| Popis: | 92 The infrastructure is an important subject to evaluate competitive ability for a country. The sewer system is one of the important part of the infrastructure in modern city. However, because many underground utilities do not implement sufficient detail plan and design, making every pipeline unit excavates the road to add or repair pipelines. As a result, causing the inhabitants to live inconveniently, retarding of the transportation, losing of the business and the environmental pollution, etc. Therefore, social cost caused by the important construction must be considered in planning and designing period. This research applying to the storm water sewer construction of Dao-Zhou road at He-Mei Town for case study. This project takes trench method but compared with trenchless methods to understand every cost (including social cost) and beneficial evaluation. The result finds that total cost including quantified social cost and direct cost is NT$44,664,689 in open cut and NT$38,309,779 in trenchless methods. This study results that trenchless method applies even to the countryside the impact of social cost are still lower than the trench method. It is a good reference for choosing the right method when design a pipeline construction project. |
