校舍耐震評估、補強執行策略－台南市實例

Key factors of success in seismic evaluation and retrofit lie in competing with earthquakes; however, most of the school buildings were demolished from traditional evaluation system. There is a limitation in the ability to improve the number of buildings in a year under a fixed budget in the government. In order to speed up the pace, Tainan City Government has carried out an overall preliminary evaluation since 2005. According to the results, those with lower seismic coefficient must be further evaluated and academically inspected to examine the evaluation results and retrofit programs. After establishing the inspection mechanism, it was found that there is still a big space for improvement in the traditional evaluation and retrofit approach. Comparing the differences for the last 6 years, it was found that 616 million in NTD was spent from 2003 to 2006 on renovating 14 school buildings. An average of 44 million was spent on each building. After the inspection system came into effect, 256 million was spent from 2007 to 2008 on renovating 25 school buildings, with an average of 10.24 million on each building. On the aspect of time, the first 4 years were spent on renovating 14 buildings, while the latter 2 years were spent on renovating 25 buildings, thereby, increasing the speed of renovating 7 buildings in 2 years to 25 buildings in 2 years. This accelerated the safety improvement of 18 buildings in time. This article explains the strategies of this difference behind the scenes, as well as interprets the experiences of evaluation, inspection and retrofit with the entire case. It also points out suggestions to the Ministry of Education, Construction and Planning Agency, Ministry of the Interior, local governments and technician, based on pace management, financial management, and communication strategies. The success of the project lies in using lesser funds, renovating more buildings with higher safety standards as early as possible.
