碩士 === 國立交通大學 === 土木工程系所 === 95 === Because of the improving technology and the growing scale of Public Construction, the traditional design/bid/build delivery approach is not sufficient for the current Construction Project. The Turkey project delivery method can supplement this insufficiency. On the basis of the Public Construction commission, in the case of Turkey Project of procurement, there are 9.3 billion NT dollar projects in 2002, 40.7 billion NT dollar projects in 2003, and 55.7 billion NT dollar projects in 2004. Most existing researchs of the Turkey project explore the results and advantages of the Turkey project on the basis of few cases or of homogeneous constructions. Because most of them lack objective evidence and opinions from operational entitles, directors or operational entities don’t have sufficient information to evaluate their projects. Moreover, these researches provoked misunderstanding between operational entities and contractors. Therefore, we collect 1248 Turkey cases from 2002 to 2004 and dissect them. This research is dividend for three topics. First, we discuss/deliberate the point of views from operational entities. Second, we evaluate the results by stastistical analysis — the chi-square test and the Exact Test. The chi-square test is used to examine whether correlation exists between two factors. The categories of factors are identities of procurement, characteristics of contractors, the cost, the schedule and the quality. The exact test is used to analyze the intensity of relationship among three factors and combined with χ2 –test stastistic to explain this relationship. Mostly, exact test is based on the chi-square test and add the third factor which is either the change of budget or the change schedule. Third, we use chi-square test and exact test to evaluate the results from the content of the 2nd topic, questionnaires (random samples from the Public Construction commission) and our additional collections of Turkey projects. However, because of lacking partial information of the 2nd and 3rd topics and the limitation of chi-squrare test, we show the phenomena by using percentage and exact test.
