「公共污水下水道普及率」為評估國家競爭力之一項指標。截至103年12月全國公共污水下水道用戶接管普及率為37.96%，與先進國家相比仍屬偏低，在政府預算有限情形下，以BOT模式辦理污水下水道已成為趨勢。然國內BOT案在執行過程中糾紛、爭議不斷，例如高鐵、高捷等等。因此，BOT專案之風險管理更顯重要。本研究在藉由實際參與污水下水道BOT專案之專案管理者的經驗回饋，透過專家問卷方式找出專案全生命週期中之風險類別及風險因子，並建立污水下水道BOT專案風險因子之層級架構及相對權重。結果發現，專案全生命週期6項風險類別(5個階段性風險及1個全程性風險)共計24項風險因子中，前5名風險因子之累計權重已達39.24%，前10名之累計權重更是高達62.97%。為達到較佳之風險回應效益，可優先從權重較高之風險因子著手。本研究可供運用於招商徵選階段(即廠商備標階段)之風險評估，及議約簽約階段之風險導向的議約規劃，以及後續執行期間之風險管理規劃、監督及控制等履約管理作為。
Public sewerage coverage was one criterion for evaluating national competitiveness. Under the budget pressure of government, BOT model is becoming a trend to handle sewer. However, domestic BOT case has lots of controversy, therefore, risk management is getting even more important.In this study, we identify risk categories and risk factors of the project full life cy-cle through questionnaire to the expert who had sewerage BOT project experience. And then we established risk factors sewerage BOT project of the hierarchical structure and relative weights.The findings shows that there were 24 risk factors in the six risk categories, in-cluding five stages of risk and a full risk. The cumulative relative weight of top five factors is 39.24% and top ten factors is 62.97%. For promoting benefit, we can plan re-sponse strategy for the high weight of the risk factors.This research can be applied for project risk assessment in merchants levy election stage, risk-based planning in negotiation of contract stage, risk management planning, monitoring and control and performance management in the other project stages.
