Design management is urban rail transit construction project management of important link, also is the key content of technical management work, through to the design of effective control of the behavior, and provide a reasonable, economical and practical function of the rail transit system in the condition of one.To ensure that rail transit line 6 engineering design to advanced technology, complete functions, the safety of the structure, reasonable economy, combined with engineering construction design management characteristics, as well as the realization design project goals, the design overall and total package management mode(By the owners, the design overall and total package unit, design institute constitute), grading management, and introduced the design consultation management mode. Design overall total package unit organization design institute work orderly, objective and fair to exercise their power of technology, is responsible to the design institute "three control and two management and one harmonize" management work; Responsible for the engineering design of the whole totality, integrity, timely, economic rationality and technical progress, ensure general design rules will run through the whole process of engineering project.In this paper, the research project of GuangZhou metro from the design of the current management mode of practice, with real case as a basis, with strong practical significance. If the project management theory and practice, optimize the design management mode, fully complement each other, apply to new rail transit construction , makes the design and construction of supplement each other, achieve progress, quality, the perfect combination of investment cost. The result of this study related Suggestions and conclusion will be to guide new line design management.This paper first introduces GuangZhou metro line 6 engineering background, design management theory and characteristics. Then, through four design management cases of North/South Metro Line Amsterdam construction project, the RuYiFang station geological disasters processing, DaTanSha main substation design, and electrical system bidding design lag problems analysis, draw relevant experience and lessons, and learn a lesson from that.In GuangZhou metro line 6 engineering design problem analysis, it was found that the design work is currently the difficulties of the features of the project mainly in the complex, remove work difficult, civil construction period risk, construction funds restrict the engineering construction, electrical system period risk, and risk analysis. the design management mode carries on analysis and comparison, focus on the total package design management mode and line 6 of the design overall and total package management mode design analysis and comparison. Use the contrast method, with operated line 2/8 and APM design management mode are analyzed, and their advantages and disadvantages are analyzed.Combining the present line 6 design of existing management are more prominent problems, such as line 6 joint general management way advantages and disadvantages, design personnel flow big effect, project extension of time the influence of the management of design, analysis and pointed to put forward the corresponding improvement ideas. Association suggested to improve the communication mechanism, strengthen the owner to perform supervisory responsibility. Increase the contract terms related constraints, give full play to the design overall and total package management advantage.Therefore, through the above case analysis, problem research, mode contrast, the author puts forward some Suggestions on the construction of the new project design management in further optimize management mode; Ensure that the reasonable design period, put an end to the design cases of the speed up the work schedule, not fully demonstrates, design basic information incomplete; Effective perfect management system, regulating the design work, and perfect the management system; Form community of benefit, achieving the design and construction of the maximum benefit; Further deepening the standard design to shorten the design time, improve the design quality, reduce the cost for the project; To further improve the design contract management.
