Applying Time-Chainage Diagram to Mega-Project Construction Scheduling: A Lesson Learned from THSRC

台灣高鐵是一個嶄新而對全台影響甚鉅的重大交通工程，並具有線性排程的工程特性。而要掌握此類重大工程的興建時程，可以藉由幾個常見的排程手法，但是文獻結論顯示，這些早期汎用的規劃手法都有一些缺憾，而想要完好的掌握整體的興建時程，以及能使得規劃的成果在往後的興建過程中能被一貫的使用，這兩個需求必要而急迫，因此藉由比較之後，本研究引進一個新的規劃排程手法：時間－歷程關係圖，來達成這些需求。 本研究之目的在於引進一個新的排程輸出結果，並研究其背景理論及詳細操作步驟，以提供國內外相關大型線性工程專案工程業主，在遭遇相關工程專案時，對於工程之關鍵流程以及時程有整體性的概念及完善的掌握。 因此本研究以台灣高速鐵路工程為範例，經過相關文獻資料蒐集歸納，結合平衡線法與要徑法，建構一個合於規劃相關大型工程的期程模型－LBCPM，並由實際高鐵規劃資料予以實證，以確立能配合規劃結果：時間－歷程關係圖，而能供於世界上大型工程規劃時之使用參考。 本研究可以具體的讓高速鐵路工程的相關大型工程規劃者，藉由研究成果規劃出一個更完善的主計劃時程圖，亦可使各工程業主對高速鐵路興建專案之總體時程特性全盤的瞭解及對規劃時程做有效掌控。Taiwan High Speed Rail Construction (THSRC) is a mega-project of civil engineering which affected whole Taiwan significantly. And the THSCR project has a characteristic of linear scheduling. To control the construction timetable of these major projects, we can approach it by some basic scheduling methods. But from the literature review, these basic methods are not perfect in some aspects. Though these two requirements are indispensible and urgent: to take good control of timetable and to make the conclusion of planning can be employed through all lifetime of construction, we introduced the Time-Chainage Diagram to accomplish these requirements by comparison in this research. The purposes of this research are trying to introduce a new scheduling outcome, develop its background theory and set up the operation steps in detail. In this research, we combined Critical Path Method and Line of Balance to develop a scheduling model – LBCPM in recommendations of literature review. And we certificated the model by real data in planning phase of THSRC. We believe the scheduling outcome：Time-Chainage Diagram can offer a reference in the planning phase to the owners in the world through our model：LBCPM. We believe this research can offer both construction information to the mega-project owner in the world: integral concept of critical path and perfect control of timetable. And though our research, it always a perfect master-plan could be programmed
