Abstract:
Building Information Modeling sets up the building model based on the various relevant information and data of construction projects and simulates the real information of constructions by digital information simulation. The modeling is visualized and coordinated and can be imitated, optimized and plotted. Yong Li International Financial Center Project is a typical super high-rise building with core tube and steel structure inside. Its mechanical and electrical engineering contains chilled water, ventilation, electric, drainage, fire protection and so on, and the traditional method could not meet the detailed design need of the project, thus, BIM technology is adopted to deepen the design in the specialty. In the application of the technology, the team of this project continues to innovate. Bearing the idea of " BIM + " in mind, the team has found many new technologies for construction management, which greatly improves the whole management level. The article mainly introduces the implementation of BIM in this project.

Abstract:
As a key technology in recent years that brings about the reform of the building industry, BIM has been recognized and applied in the whole-process management of construction and production. Based on the BIM application in the whole life-cycle of the construction stage of the electromechanical engineering of the Scientific Research Center of Yanchang Petroleum, this article comprehensively analyzes such BIM application points as collision detection, 3D roaming, 4D construction simulation, 5D cost control, 2D code and MT application, factory prefabricated of material components and in-situ assembly. The application results show that the application of BIM technology in this super high-rise building not only relieves the vertical transportation pressure faced by most super highrise buildings but also brings about significant reform to the in-situ construction management, which greatly improves construction efficiency, avoids rework waste and realizes zero-waste of key material and equipments. Meanwhile, BIM also provides precious experiences and practical data for the collection and improvement of company data, the exploration of trainings for BIM professionals, the draft and amendment of company BIM standards, and the development strategy and planning for the BIM team, which transfers companies to be technology-leading.

Abstract:
The rapid development of urban underground rail traffic, especially such problems as complex geological conditions, too many pipeline layout and the impact of the surrounding environment emerging in subway station construction process, often lead to the difficulty in station construction. Therefore, reasonable construction scheme is critical for the efficient construction safety of the station. In this article, according to the actual situation of Shenyang Metro Line 9 Shen Su Xi Lu metro station, a station model is established by using BIM technology. Based on simulation of two selected plans and in consideration of geological conditions, the construction schedule and cost, the article simulates and analyzes station open cut construction process and concludes that "bi-lateral step method" is more reasonable. At the same time, the article analyzes the advantages of BIM technology in Metro construction. The case study shows that the BIM technology and the bilateral step method have broad application prospects in the construction process of subway station.

Abstract:
With dynamic two-dimensional code as its joint, BIM-QR system is composed of Tekla structures steel structural BIM model, a background server and mobile terminal. The BIM-QR system can upload mass information to the server. Then we can extract, gather, analyze and manage the information according to the demand, providing information management for the whole process, such as raw material purchasing, component production, component transportation, component quality acceptance, etc. This system is helpful for us to reduce the human input and is conducive to management. The dynamic two-dimensional code is to increase the encoding and decoding protocol proprietary protocol based on the two-dimensional code, so that the two-dimensional code can preserve both solid state information and dynamic information simultaneously. Using a mobile terminal to scan the two-dimensional code can quickly read the component information, and at the same time, the information of the import acceptance, plant acceptance, and the acceptance of installation will be uploaded to the server. The information is then updated to the BIM model through the Tekla Structures software plug-in. By changing the component in the model to change the color of the component in the display, it can reflect the different status of the component. The BIM model, mobile terminals and the backend server data are combined, by using dynamic two-dimensional code as the carrier. The construction quality acceptance management of steel structure is approached.

Abstract:
By the fine design of BIM and using a unified data source, the sustainability of the whole process of the design data can be maintained, the design can be optimized, and the design works can achieve the requirements of green building. Besides, digital simulation software are used to stimulate and analyze the lights, the winds, the environments, the load, and the personnel evacuation through Ecotect, Fluent, Abaqus and Pathfinder. The results of simulation can optimize building window, the building shading, the building aseismicity, and the evacuation of buildings and renewable energy utilization as well. This method not only improves the design quality but also ensures the design of safety and energy saving, and eco-friendly sustainability, which facilitates the library′s indoor and outdoor environment for both study and life, and thus realizes the harmony among human beings, the architecture and the nature.

Abstract:
Although the BIM technology has been used in China widely, the value that BIM technology produces is not fully reflected, because there is no uniform industry standard. This article mainly discusses BIM process standard from the perspective of software solutions, and uses IDM method to analyze the design process. The paper draws the process map of BIM -based collaborative design, uses the corresponding form to list the contents of activities and partial exchange requirements in the process map, and makes some IFC -based data description of partial contents of MVD. It cannot only help the designers to clarify the professional task and improve design efficiency, but also provide a reference for the development of the industrial BIM standard.

Abstract:
Shield construction technology is widely used in the construction of the subway engineering, but at present, domestic and foreign studies on shield tunneling parameters are comparatively less, among which most is about EPB shield. Research on multiple linear regression analysis of slurry shield construction parameters has become almost an empty field. Therefore, it is necessary to study multiple linear regression analysis slurry shield construction parameters to ensure the safety of the construction process and to reduce project cost as well as the adverse impact of subway construction. This article takes the example of the 757 to 1460 of the left line of shield construction data of Wuhan metro line 4, uses SPSS statistical software for statistical data analysis and establishes the multiple linear regression models of the total thrust and torque. The multiple linear regression models can be used to predict the total thrust and torque of the construction. With the right line shield construction field data for engineering verification, it is found that the predicted results are in good agreement with the actual results.

Abstract:
This article analyzes the problems of centralized management of the design process files in the design process management system of railway. To avoid the influences of frequent graphic files transmission on efficiency in the management process of railway design, this article provides a solution for the centralized management of railway design drawings by dynamic comparison, automatic differential archiving and transmission. It explores the implementation method, which is proven feasible by practices.
