As the number of prefabricated concrete buildings increases, BIM technology has been practiced more, and the combination of prefabricated concrete buildings and BIM now seems inevitable. This paper mainly introduces the overall application solution of Shanghai Nanxiang Chenxiang Road Station complex project BIM. Before the PC component is produced, the BIM model is applied for deepening design. Through the secondary development of Revit, the steel bar information is automatically exported and quickly input into the steel bar processing equipment to realize the digitalization and batch processing of steel bar. Before PC members enter the construction site, BIM disclosing is implemented to the complicated construction nodes of prefabricated cast-in-situ joint to reduce the site rework. In the process of PC component construction, the progress, quality, safety, business and other management based on BIM are carried out through the information platform independently developed to realize the deep integration of BIM technology and site management. The application shows that BIM technology in PC project plays a significant role in construction schedule and quality management and multi-participant coordination management.

The research applies the BIM technology to realize the engineering cost management, which establishes our technical scheme to realize the quantity calculation based on BIM technology in commercial lines. By comparing the current construction cost budgeting software and the connection deduction relationship of BIM components, the accuracy of BIM engineering measurement is verified. According to the engineering quantity list pricing rules, the BIM modeling standard based on engineering calculations and the interchange standard of the engineering quantity data of BIM components are summarized.

Shanghai Oriental Hospital renovation and expansion project is very complicated due to the demand of ensuring the uninterrupted operation of the old building, the large number of mechanical and electrical systems, the difficulty of construction coordination, and the high requirements of operation and maintenance management. The paper summarizes the process and results of the comprehensive application of BIM technology. This paper focuses on three phases of application, i.e. the critical BIM application in construction period; the BIM model transformation across different stages; and the operation & maintenance phase BIM in-depth application. Through the whole process, it delivered a digital twin of the hospital′s new building, which achieves the visualization of the process of the building′s big data and the flexibilities. Finally, it has concluded the problems during the BIM implementations and has forecasted the future perspectives, which offers method to improve the qualities of model delivery, to improve the quality of information, and to expend the scope of the BIM implementations.

Traditionally, operation and maintenance information for MEP mainly comes from completion data in the forms of drawings or documents.When the information is needed, it requires manual searches from such a huge amount of paper files.In order to realize the information transmission from design and construction phases to operation and maintenance period, effectively organization of such information by electronic means is the key issue to be resolved in current building lifecycle management.This can also enhance the information-aided maintenance.By introducing Building Information Model (BIM) and two-dimensional code, a BIM-based Facility Intelligent Management System (BIM-FIM 2012) is developed to realize the electronic integrated delivery of MEP, and to improve the maintenance management and emergency management of a building during its operation and maintenance period.The system also provides an effective way and platform to ensure the safe operations of all MEP systems.

In last ten years, building information modeling (BIM) has been rapid development. However, there are still few technologies and applications to support BIM data storage and sharing during building lifecycle. Therefore, a clouding-computing-based BIM data integration and service technology is proposed by this research. It adopts Hbase (a kind of NoSql database) to store massive BIM data on distributed nodes, which are integrated virtually by a clouding computing platform, so that all participants could get their required BIM data with a uniform interface. As one of its most import modules, a semi-structured BIM database is described in detail in this paper. By combing with attributes of Hbase and IFC model, the database addresses many problems, such as space waste due to sparse of IFC model, and lots of join calculations during information query. It's also more efficient and extensible than existed BIM databases. As a conclusion, this database sets a good foundation for clouding-computing-based BIM data integration and service technology, and is valuable for BIM application.

To overcome the shortcomings of commercial virtual simulation software including the need of high hardware configuration, expensive price and function shortage in secondary development, an OpenGL-based construction virtual simulation platform was studied and developed based on existed graphic engine of 4D-GCPSU. Its main features include reality rendering of 3D model by processing material, texture, lighting etc. 3D dynamic simulation and animation display with double buffer technique, creating and controlling of virtual scene with human-computer interaction technology. The platform has been applied and tested in practice engineering projects and can produce high quality 3D realistics model and 3D animations. It can be adopted in the development of 4D virtual construction and dynamic management systems. Therefore, the platform is of practical application value.

BIM technologies and tools are developed very fast these years, which provide an effective and efficient method to solve the "segment"problem in building industry. However, since data exchange is still mostly based on files, an integrated BIM containing all the information of multi-disciplinary can't be constructed, so that much value of a BIM is hard to achieve. For constructing an integrated BIM, this paper proposes a framework of the modeling technology for integrated BIM, which enables integrating information generated in difference phases dynamically. The framework includes architecture, modeling flows, deployment framework and key technologies needed to be solved. After that, a prototype system of BIM data integration and server platform (BIMDISP, a BIM Server) is developed. Then a real word project is applied in the BIMDISP to test performance of the modeling technology. As a conclusion, the modeling technology proposed is feasible to support integration, management and sharing of all the building information, so as to generate an integrated BIM.
