統包採購方式應用於自來水淨水場工程之案例探討

Abstract

由於經濟快速發展對水量需求之驟增，以及水源水質急速惡化影響國民生活品質，因此加速淨水場工程之推動，儼然已成為自來水業界的重要課題。本研究藉由實際案例，探討統包採購應用於淨水場工程之趨勢與其作業情形，並分析其工期成效，以利提供後續淨水場工程採購執行之參考，並提升國內自來水服務品質。 本研究首先就淨水場工程之特性、設計原則及營運操作需求面予以彙整，輔以相關文獻探討統包之理念與定義，進而就其執行法規、制度面進行研究；再以15件實際案例進行比較分析，最後經由專家訪談，整理相關心得與經驗。 本研究主要成果有二點：第一、從早期的傳統採購方式（設計、施工分開），近年來由於統包採購之簡化作業協調、縮短工期、保證運轉功能等效益優點，已成為淨水場工程採購必然選用之趨勢。然為避免因合約執行認知的差距而引起爭議，並確保工程品質，於統包基本設計規範內均依傳統採購的設計標準，將淨水處理程序、設備型式及設計參數等予以嚴格設定，故該「全統包」採購方式已再發展為所謂「半統包」。第二、透過實際案例分析後，4件統包採購(「全統包」加上「半統包」) 淨水場工程的平均工期444天，與2件類似規模之傳統採購工程(平均工期690天)之比較下，採用統包採購約可節省1/3(=(690-444)/690)的興建時程。

Because the economical fast development to increasing suddenly of the water volume demand, And the quality of the water source worsens rapidly affects the national life quality, therefore accelerated impetus of the acceleration water purification field project, has becomes important topic of the running water field. This research use the actual case, to discussion the tendency and its work situation on purchase way of Turn-Key applies in the water purification field project, and analyzes its time result, to provides reference of the following water purification field project purchase execution, and promotes the domestic running water service quality. This research first collects the characteristic, the principle of design and operation demand surface on the water purification field project, auxiliary by the related literatures to discuss its idea and the definition, then research on its execution law, and the system surface; Carries on the comparative analysis again by 15 actual cases, finally by way of the expert interview, reorganizes the related attainment and the experience. This main achievement of the research has two points: First, from the early traditional purchase way (design, construction separates), in recent years ,cause of the benefit on simplification of work and so on reduction time, guarantee revolution function,the purchase way of Turn-Key has becomes the inevitable tendency in water purification field project purchase. However, to avoid the dispute cause by the contract carrying out the cognition disparity, and guarantees the engineering quality, the water purification disposal procedure, the equipment pattern and the design variable has been strictly regulated in the basic design specification depends on the design standard of the traditional purchase.Therefore this purchase way of “the entire Turn-Key” has developed again for so-called “half Turn-Key”. Second, after actual case analysis, 4 cases of purchase on Turn-Key (“the entire Turn-Key” adds on “half Turn-Key”) water purification field project average time 444 days, compared to the traditional purchase project with 2 similar scale (average time 690 days), uses of Turn-Key purchase approximately to be possible to save 1/3(=(690-444)/690) construction time interval.
