| Summary: | 碩士 === 國立臺灣大學 === 建築與城鄉研究所 === 102 === The un-permitted buildings exist in urban areas in Taiwan almost everywhere. They not only violate building law control regulations, land use control regulations, but also affect the public safety and landscape of cities. By law, un-permitted buildings violating public safety have to be demolished immediately. Otherwise, they can be demolished later. As a result, an objective and reasonable evaluation system for the scheduling of un-permitted buildings is critically needed.
In this study, taking Taichung City as the research target, the status of illegal construction management operations is analyzed. By means of in-depth interviews, various factors for consideration of scheduling are identified and applied to develop an demolition evaluation system for newly added un-permitted buildings. Major research findings are summarized as follows:
1. 8,357 new un-permitted buildings have been reported in the past three years in Taichung. Among which, constructing-buildings were accounted for 15.44% of the total and the removal rate was about 23.90%.
2. According to interviews with experts, among the four evaluation dimensions for demolishing un-permitted buildings, it is found that public safety is widely considered as the most important factor and violation buildings should be demolished on the priority, and then followed by public transportation, cityscape and public health.
3. A set of evaluation factors and operation procedures for demolition scheduling are designed and proposed in this research. Through simulation, they are proved capable for operation.
4. Violators of un-permitted buildings are skeptical in their decision. In order to effectively control the construction of new un-permitted buildings, other penalty programs should be developed to supplement the existing demolition policy. By the collection of penalty fines, hopefully, more adequate funds will be available for the future active management of un-permitted buildings.
