4D Automatic Scheduling in High-Tech Facility Construction

高科技產業在台灣發展迅速，由於高科技產品升級快速及市場競爭激烈，造成高科技廠房的興建必須配合產業追求新技術和快速發展的特性，因此高科技廠房營建專案非常注重「品質」與「時程」的管理。建築資訊模型(Building Information Model, BIM)是一個有效整合各方工程專案資訊的工具，因此若能強化BIM於高科技廠房營建工程中的應用，對於提升高科技廠房建設的「品質」與「時程」有相當大幫助。 目前工程專案實務的時程管理仍難與3D CAD有效結合，多年來，應用4D 視覺化模型的建置流程中，傳統排程的項次與3D模型的項次之整合、CPM時程安排與3D模型建置的平行作業形式，仍有很大的改進空間。如何將3D物件和另一維度(1D Time)之時程安排整合成4D排程，並將之應用於高科技廠房施工的時程規劃管控仍是一大挑戰，仍有待進一步的研究。 因此，本研究的目的主要是在探討：在高科技廠房設施興建的施工排程中，如何以BIM提供的廠房設施資訊模型為基礎，與本研究所提出之動作資料庫與資源資料庫結合，然後透過資料庫之自動運算，得到一個符合專案資源條件之排程建議，作為專案管理人員討論及調整計畫時程的基礎。 本研究最後以臺灣大學電機二館的 7~5 奈米實驗室系統設備安裝工程為例，說明並探討4D自動排程的流程及排程結果，由於本研究之排程結合施工順序 (動作資料庫) 及人力規劃 (資原資料庫)，因此對於施工複雜的高科技廠房及設施工程，能夠提供快速且精確之建議時程做為最後決策參考。High-Tech industry develops rapidly in Taiwan. Due to the highly competitive market and the characteristic of short life-cycles in high-tech semiconductor products, high-tech facility construction must be promoted to adapt the trend. Quality management and schedule management become highly focused in a high-tech facility construction project. Building information modeling (BIM) is a tool that has well performance in integrating construction information. As a result, intensifying BIM applications in high-tech facility must have a great improvement in schedule management in construction site. Schedule and 3D CAD are two critical factors in 4D. However, schedule management and 3D CAD are still hard to integrate in current method. Planning construction schedule and drawing 3D CAD are two separated works. As a result, there is a linking process between 3D CAD and schedule. Integrating 3D model and schedule becomes the critical issue to improve the efficiency of 4D. The goal of this research is to develop a BIM-based automatic scheduling method and apply it on high-tech facility construction. The study first exported the information of high-tech facility objects from 3D model. The 4D automatic scheduling program calculated the duration and arranged the sequence of the objects according to the data in Resource Model and Action Model. Then, the program came up with a project schedule under the resource constraint. Project managers could check the result through the 4D faster than before and formulate the strategy. At last, the study used NTUEE 7-5 Nano Lab as a case study to demonstrate the methodology. This study presents a BIM-based automatic scheduling method that employs 3D objects to generate information required for project scheduling to deal with the complexity of high-tech facility construction and assist construction project managers in making appropriate decisions
