The Research Of The Quality Management In The Expressway Construction Projects Based On Benchmarking

With the increase huge investment put into the public infrastructure Construction field, the expressway have get a rapid development in our country. the expressway's construction quality is pay attention to more and more. The owners as the main construction subject, how to improve the construction quality effectively, how to improve the quality's work performance in the process of construction management,it is a very important problem that need to be solved currently. As an effective management method, Benchmarking is necessary to introduce into the field of construction projects,by combine with the concrete practice, to improve the level of quality management of the expressway construction.In this thesis, the Benchmarking's concrete theory is introduced first, the Benchmarking's advantages and functions are present when it is used in owners quality management, point out the possible obstacles and analyse the countermeasures. In according to its fixed mode of operation procedure, combining with the characteristics of the owners quality Management, Benchmarking can be applied to the expressway quality management. And then, the concrete process and methods, the key factors, the necessary innovation ways are put out when Benchmarking is carried out in the owners qality management.In order to evaluate the performance of the owne s r'quality management effectively, the owners'quality management appraisal Indexes are established, and the appraisal indexes are divided into index of quality assurance, index of quality operation, index of quality operation. comprehensive principal component.the data envelopment analysis(DEA) method is used to evaluate the performance of the owners'quality management. In actual course of operation, the operation are more effective for a single DEA method, and The results can point out the owners'quality management Improvement direction.These research conclusions can be applied to control the construction quality for expressway owner'units, to the expressway construction enterprises and other architecture enterprises,These research conclusions also draw reference value.
