Abstract:
In recent years, more and more real estate development companies have realized the value and advantages of BIM technology in project management. But the BIM requirements of most projects are only based on individual technical cases, not integrated into the project management process. This paper takes the A1 tower of the Poly Yuzhu Project as an example, introduces a practice on owner / developer supervised BIM project management, and introduces its implementation benefits of quality management, schedule management, safety management, cost management and coordination management. The analysis and thinking of BIM project management in this mode can be used as a reference for BIM implementation of similar projects.

Abstract:
In recent years, the Building Information Model (BIM) technology not only receives rapid development in aspect of theory, but also has been widely used in the project practice. However, it is rarely seen that the BIM technology is applied to the research and practice of government technological or management revolution. In response to the policy requirements of Shanghai Municipal Government to establish a BIM-based government supervision model in the construction industry, this paper introduces the application of BIM technology in the Disney Toy Story project, which is located in the key core areas of Shanghai. Through the application of BIM technology, the efficiency and accuracy of completion planning acceptance has been improved. Efforts are also made on training the government working team with BIM ability, and on establishing a new BIM-based acceptance process, which plays an active role in building an open, transparent and efficient administrative examination and approval supervision system and improving the administrative efficiency of the government.

Abstract:
A complete BIM model consists of the models of multiple professions. In the BIM design of the electric- power industry, different professions are designed by using different platforms, and then all professional models are integrated on a public platform. During the process, data form different platforms need to be converted to the public platform. According to the requirements of Shanxi Electric Power Co., Ltd., this paper studies the data exporting from the structure-model to Revit. All information of 3D entities and tower segments is input into Revit through IFC files, achieving the integration of structural model with other professional models. Lastly, the paper also illustrates the limitations and shortages of data exchange using IFC files.

Abstract:
With the rapid development of the city, the land becomes more and more scarce. Especially for the mountain cities, it has to consider building the buildings on the rock slope, so it is of great practical significance to study the interaction between the rock slope foundation and the upper building. The finite element method is used to study the co-influence of the layer number of upper structure, rock strength and building distance on the internal force of pile raft foundation under the interaction, and comparisons are made with the conventional design method without considering the interaction. The calculation results show that the main stress of raft is considered to be less than conventional design, and the maximum principal stress is transferred from the center to the edge of raft. With an increasing number of superstructure floors, the contribution of the superstructure to the stiffness of the raft is increased, the adjustment of the stress of the raft is enhanced, the reverse force of the substrate diffuses around, and the stress distribution of the raft is even more uniform.
