Research On WBS Management Of Construction Project Of Shenyang Olympic Center Stadium

The Shenyang Olympic Sports item of basic construction take the items of basic construction, is the Shenyang Municipal government to undertake in 2008 the Olympic Games football competition to plan the construction key sports facilities project. As a whole work, Shenyang Olympic Sports Center which has its own characteristic, from the project proposal written to the project approved, the basic design to detailed, and completing the construction is composed by many small projects. The project scale is huge, the construction time is short, this project's management is very complex, to guarantee the project to complete, various senate construct the unit to unite as one, the absolute sincerity cooperation, the coordinated organization, the master plan, to concert action, the management science in this project implementation are indispensable.With the development of project management, Work Breakdown Structures (WBS) has been introduced into construction project management. In many international developmental items, project managers are required to use WBS to control the project. But for domestic developmental technician items, as few construction projects are required to use WBS, many project managers do not understand the basic concept of WBS and many have no practice to work out the WBS. This article is precisely in view of present this present situation, the union participation Shenyang Olympic Sports Center construction example, to establish the work decomposition structure and has conducted the research in project application this topic. This article first has carried on the elaboration to the work decomposition structural approach's theory and the application. Key elaboration work decomposition aspects and so on structure concept, developing process, formulation principle and decomposition process. Explained: The work decomposition structure demonstrated and had determined must develop or the production product, and was going to complete the working space and the final product related. The success project management is to a great extent depends upon the project superintendent according to the project product and the active characteristic determination project work content and scope ability. But works the decomposition structure to consider that is the present plan and the control project work content and scope most main tools one.The second chapter has carried on the analysis to the environment of the Shenyang Olympic Sports Center construction project, which includes analyses of the feature of the project and the feasibility and inevitability of WBS which was applied in Shenyang Olympic Sports Center construction project. In the environment analysis, as a kind of project management, Shenyang Olympic Sports Center has been divided into many small groups. From the project proposal written to the project approved, the basic design to detailed, and completing the construction, they can be seen as projects at different stages of the life cycle, it is composed by many small projects. It is the feature of itself which decided to apply WBS to carry out the project. Carries out the WBS project management in the Shenyang Olympic Sports Center items of basic construction, is project own characteristic decided: The WBS project management can adapt the environmental variation to suit the items of basic construction uncertainty factor to be many, risk big project. There are many uncertain factors and risks in Shenyang Olympic Sports Center construction project. The construction period is short. Whole works are egg dance; It adapts the items of basic construction scale to be big, integrity strong, multi-department multi-kind of work in a factory combination type processes, combat teamwork's project; It suits the items of basic construction personnel resources inputs to be big, the time requests the tight characteristic; WBS the project management implements strict project manager the responsibility system, and is authorized fully, suits the project construction front long, the scattered work, the fluid big project. All these are in the Shenyang Olympic Sports Center project construction characteristics, therefore, this project especially qualify carries on the project management using WBS. Moreover, WBS adopts"manager responsibility system of a key project under construction"which is suit to dispersive tasks.The third chapter carried on WBS in view of the Shenyang Olympic Sports Center project to manage software package's design, the Shenyang Olympic Sports Center construction project, because the project was huge, the entire project's organizations and agencies are divided into the technical control division, the quality control division, the security control division, the commodity control division, the synthesis department, the human resources department, the production control division and so on seven specialties. According to our country project's concerned requirements and the regular practice, this project decomposition is carries on the decomposition from top to bottom according to the items of basic construction - unit project - individual items - work piece - sub-item project order. Simultaneously has rested on the engineering project construction cycle theory, divides the project construction cycle into the plan, the decision-making, the preparation, the implementation, completion approves five stages. Through to the Olympic Sports Center tennis, the natatorium project carries on the work to decompose, and continues to decompose downward, obtains this project construction progress schedule, the histolysis structure. The activity which after a series of decompositions, grasped the project construction project management plan stage to have probably complete the work which as well as the work contains, and had determined each activity needed the resources, obtained the work decomposition software package finally, in order to each clause one by one explained to the project work decomposition structure.Through the above three chapter of analyses, the fourth chapter proposed applies WBS to this project concrete policing method, mainly includes three parts: Budgetary control, progress control, quality control. Speaking of the entire process's cost control, the establishment science reasonable cost budget is the important forward feed method. Therefore the cost budget must as the basic basis carries on the establishment take WBS. This article completes the resources which through the analysis in the work structure each duty needs, lists resources type which, quantity this project needs to use, then establishment resources plan. According to this is the basis, carries on the item cost the budget, the calculation, the control and the appraisal. In the progress control aspect, carries on the goal decomposition according to various stages control objective according to the specialized kind of work in a factory, according to the overall progress goal, the decomposition progress goal, the formulation specialized sub-package project time node plan, establishes the progress control censorship, carries out the progress control, the inspection adjustment ways and means. Through the supervision sub-package unit strict implement plan, guaranteed that each construction node progress, enables it synchronization to meet the plan time requirements. In the quality control aspect, may defer to the WBS principle design quality control software package, through the quality entire process, the omni-directional control, realizes the engineering project quality to result in the overall control.The paper fifth chapter to managed carries on appraises and asked the existence question as well as the improvement means effectively. Edge detailed is the project characteristic, but this does not mean that does not need to plan. The plan or has not been the optional irresponsible plan project is one kind of project beyond control. The plan formulation needs selects the approach detailed method under the controlled condition limit and the supposition to carry on consummates unceasingly. In the Olympic Sports Center construction process, established the corresponding work decomposition software package using the WBS method to implement the decomposition type management to make the huge progress. Simultaneously should also note, WBS takes an item of comprehensive system's analysis engineering project efficacious device and the project management foundational work, its concept has been familiar with for the project superintendent, content also understand easily, but how will also meet in the actual implementation to apply as well as the question which nimbly will conflict with traditional decomposition method. The results show that WBS plotted the whole project into many small units which are easy to manage, so that project manger is more convenient to estimate the project cost and schedule more accurately. Especially after forming WBS dictionary, it makes the project manager spanned the professional limit to strengthen the relations of technology, materials, equipments and finance field personnel and strong the project management effectively. WBS exerts scientific and effective functions in Shenyang Olympic Sports Center construction project. WBS of construction establishing in this article provides a platform for researching and application of WBS in the future. Project managers can regard this structure as a model, increasing the working efficiency by completing the new WBS through increasing or decreasing new working package.In the synthesis, the project decomposition structure is the project management important method, it passes through in the project management throughout, but the present domestic and foreign project management research area little especially was still the new domain with project procurement management union aspect's research in our country WBS in the large-scale infrastructure aspect's application and the research, the author has conducted some research and the discussion in this aspect. Certainly, this article establishes the work decomposition structure still the need thoroughly supplement and the consummation, hoped that this work decomposition structure can provide certain reference for the project superintendent to use for reference, by in the following research and the application, through carries on to this structure's work increases or the reduction completes the new work decomposition structure the establishment, raises the working efficiency.
