Abstract
High-tech industry plays an important role in Taiwan economy. Recently, the out-put value of the three science parks accounts for more than 15% of GDP. The electronic chips made in Taiwan can be found all over the world. However, the high-tech industry has faced with the threat of low profits, due to the global economy crisis and the intensively competitive international business. The only way to survive is the R&D in the science parks. By using the advanced process and technology, more powerful equipment and high quality plant, Taiwan companys will be able to provide higher-profit stocks to the market than foreign completers. In order to achieve this target, not only the high frequency process regeneration and technology improvement are strongly required, but also the more powerful equipment and faster plant renew and construction speed are necessary.
To speed up the construction, high-tech plant construction usually uses fast-track method. The contractors start to construct after the design process starts, and before the process completes. At the same time, sectional construction is also used in the construction process to increase the working faces. When the MEP contractors and civil contractors work at the same time, the project duration is shortened.
On the other hand, due to the fast-track method, the project schedule of high-tech plant construction is rough, lacking details. The net diagram of high-tech plant construction only shows the project milestones which cannot be broken down into activities, causing problems in managing project schedules.
This study emphasizes on how the characteristics of high-tech plant affect the sectional construction and schedule management of high-tech plant construction. Expert interview, literature review and the history case study are used in this study. The line of balance (LOB) method, along with the spatial features of cleanroom sectional construction, and schedule management concept are used afterwards. To replace a rough schedule linked up by milestones, a linear schedule assembled by a series of spatial activities is obtained by this study.
