Abstract

Project one：The Olympic Central District is the main venue for the Beijing 2008 Olympic Games.Its construction is the embodiment of the upgrade of Beijing's urban functional area.Project two：The construction of a new city presented by construction of the Beijing City Sub-center.The two projectsy are important cases in the development of China's cities.BIG（ Beijing Investment Group Ltd.，F(xiàn)ormerly Beijing Xinao Group Ltd.）is the core operational role of implementation of these two construction projects.In particular，it has carried out multidimensional research and exploration in urban land development，infrastructure construction，functional area construction and operation，urban development planning，and has continuously innovated and practiced.The results and comprehensive summaries of these studies are a sample for the development and construction of urban development in China，as well as empirical summary based-on innovation.It refines the experience of land development，construction organization，and management innovation in management systems and operational methods within this book.

The perspective of exploration of land development model.To resolve the disadvantages of the traditional land development model，BIG has created the“Three Unification Model”，which is planned，implemented and operated as one unified system.By using the “Three Unification Model”there are several key projects for land development in Beijing have been invested and constructed.For example，the Olympic Park Central District，the Olympic Sports Culture Park，the core area of Tongzhou New City Construction，and the core start-up area of the Beijing City Sub-center，etc.According to the unified planning of land level first-level project planning，implementation and operation，the comprehensive benefits of land-level development projects：economic，social and ecological benefits will be maximized.The effective promotion of planning has been achieved through the linkage between the government and enterprises.With the concept of smart city，planning has played a leading role in land development.Thereby ensuring the scientific organization and efficient promotion of land development throughout the life cycle of land development.

The perspective of practice in construction organization.For both Large-scale integrated functional area construction and infrastructure engineering management，building construction organization is complex system engineering.Implementation requires a comprehensive coordination of multiple entities and balancing of many factors.Combined with the practice of multiple projects，BIG summarized the“5A”safety and quality management methods，which are：All process management，All measure management，All weather management，All factor management，and All staff management，and the project management system of“full coverage planning and design guidance，comprehensive real-time dynamic information management，overall process quality control，full space-time security management，and early warning system”was established.It also summarizes the experience and practices in the establishment of multi-level matrix management mode of integrated project group and the integration of project infrastructure construction，and also refines the urban function area construction mode driven by infrastructure.

The perspective of management innovation.Relying on information technology，visual management systems established in comprehensive park management；virtual management technologies implemented in large-scale integrated project；the management efficiency has improved by information systems for safety and quality in large-scale integrated projects；the quantification of work tasks and data sharing has achieved through the multi-port cross-interconnection project management system between multiple construction subjects；The establishment and implementation of legal risk prevention and control system and archives management and information system，which suitable for large-scale investment enterprises and land development projects.Multi-angle management innovation provided a strong support for urban development.

China's urban development and construction is complex system.We are responsible and trying our best to find solutions to problems in a rapidly evolving context.
