Abstract: The project of Shandong New Science and Technology Museum is characterized by unique project shape, with difficulties in construction, tight construction period, large scale of mechanical and electrical engineering, and exquisite interior decoration. The project adopts mixed steel structure, cast-in-place and prefabrication to meet the unique requirements of large space, large span and building shape. In the process of construction, there are some problems existed including complicated management and distortion of construction data. Therefore, through the application research of BIM Technology, this project has realized the construction of BIM model, the collision inspection and optimization of electromechanical pipelines, and the lapping of complex nodes of steel structure. At the same time, the intelligent construction system is also used to realize the transparent management of the project and promote the green management and intelligent construction of Jinan City.

Abstract: Taking the shantytown reconstruction and public rental housing construction project of Longshan County in 2015 as an actual case, this paper studies the application of the BIM technology in the construction of high-rise buildings. Clarifying that the construction difficulties includes large quantities of divisional works, strict cost control of steel, difficult treatment of karst cave of bored cast-in-place pile, and etc., a 3D model is built to generate scene animation and to improve the visualization effect. During the process of project construction, BIM-based measures are taken to solve the shortcomings of extensive and experiential management in the process of construction management of traditional projects, including the 3D visualization, professional deepening design and design synthesis, scheme simulation and optimization, engineering quantity statistics, three control and three management, refined management of reinforcement, supervision, and etc. The project management data then realizes informatization, refinement, visualization, and risk predictability management mode, greatly improving the management innovation concept and production efficiency. At last, in response to the construction difficulties, the corresponding solutions are proposed to simulate the construction deployment and progress, and to innovate the construction method, as well as to deepen the whole process control of design collision inspection, reinforcement refinement construction and platform control, which facilitates the technical disclosure, scheme selection and construction preparation, and further improves the research and application of BIM.

Abstract: The engineering Phase 1 of the rail transit Line 1 and Line 2 project in Hohhot is the very first rail transit project in China operated under the full-investment PPP mode in China, which considers the BIM technology as one of major means to implement informatized management. From the life-cycle application of BIM, this paper introduces the life-cycle BIM application system in details, including: the BIM application standard, the BIM data integration and management platform, the BIM application in all different stages of the project, and the digital asset delivery. Hence, a full set of life-cycle BIM application method is formed, providing guidance for the digital construction of urban rail transit.
