Research on Organization Integration System towards Large and Complex Building Projects-From Life Cycle Perspective

The paper took large and complex building project as research object, using concept of life cycle project management theory, we proposed the organization integration system is the key factor to the success of life cycle project management after analyzing the basic principles of integrated management, project complexity and characteristics of building project organization integration. Based on the above, the paper studied the design and realization of life cycle organization integration system for large and complex project and established a three-tier model. Finally, the paper took the construction & facility project of 2010 World EXPO Shanghai China which the authors participated during the entire process as an example, rethought its organization integration system from life cycle perspective and makes reference for other projects.
