碩士 === 國立臺灣大學 === 土木工程學研究所 === 95 === In recent years, the case’s quantity and scale of the design-build construction had tendency of the large growth. However, to carryout design-build construction in practical professional management for those items in schedule management, the most concerned reason is the variation of the building administration superintend by the proprietor in the schematic design stage. Even causes the unsatisfied reason that had been requested to finish in a set time and tremendous influence the benefit of design-build construction. That may reduce the time-limited for a project. The self-criticism reason is the investigation time of the government authority (the third party in the contract) that have been neglected and ignored frequently by the proprietor. Because the urban design review is the important item in the administration procedure for the building construction. Although the time influence is the biggest, but the proprietor always requests contractor to finish by a set time, and compress the urban design review schedule in the bidding document. That creates a lot of difference between the actual urban design review schedules. This research scope contains 5 public construction categories; include “the underground parking garage", "the office", "the sport center", "the exhibition hall" and "the housing”. These cases have been approved from the year of 2002 to 2007, January. These research objects are limited in purchase amount over $NT two hundred million, the contract pattern belonging to design-build construction type (the PCM+ site supervision), or the reason of the execution backwardness factor being as the urban design review schedule fallen behind. This research studied by the literature review from, the investigation and the analysis of 15 design-build construction cases in urban design review, the induction influence reason of the design-build construction in urban design review schedule, the synthesis backwardness factor and the countermeasure of the reasonable time in urban design review schedule. That will propose the strategy through the analysis of specialists’ interview, the estimation schedule duration and frequency in urban design review. In order to, get a reasonable urban design review schedule. It will establish the urban design review reasonable schedule of the design-build construction project from the number of times through this research case analysis result. It will provide the proprietor a grading item from the urban design review reasonable schedule, and set a proper contract time-limited section. It will request the contractor to propose a detail analysis about the urban design review reasonable schedule in the tender document. In order to, make the proper action and extra schedule in advance by the special case prejudgment, and also being as the grading item and the control basis.
