The general contracting project of 3D parking lot puts forward high requirement for deepening design, collaborative construction and operation management. The project mainly focuses on the combination of the key content of each node with BIM technology organically to fully play its value. During the planning stage, the quantitative simulation analysis is carried out to ensure the rationality of site selection. During the design stage, multi-professional collaborative design is carried out to ensure the depth of design. Also, full pipeline optimization is carried out to ensure the net height of parking lots, and comprehensive structural stress analysis is carried out to ensure safety performance requirements. During the virtual construction progress, construction simulation, cost control and quality control cover all aspects of design and construction management, which ensures the successful implementation of the project. Based on the BIM model, secondary development is conducted to achieve the data transmission and information inter-connection between the hardware and software. The BIM-based intelligence parking management system improves the operation and comprehensive management level of the parking lot, and optimizes the technical and economic indicators of the whole life cycle of the project.

For the real estate development projects, this paper develops an enterprise-level integrated management platform based on BIM technology.With this platform, the BIM technology can be applied in the whole process, and collaborative management can be realized in design management, cost management, schedule management, material management, safety management and quality management. Through the works done in the paper, the authors has explored acollaborative management mode of design and construction integration based on BIM technology.

In this paper, development situation of BIM technology is introduced and the application of BIM technology in steel structure production and installation of the bridge of South loop railway is discussed.By the application of BIM, the workload of the preparation stage of the construction is reduced, and the work efficiency is improved; the cooperative work of all participants in the process of manufacturing and installation is enhanced; the construction simulation is conducive to optimizing the construction scheme.

Design of offshore wind turbine foundation involves multi-disciplinary fields and contains various subitems, so software is often needed to assist designing. On the other hand, marine engineering design software and finite element analysis software is not specifically developed for offshore wind turbine foundation, then make it very necessary to develop professional software. The design process and main contents of foundation design is firstly introduced, the software's main functions including load calculation, combination of load, pile analysis, foundation analysis and result output have to be developed to achieve the above requirements. The kernel modules contain visualization function, integrated designing, foundation input and reconfigurable computing. Then calculation methods and main principle embedded in software is introduced. Lastly application of software FDOW to design offshore wind turbine foundation is given with one practical project.
