Study On Progress Control And Coordination Of Multi-items Parallel Construction

With the rapid development of our country's economy, large projects have mushroomed of springing. However, organization and coordination, progress management of large project construction is still in the stage of exploration. Therefore, the research on process management theory and schedule control technology of large project implementation stage is necessary.The paper's research background is Tang Daming place national heritage park construction project. The construction project is complex, with more cross work face and strong unpredictable nature, as well as many cooperative building units. Concurrent engineering is used in the project construction phase management, According to the nature and characteristics of each participation units in the project construction process, the project is setted clear division of three levels which are decision-making, directors and homework layer. Concurrent engineering thoughts which emphasize mutual cooperation and harmony among the owner, design units, construction units are used in the project construction phase management and coordination. The construction process parallel crossover is obtained by establishment of multi- professional team. Based on those, the parallel management organization framework on construction project of Daming place national the project is constructed; According to the project's characteristics that construction schedule is tighten and the design and construction have to synchronization, by processes sorting optimization theory , the design and construction of fourteen doors of five walls are sorted. Results showed that the total project period two days off back by the sort of wall and door which lies the south project and locates in the key circuits, and the late must start time of the rest of the walls is delayed, for other units leave plenty of time to design and construct the wall and door, as well as is provided favorable channels for large mechanical equipment into internal park to construct.The results indicated that the parallel management thought and parallel processes sorting optimization theory are used in the construction and management of large project by government investment, not only able to established reasonable organization framework which can meet such engineering's requirements, but also can solve such engineering project's multi-project sort. It conductive to management unit reasonably arrange the order of single engineering design and construction ,can reduce the conflicts of engineering construction, and reduce the massive labor mobility damage, thus saving cost, speeding up the construction progress, good social and economic benefits can be obtained. The result of this paper can provide reference for the similar project's management.
