| Summary: | 碩士 === 國立臺北科技大學 === 土木與防災研究所 === 94 === Sewage system is a basic modern public construction. It’s function not only can improve living environment and hygiene, but also can protect river from pollution. At the meanwhile, it is an important facility for water recycling. Modern countries all make sewage system as an important target for environment quality. Nevertheless, sewage system in Taiwan is still far behind. Due to the government invest too less on sewage system. Each year construction expenses not more than 0.1% of GDP. That makes the popularity of sewage system only reach 14%. Ranking of Taiwan is about 46th in the world, showed the fact of our sewage system is far away behind the world.
According to that, these years the government pushes sewage system hard in order to improve citizens’ living quality and national competitiveness. However, the problem of huge construction funds and long-term construct schedule, lead relative bureaus hard to make it. Construction and Planning Agency, Ministry of the Interior bases on past which takes traditional contract suffered plenty of mistakes and low efficiency. Thus, in 3rd term sewage system construction plan cooperate with Law for Promotion of Private Particpation in Infrastructure Projects, uses BOT purchasing model being processed. By the public funds and business efficiency to improves construction quality and operate efficiency, to accelerate sewage system construction. None the less these years the public construction which use BOT model, no matter labors, experiences, techniques, rules and so on. Those are still remain at learning stage, besides the process of signing negotiation acquittal selection of project still exist lots of problem. That’s why sewage system suffering so much challenges, therefore build sewage system becomes harder and harder.
Thus, the study is about to by discussing the problem of the most suitable purchasing model on sewage system to put problems in order. Then discuss the problem of traditional contract and BOT model the problem that sewage system has been suffered. By interviewing experts to make up feasible cases. Through each advantages and disadvantages of feasible cases to analyze and the risky role of each stages of life cycle. Bring the most feasible case “ turnkey amelioration model” and “ payment BTO model” than use Delphi –SWOT analysis to discuss further about feasible interior advantages and disadvantages and the threaten and opportunity of exterior environment which are facing to understand operation goal and accommodative theory. At the same time to cut down subjectively errors. Finally by analyze “ Sewage System Turnkey Construction in Liouying Tainan” to figure out the most feasible purchasing model and expect for relative bureau can be referable.
