Projectfrom planning, design, contracting and construction is completed, as well as operational management, completed in the limited resources, the completion of the master with the sole and unique and difficult to copy. During the construction of whether such as quality, schedule and budget is completed and whether the original in accordiance with the plan confirmed by the demand to be effective, where the efforts of experts before they may complete. A high-tech plant new construction, from wasteland to the output of the product, a 12-inch wafer fabs from the planning and design, contracting, construction, acceptance to the operation of a reasonable period of time will take about two years. For many years and have enough experience in Taiwan construction time shortened to 12 months, is that synchronous construction will design, bidding and construction of the simultaneous execution, to accelerate the completion of plant construction. High-tech clean room engineering, the face of the compression of time, to be the critical path construction method and strategy, while construction design side to modify the construction, ignored the design and construction process, caused by the unreasonable schedule not well thought out design, test adjustment did not implement the various difficulties in the maintenance of project quality due to scheduling unreasonable, not well thought out design, not implementation of the test to adjust etc, various difficulties in the maintenance of project quality, the engineering quality of the state is often the acceptance of missing can not clean up. The study is for the defect of acceptance, the purpose is to study the types and causes of the acceptance of defect, and futher study prevention measures.
