Modern Information Techonolgy Based Application Of Qingdao Bay Bridge Constraction Projects Management Information System

Mega bridge projects are very large and complex, which require management and control of content:design, investment, progress, quality, safety, contracts, procurement, payment, information. Therefore, the use of computer-aided management of the means of project management, especially for the duration, quality, schedule management and control, which mandate the completion of the contract the basic requirements and necessary means.Qingdao Bay Bridge building is a high investment and complex process difficult, management coordination is very complicated, difficult construction organization, the reasons include the following. First, for flats and more.. Second, work with many points, front length. Third, synchronization, cross-over work surface. Fourth, short construction period, demanding schedule control. To the Bay Bridge into a high-quality, cost-effective world-class bridge, the need for a scientific and efficient information management system to implement the system on the whole project, a comprehensive, dynamic command and control. To this end, the owner before the construction explicitly put forward the implementation of use of modern project management concepts bridge construction management, to ensure that projects always under control, and in accordance with the established schedule, quality, cost, and security objectives and requirements, the completion of the work.Qingdao Bay Bridge project to improve the management level and efficiency, for the Bay Bridge construction information management needs, this study 4D-CAD technology and project management concepts, introduction to bridge engineering.4D through the establishment of Qingdao Gulf Bridge project information model and the corresponding information integration mechanism to support the 3D modeling system, schedule management system,4D construction management and project management information system data exchange between systems and share information to achieve integration project management. Meanwhile, by introducing the construction schedule and resource allocation optimization theory and simulation technology, Qingdao Gulf Bridge Project construction schedule, resources, cost optimal control, dynamic management and 4D visualization of simulation, in order to improve efficiency and Bay Bridge Construction Information Management provides a new means for the level.The Institute developed the "Bay Bridge construction project management information system" is at home and abroad will be the first 4D-CAD technology in bridge construction project management information system, its research and application results will verify the 4D-CAD technology and project management concept used in the field of bridge engineering theories, methods and techniques, and raise the bridge construction industry, information management, has high practical value and potential applications. The results will also allow construction of the project management from tactical to strategic level has been enhanced, reflecting the system of social and economic benefits.
