網圖模組於大型公共工程主辦機關進度管理之應用

Abstract

工程管理之目標在於完工如期，造價如度，及品質如式。由於營建工程規模日趨龐大，所投入之資金相當可觀，其中尤以大型公共工程建設需配合政府的整體政策，其能否及時完成，往往關乎全民權益與福利，以致工程進度之管理更倍受各主辦機關決策階層所重視。然而大型公共工程主辦機關在工程進度管理上實面臨了許多現存的問題，鑑於這些困難，本研究研擬並建立標準網圖模組資料之基本架構，將網圖模組之觀念應用於工程進度管理的生命週期各階段，除了彙整網圖繪製與審核的知識外，同時亦開發網圖建立輔助系統及網圖審核輔助系統，利用網圖模組標準化的特性導入網圖繪製與審核的自動化，以求達致全面工程進度網圖之模組化及標準化，方便往後的進度管控與資料彙整、儲存之遂行。本研究之實例驗證是以國道新建工程局之工程專案為例，從模組化與標準化網圖的角度，來探討其於工程進度管理的運作模式及效益。

Large-Scale Infrastructure Projects such as expressways often distributed over several regions and need to be broken down into several tendering packages. In order to meet the publicly announced project completion date, a good practice of construction schedule administration is mandatory. To the public agencies that administrate such projects, they will be managing project packages that need to be integrated as a whole. The project packages are very similar in work nature and will be carried out by different contractors with different scheduling practices. Standardization provides a foundation for more efficient and effective schedule integration. However, it is hard to implement considering the number of A/Es and contractors involved. This research proposed a three-stage standardization implementation framework that utilizes the concept of modularization. A set of activity network modules was developed for expressway projects that covered construction of roads, bridges, and tunnels. Two computer systems were also developed to help contractors to use these modules to create the primary part of their schedules, and to help the owner or A/E review contractors’ submitted schedules. The modularization approach with appropriate facilitating software tools also appeared to increase contractors’ level of acceptance to standardization.
