Management Research In The Application Of Cross-sea Bridge Construction Project

Project management in the project activities refers to the specialized knowledge,skills,tools and methods,making project achieve or exceed the needs and expectations of setting process under the condition of limited resources.Project management theory appears after the second world war and forms a discipline theory in the 1960 s.In 1984 for the first time Our country applied project management theory in YunNan Lubuge hydro power projects.With the improvement of the national economy and the development of transportation,the project management practice Significantly enhanced.Sea-crossing bridge had the obvious advantages and developed obviously in the past ten years.DongHai bridge Operated in May 2005 is domestic first cross-sea bridge.Has the characteristics of engineering scale,high cost,bad construction conditions and in order to guarantee the quality and schedule of the cross-sea bridge construction,relative to other conventional Bridges Sea-crossing bridge is put forward the design and construction idea of ‘large-scale,Assembly,factory and standardization',therefore Sea-crossing bridge will be different in the construction method and construction project management convenient.It is very high for sea-crossing bridge construction process to the ship machine equipment requirements and dependence.The quantity and cost of ship investment is very large.Through the bid of a sea-crossing bridge construction business accounting,ship machine equipment investment accounted for more than 55% of the total construction and a conventional bridge construction project is beyond 30%.For data relative lag,the current budget system bid Hong Kong-ZhuHai-Macao bridge is a actual cost accounting into the construction cost of the whole construction period more than 1.5 times of the price of the bid contract.In addition to sea ship installation related components,the prefabricated construction of large components,large prefabricated removed lifting equipment manufacturing,machinery manufacturing,3 d control system to build and temporary waterway dredging take a lot of.Among them,the ship machine equipment costs,excluding fuel expenses,cost more than 30 million yuan per month and a single key engineering ship the monthly rent is 10 million yuan of above.Under the restrictions of limited resources the construction cost structure has somechanges.Sea-crossing bridge construction also caused a certain influence among the three goals of project management: quality target,schedule and cost objectives.From the contract management,material management and equipment management This article in a bid Hong Kong-ZhuHai-Macao bridge as an example descriptive study and experience summary method and excavation is advantageous to the approaches to realize the project goal and means,and summarized and refined,forming system experience.Through literature study,descriptive study and experience summary method it provides the security and has played a positive role for project department organization of choice,and functions of the project department,quality management,material management and risk management and so on.And sums up the sea-crossing bridge bridge construction within a certain time limit,or regular contract period,increasing investment,easy to guarantee the quality of the project target and schedule targets.Through appropriately increase investment,it is easy to improve the efficiency of construction and schedule,and reduce the total cost of construction.
