Abstract:
For the design of the Suapiti hydropower station, the 3DEXPERIENCE platform of the Dassault Systemes is for the first time introduced to implement the forward collaborative design. During the whole design process, all BIM applications and design results are integrated on the 3DE platform by using ENOVIA, which ensures the most optimized and secured design results, improves the quality of design products, and forms continuous deliverable digital engineering assets. Combining with the secondary development of Composer, an information management system for design is independently developed to lightweight the BIM model for better management on the BIM model and related site design documents at the construction site, which will significantly improve the project information management capability.

Abstract:
The development of BIM technology has promoted a new revolution in the construction industry. With the deepening concepts of green buildings, intelligent buildings and urban sustainable development, the existing modeling methods can no longer meet the latest modeling requirements. In recent years, 3D real-time modeling technology has been widely used in model reconstruction of existing buildings. Thus, how to realize high-precision, fast-rate, low-cost real-life modeling becomes an important problem faced by numerous technicians. This paper uses the tilt photography technology to realize 3D real-world modeling. Based on an actual engineering case study, an implementable reference plan is proposed, and the real-world modeling method is used to monitor the settlement of the tunnel entrance.

Abstract:
To better improve the efficiency of design and construction integration of urban underground integrated pipe gallery projects, this paper analyzes the reason of lacking design and construction integration under the traditional mode from three aspects of information flow, professional collaboration and process management. Application of the BIM technology is able to optimize the whole progress of the design and construction integration, and three optimization modes are attempted to be established including the design coordination mechanism, the construction coordination mechanism and the design-construction integration mechanism of the integrated pipe gallery based on BIM technology. A case analysis is conducted to verify the feasibility of the design and construction integration coordination mechanism, which proves that the optimized modes is of great reference significance in realizing deep fusion of design and construction stages.

Abstract:
This paper studies a BIM-based virtual construction simulation system for large steel structures and its application in construction project. Environmental complexity, high requirement for operation and multiple potential safety hazards are the basic features of the construction for large steel structures, which are difficult to be considered thoroughly. Aiming at solving those difficulties, the virtual construction simulation system integrates Unity3d and BIM, which can fully utilize and visualize the information of construction design. It is able to help build a virtual construction site scene which vividly displays various circumstances, and can be applied for construction management, technical disclosure, as well as thorough check for potential quality and safety hazards. The system has been successfully applied in the large-span steel truss construction process of Hangzhou Shangcheng District Sport Center project, which evidently enhanced construction efficiency and fully guaranteed the quality and safety in construction process.

Abstract:
The BIM technology is the hot spot in construction industry today. Revit, as a main software in BIM, should be applied from early the design stage to achieve the "forward design". One challenge in the application is that the shop drawings should be created directly by using Revit to meet the requirements of relative standard after the completion of 3D BIM modeling. This paper compares the drawing function of Revit with that of CAD, and further discusses the difference. Advantages of Revit in shop drawing are concluded. This paper puts forward solutions to solve the difficulties in creating shop drawings including drawing broken lines, processing of redundant projection lines, and modifying axis number headers. The standard flow chart is also proposed considering the characteristics of Revit in creating drawings.
