小規模基地住宅重建工程預算之探討－以台北市危險老舊建築重建為例

ABSTRACT Title： The Budget of Reconstruction of Small Scale Base Apartment Pages：85 A Case Study of Unsafe Old Buildings in Taipei School：National Taipei University of Business Department：Graduate Institute of Business Administration Time：January, 2022 Degree：Master Researcher：Huang, Ming-chih Advisor：Liu, Han-yu Lai, Ming-cheng Keywords：Dangerous old building rebuilt、 Preliminary construction estimate budget、Estimated construction budget。　　A large number of 4th or 5th floor apartment houses were built in Taiwan in 1960s and 1970s. These buildings are getting older, and furthermore earthquake resistance relative regulations have been modified. According to current earthquake resistance standards, the poor earthquake resistance of these old buildings is not enough and in urgent need of improvement. Taiwan became an aging society in 1993, and it is estimated to become a super-aged society by 2025. In short, this is an age that both population and buildings are facing with aging. However, these old buildings could not ensure structural security and provide barrier-free facilities. 　　The ministry of the interior construction department released "urban danger and rebuilding old buildings ordinance" in May 2017, in order to actively push old buildings reconstruction effectively, a ten-year rebuilding policy. It provides the building volume reward and loosens relevant regulations on construction management, and encourages the public to participate the projects. However the reconstruction of these old buildings is based on the condition that all of land ownership within the scope must agree. In fact, it is not easy to integrate all some reconstruction sites that leads to a small reconstruction site with a volume reward of up to 40%, especially in the high-density urban area of Taipei. It is less economical to reconstruct a small base. However, in fact, more than half of the old and dangerous reconstruction sites in Taipei are smaller than 181 square meters, and the construction cost of small base projects is relatively high. Through this study, it is found that the direct cost of small base projects, such as the width of the front road, the age of adjacent houses, the construction space and other conditions are insufficient, besides the quantity and price relationship, the direct cost may increase by 15-25% 　　This research methods and results hope to provide a way to evaluate the estimated cost of reconstructing unsafe old buildings, and help the rights holders to understand the reconstruction cost. In addition, by using this research method, the calculation of the reconstruction cost can be modified or corrected timely according to the design progress and it helps to control and predict accurately the actual construction cost.
