Abstract:
The BIM Technology is already widely applied in the construction of complex railway projects. For the promotion of integrity and effectiveness of information sharing and exchange in the whole life cycle of railway projects to ensure the BIM data can be effectively utilized, this paper proposes an extension method of IFC standard for railway station building information model based on the international IFC standard. After fully understanding the inheritance relationship between IFC entities, the authors add new entity classes to the IFC standard framework, apply transformation tools to obtain new entity class files, and finally verify the feasibility of the IFC data extension method on the NMBIM collaboration platform.

Abstract:
At present, Revit has great problems in the modeling of grid structure. The conventional manual modeling approach is almost impossible to complete, while adopting the conceptual mass modeling will lead to all the grid balls and bars the same type, which is not in line with the engineering practice. For solving the problem, this paper studies the modeling method of grid structure by using Revit Extensions and Dynamo software respectively, and focuses on introducing the application of visual programming tool Dynamo in Revit automatic modeling. For designers, Dynamo parameterizd tools are relatively easier to master. The Dynamo program developed in this paper can automatically generate an accurate grid structure model by reading data of grid structure. The size and location of the grid balls and bars are in accordance with the actual situation, and the efficiency of modeling and the quality of the model are improved.

By introducing the parametric BIM design platform, the problem of the twisted steel tower design of the bridge can be successfully solved by using the parameterized curved surface design function, and the collaborative design problems of complex steel structures of bridges can be effectively solved by the "skeleton + template" modeling method. The introduction of BIM technology not only laid a solid foundation for the successful completion of the bridge design, but also provided an accurate data model for the implementation of the bridge project and the operation and maintenance of the bridge.

Abstract:
During production and construction of pre-cast (PC) building components, normally a large number of different types of detection information are to be managed. Therefore, how to store, manage and share test data efficiently is a problem must be faced by the engineers. According to the classification and collection time of each measurement point, this paper establishes a corresponding database system based on the Revit development platform, to store the collected data in real time. The integration of detection information and the development of related functions are realized by using combined Revit and classes encapsulated by Revit API. Taking the information management of PC component sleeve grouting plumpness inspection as an example, functions of data interaction, point location and detection curve are developed to realize the timely sharing of the detection information of PC components, thus improving the interactivity between the detection information and the BIM model. Feasibility and effectiveness of the proposed method in this paper is preliminarily verified by the visual management of PC component detection information.

Abstract:
Based on a practical engineering case study, this paper concludes the deformation law during foundation pit construction of deep soil horizontal displacement, supporting axial force and ground settlement, through analyzing numerous field measured monitoring data. In the actual construction process, the deep horizontal displacement of the soil is increasing with the depth of the excavation, and the position of the maximum depth is also dropping, with the curve in shape of a big belly. The axial force of the supporting shaft also increases with the construction of the foundation pit, and the additional second support effectively relieves the axial force of the first support. However, the axial force of both supports increases at a rapid rate until the completion of project. Both the surface subsidence and the displacement of surrounding pipeline also keep increasing with the construction progress. The conclusion of this paper can provide references for similar projects.

Abstract:
Since the enactment and implementation of GB/T 50378 of Green Building Evaluation Standard, the green building has been developing rapidly in China. Nowadays, with the continuous updating of standards, new technologies, new products and new applications also emerge continuously, leading a better enforceability of green buildings. In the developing process of green architecture, the development enterprise will pay great attention on controlling the incremental cost. However, limited by the specialty knowledge and understanding deviation, there is a certain misunderstanding about incremental cost of green building. This paper explains how to calculate the incremental cost of green building correctly from the perspective of green building declaration, so as to guide people to look at the incremental cost of green building objectively, and also to be beneficial to the benign development of green building.

Abstract:
The Aluminum formwork, with its full name of the building Aluminum formwork system, is a new generation of formwork support system. The application of aluminum formwork system in the construction industry has improved the overall efficiency of the construction industry, and saved much consumption in the construction materials and labor expenses. The development in design phase and application in construction phase of aluminum formwork, is a major development in the construction industry. However, applications of the Aluminum formwork on site, which requires the formwork joins tightly, encounters difficulty in design modification. This paper investigates the optimal construction order by using the artificial intelligence algorithm to save time, as well as to reduce the probability of error by simulating the construction method in the virtual environment.
