構3D模型，並依照建築3D模型做機電系統配管，但未能完整做干涉檢查，導致承包商於衝突點仍須重新配管，而且所使用的軟體較注重3D模型的呈現，缺乏模型內元件的資訊，使得承包商無法及時得到其元件資訊及數量，還必需額外進行資訊蒐集及數量估算。
而所確立的機電系統進度表如果不能符合機電系統間施工邏輯關係和順序，將導致作業衝突，使的其工程項目必須重做。此外，傳統之物料管理，由於無法延續相關物料之有效資訊，多以執行者的經驗來判斷處理，對於工程進行中日漸龐大之不確定因素已不能有效及時採取因應措施，容易造成停工待料、物料採購不適或物料貨款計價錯誤等困擾。
為解決上述問題，本研究在營建專案規劃設計階段導入建築資訊模型(BIM)，建立「建築BIM機電系統與物料管理整合模式」，主要分為三個部分（一）建築BIM機電系統3D模型建置：建置其核心價值“動態共享機電元件資料庫”，並在建模同時進行各機電系統間的干涉檢查及機電對於結構、建築裝修的干涉檢查，大幅減少之後在施工過程中衝突點的產生，而且在建立機電系統3D模型後，施工圖面及數量表可及時供給整個營建專案所使用；（二）機電系統動態物料需求規劃：建置建築BIM機電系統4D模型，並進行機電系統4D動態工程模擬，其中包含依機電系統施工順序性所建立機電工程進度表結合建築BIM機電系統3D模型，以減少不必要的工項重做。；（三）機電系統物料採購運送時程規劃：利用機電系統動態物料需求資料進行與供應商物料管理的資訊傳遞，以避免停工待料的情形發生。

Construction industry throughout the life cycle is composed of many professional knowledge combined, when you import information technology in them, but not considered by industry or the overall improvement of cross-cutting information exchange mechanism, leading to the transfer to the next stage of work units must be re-accumulation and the establishment of the project information, so that construction can not improve the overall performance of the project.
Mechanical and electrical contractor in order to improve the overall performance of the construction project, construction of 3D graphics software to import 3D models and 3D models made by the building mechanical and electrical system, piping, but do not complete interference check, the contractor at the point of conflict will still result in re-piping, and the more emphasis on using the software rendering 3D models, the lack of information about the model components, allowing the contractor can not receive timely information and the number of its components, must also collect additional information and to estimate the number.
The electromechanical system established schedule if you can not meet the mechanical and electrical systems and the logical relationship between the sequence of construction, will lead to job conflicts, so that its projects must be repeated. In addition, traditional of materials management, inability to extend the effective information-related materials, and more to the experience of the implementation process to determine, for the works in the increasingly large uncertainty has not taken effective and timely response measures, likely to cause downtime to be expected , procurement of materials or materials not paid for pricing errors and other problems.
To address these problems, the study in construction project planning and design stage to import building information model (BIM), the establishment of "electro-mechanical systems and construction materials management BIM integration model", is divided into three parts（一）Construction BIM 3D models built electro-mechanical systems Location: building its core values "dynamic electromechanical components shared database", and simultaneously in the modeling of interference between the electro-mechanical systems and electrical and mechanical inspection for the structure, construction and fitting of the interference check, a significant reduction in the construction process after the conflict points produce, but also in the 3D model was to establish mechanical and electrical systems, construction drawings and timely supply of the number of tables can be used throughout the construction project; （二） Electrical system dynamic material requirements planning: building construction 4D BIM model electro-mechanical systems and electrical and mechanical systems 4D dynamic engineering simulation, which includes electro-mechanical system construction according to the order of the schedule established by the Electrical and Mechanical Construction BIM electromechanical systems with 3D models, to reduce unnecessary redo work items. ; （三） mechanical and electrical systems when transporting materials procurement process planning: the use of the material needs of the dynamic electromechanical system data with suppliers of materials management, information dissemination, in order to avoid downtime to be expected from happening.
