摘要: | 當外在社會經濟條件變動,缺工缺料、物價波動,碰上受雨季汛期、工法難易度及專業營造廠商能力等影響,施工難度高的區域排水工程;如何提高廠商投標意願,避免流廢標衝擊區域排水工程發包作業,成為重大關鍵課題。本研究期望協助從業人員於規劃設計階段,即掌握可能造成流廢標因素,加以預防控制,避免發生;又或標案已經流廢標時,得以及時選擇合適因應解決對策。以經濟部水利署暨所屬各河川局及地方政府所轄水利機關所辦理中央管區域排水、縣市管區域排水治理工程範疇,針對主辦機關及承攬廠商實施調查,蒐集意見並檢討工程主辦機關與營造廠商對於不同因素認知差異。採用文獻回顧、專家訪談,歸納造成區域排水工程相關流廢標因素。利用問卷調查進行層級分析法(Analytic Hierarchy Process,AHP)獲取流廢標因素相對重要程度及各因素間之影響性。整體而言,以當市場供應發生狀況時影響最大;個別影響因子,以興建預算編列合理性影響最大,其次為缺工缺料狀況,顯示廠商能否有效管控工程將是關鍵。同時問卷第二部分以序位法調查,對應個別流廢標因素時,解決策略排序以縮短相關單位修正標案時程,加速發包程序;整體而言,當發生流廢標時,工程規模縮減、變更施工難度或是提高預算才有助提升廠商投標意願。;When there exist drastic change of social and economic conditions, such as the lack of workers and materials, and price fluctuations, government agencies overseeing regional drainage projects encounter abandoned bids. The main reasons include the difficulty to construct due to the influence of the rainy season, the limited choice of construction methods, and the inability of professional construction contractors. Thus the key issue is to motivating the willingness of contractors to bid. The outsourcing of drainage works has always been a major issue for the relevant agencies. This research hopes to assist practitioners in the planning and design stage, i.e. to grasp the factors that may cause the abandonment of bids, and to prevent and control them from re-appearing; or when the bids have been abandoned, the agencies can timely choose appropriate countermeasures. Literature review and expert interviews were adopted to summarize the factors that caused the abandoned bids of regional drainage projects. The Analytic Hierarchy Process (AHP) method was applied to obtain the relative importance of the flow rejection factors and the influence of each factor by using the questionnaire survey. On the whole, when the market supply situation occurs, the impact is the greatest; for individual factors, the rationality of the construction budget is given the greatest impact, followed by the lack of labor and materials, indicating that the contractors can effectively control the project is the key. At the same time, the second part of the questionnaire was a sequential investigation. When corresponding to the factors of individual abandoned bids, the solution strategy is primarily sorted to shorten the time for agencies to revise the bids and speed up the re-tendering process. Overall, when the abandoned bids occur, the most helpful approach to improve bidder′s willingness includes reducing the project scale, changing the construction difficulty, or loosening the construction budget. |
