The BIM+ management platform is a BIM integrated management platform based on IFC model, cloud technology, GIS technology, and Internet technology. It is a project-level platform built by various constructors in the infrastructure field. The system takes the project as the management unit and the construction process. To manage the core, the model data in the design and construction phases are integrated and managed through the platform to provide end users with powerful, intelligent, efficient, and precise management methods.
The BIM+ management platform is closely integrated with the existing construction management model.

Detailed description of openBIM on the project
IFC data storage standard solves the problem of data sharing and exchange. By using multi software platform, all professional designers can choose the most suitable and excellent BIM professional software for BIM design. In the process of design, they can clearly and accurately express their professional intention, generate three-dimensional models, and generate the required two-dimensional CAD drawings through BIM software. The 3D model expresses the designer's own design intention, and the modification of the design intention is completed by himself.
Through the IFC international village living standards, combined with fsdi-bim series design software, the model and data of various disciplines are connected. Architectural designers choose SketchUp software for architectural scheme design, and Revit and fsdi-bim software for construction drawing design; structural engineers select excellent yjk or PKPM software for structural analysis and design, and Tekla software for steel structure in-depth design; water heating electricians choose fsdi-bim and magicad software for mechanical and electrical professional design and deepening. The biggest characteristic and advantage of these professional BIM software lies in its specialty. In addition, compared with the software in a single software platform, fsdi-bim series software has high compatibility through secondary development, accurately expresses the designer's intention, and does not need a third party to carry out mold turnover.
Fsdi-bim Research Center has carried out in-depth and systematic research, and finally found that the problem is that when different professional software input IFC model file output from other professional software, there are problems in the component type analysis of non specialty. In order to solve this problem, the BIM Research Center has carried out a lot of basic research around IFC standards, and independently developed fsdi-bim series design software. From version 1.0 to the latest version 4.0, the BIM research center can analyze the IFC output of various professional software without damage The model file not only realizes the data exchange between various professional software, makes the data information from planning, design, construction to operation, maintenance and management, but also improves the cooperation efficiency. Moreover, the speed and accuracy of collision inspection are close to the international level. It can also realize the efficient communication and exchange between the project team members through the Internet for review and annotation. Fsdi-bim Series Design Software 4.0 can run smoothly on most desktop computers and laptops, greatly reducing the threshold of BIM application and promotion.

Benefits from using openBIM
- Interoperability: for the digital transformation of railway and Construction Asset industry, good interoperability has been achieved, which saves a lot of time for professional collaboration..
- Openness: Based on the IFC model neutral standard, it promotes the open connection between different professional and different software, and saves a lot of development costs.
- Reliability: IFC data exchange is based on independent quality benchmark and has good reliability.
- Collaboration: the design and construction workflow should not be restricted by proprietary processes or data formats.
- Sustainability: it provides a sustainable technical support foundation for the construction of smart city, helps the continuous development and improvement of fsdi-bim series software, and saves costs for subsequent development.
"We were able to innovate using openBIM."
Based on the standard format of IFC data, establish a standard data expression and storage method, so that all kinds of software can import and export the data in this format, so as to promote the data sharing between different specialties and different software in the whole life cycle of the project. The format of information generated by different types of software is unified by using IFC Standard to realize the free conversion of building information.
IFC Standard expresses various kinds of information through a hierarchical and modular framework, which can be divided into resource layer, framework layer, sharing layer and domain layer from bottom to top. Each of these layers contains many modules. Each level can only refer to the information resources of the same level or below, but not to the resources of higher level. By stipulating this information reference rule, the lower level resources are not affected by the changes of upper level resources, so as to ensure the stability of information.
Ifcxml is published as an XML schema definition (XSD) derived from the IFC express model. Ifcxml includes ex.xsd And ifc2x2 FINAL.xsd : ex.xsd General schema of all translated express models, including data source and definition of general data type after translating express data type; ifc2x2 FINAL.xsd Refers to the ifc2x2 specific serialization unit and contains all the XSD definitions of IFC specific classes, relationships, properties, and data types. The property set definition (PSD) schema provides an extensible markup language (XML) schema definition for defining information such as applicable IFC entities or types, as well as properties and attribute sets outside the IFC specification. In addition, a mapping is defined to transform the content of IFC defined attributes into other applications.
Through the use of IFC international storage standards, combined with fsdi-bim cloud platform, realize the BIM application function of mobile app，based on microservice development pattern，Adopt JAVA language development，using relational database Mysql+MongoDB,Object-oriented development，adopt B/S architecture.
"We were able to identify where we need openBIM to develop further."
(1) Strengthen IFC's support for infrastructure. Develop a new generation of IFC standards to fully support infrastructure such as roads, railways, bridges, ports, tunnels, airports, etc. The application of openbim is mainly concentrated in the design and construction stages of buildings. The lack of support for the infrastructure section limits its further application. Therefore, IFC is extended in the actual application process.
(2) Continuously develop and upgrade software supporting IFC standards. With the constant upgrade of IFC Standard Version, develop and upgrade the software tools supporting the corresponding IFC standards, so as to better realize the functions of IFC. The software has the problem of data loss in the process of parsing IFC file. In the process of acquiring and transforming the standard, the information in IFC data model can not be fully analyzed, and part of the data will be lost. The extra data input increases the difficulty of its application. With the increase of model complexity, data processing becomes more difficult, which hinders the large-scale data exchange.
(3) Research and develop the integration method of openbim and other emerging information technologies. To achieve better integration of openbim with GIS, IOT, laser scanning and other emerging information technologies, and better serve the engineering. Gradually meet the requirements of multi-scale, real-time, fine and other aspects of the actual project.
In short, as a solution to the problem of interaction and sharing in the construction field, the fsdi-bim series software based on openbim has played a great role in the practical engineering application. With the continuous development of openbim, it provides more comprehensive solutions for the interaction and sharing problems in the construction field.
