Study on Integration and Management System of Schedule in Large Complex Construction Engineering Projects Based on Lean Construction

There were many phases, hiberarchies, activities and partners in the schedule of construction engineering projects, especially the large-scale construction engineering projects, and the activities were complicated, the processes were very difficult, which has high impact on information communication between each partners, accordingly, the schedule would be out of controlling, the cost would be increased, and even the quality would be not satisfied with the owner. On the basical theory of Lean Construction and multistage plans of construction engineering project, Integration and Management System of Schedule in Large Complex Construction Engineering Projects (IMSSLCCEP) was proposed. It was studied from the data flow,hiberarchy and functional model. Finally,the cases of applying of IMSSLCCEP were studied, which educed that IMSSLCCEP was an effective way for large complex construction engineering schedule management from whole angle.
