摘要

近年來臺灣民眾環保意識日漸抬頭，能有效提升生活品質的污水下水道建設亦同樣受到重視。然而，污水下水道建設費用龐大，對於政府也是一大負擔，有鑑於此，政府大力推動各項民間資源一同參與公共建設。然而以BOT模式興建污水下水道及污水處理設施，同樣產生了許多工程延遲的問題。本研究探討以BOT方式進行污水下水道工程之各項案例中，其各項時程延遲之原因，並試圖找出各主要工程延遲問題之改善策略，以提供未來污水下水道BOT案之參考。
本研究中透過文獻回顧、專家訪談及驗證問卷後，歸納污水下水道工程採用BOT模式之各項工程遲延問題共45項，其中工程延遲影響程度前五高分的原因為：「管線遷移時間過久、」、「管制挖掘(禁挖)」、「不切實際的合約工期」、「變更設計」、「地上及地下障礙物配合拆遷延誤」、「工地現況與原設計不符(如:地質、管線)」六項；發生頻率最高分的五項為：「管線遷移時間過久」、「地上及地下障礙物配合拆遷之延誤」、「變更設計」、「管制挖掘(禁挖)」、「增減工作數量」。而前三項嚴重之工程延遲問題，經專家驗證後：「管線遷移時間過久」可以「政府成立管線協調專責單位」、「政府公權力介入執行」、「變更路徑」為解決策略；「地上及地下障礙物配合拆遷之延誤」則可以「政府公權力介入執行」、「政府成立管線協調專責單位」、「加強政策宣導」為解決策略；「管制挖掘(禁挖)」則可採「分區分段施作」、「管制時間外施作」為解決策略。

In recent years, Taiwan people pay more attention on the importance of environmental protection and aware that the sewer system construction can effectively improve the quality of life. The huge cost of sewer construction is a heavy burden for the government. For this reason, the government promotes private resources joining the public construction in many ways. BOT is one of them. However, the BOT model still cannot avoid the engineering delay in the construction of sewer systems and sewage treatment facilities.
In this study, we try to find out the improved strategies for the construction delay in the cases of sewer system. This could provide reference about sewer BOT project in the future.
Through literature review, expert interviews and validation questionnaire, we summarized 45 delay problems about sewer project adopting the BOT model projects. Those delay reasons in the top five are " pipeline migration time being too long," "controlled excavation (digging forbidden)," "unreasonable contract duration", "" design changes "on the ground and underground obstructions with the demolition delay", "site condition does not match the current situation with the original design (such as geology, pipelines). "Frequency of the five highest score as: "pipeline migration time being too long ", "ground and underground obstructions with the demolition of the delay," "design changes"," controlled excavation (digging forbidden)," "increase or decrease the amounts of jobs."
According to the verification by experts, the top three serious problems of the delay "pipeline migration time being too long" can take the strategy by "Government set up a pipeline coordinator department", "government authority involved in the implementation" and "Change the path". The ground and underground obstructions with the demolition of the delay" can take the strategy by " government authority involved in the implementation ", "government set up a pipeline coordinator department" and "strengthen government policy for the project". The controlled excavation (digging forbidden)" can be solved by "work partition by different areas or durations", "work on outside of the controlled time".
