| Summary: | 碩士 === 國立交通大學 === 工學院工程技術與管理學程 === 107 === The main filed of this research are events of adjacent property damage caused by construction in Zhubei City, Hsinchu County, Hsinchu City and the surrounding area. The real estate markets of these areas are one of the most prosperous in Greater Hsinchu region in recent year. Since the construction activities indeed have huge impact on surrounding environment and buildings, they will lead to inconvenience to the neighborhood residents. If engineering negligence happen, construction and adjacent property damages will occurrence frequently, and they will not only cause both construction companies and residents great loss of life and property, but also consume a lot of society cost.
The main approaches of this research include literature review, expert interview and questionnaire survey, and we analyze further by statistics and comparison to investigate the situation of adjacent property damage in Zhubei area recently. The main study results consist of five points below:
A. Adjacent property damage events happen much more heavily in the areas of urban planning division than the places that outside from them, especially in Hsinchu City and Zhubei City. Hence, adjacent property damageevents take place in the urban areas, where the population density are high, much more easily. Further, Hsinchu City, which is an old urban area, has more chance for adjacent property damageevents happening than Zhubei City, a new urban area, in comparison.
B. The statistical data from questionnaire survey show that the harassments of extortion rings due to adjacent property damage events is the first place in the severity sequence of problem overall.
C. The closer the place to the construction site, the more chance that adjacent property damage events will happen, mostly the adjacent building is away from the construction site in 10 meters. Meantime, the distance more than about triple to the excavation depth, the chance of damaging adjacent housed will be very little.
D. The adjacent property damages happen mostly in basement excavation and process. Notice that there are some chances that adjacent property damages happen when the structure of buildings nearly complete, the reasons may be the materials fall from high altitude, mud of grouting pollute the adjacent house, and the hoisting process affect the adjacent due to the heavy wind of Hsinchu.
E. Less ratio that emergency teams are established when adjacent property damage events happen in-situ, so it is obvious that domestic construction companies pay little attention to disaster management. The crucial point must be improved if domestic construction-related industry wants to enhance the competitiveness.
