Abstract:
Water conservancy projects are usually complicated and comprehensive.In that the hydraulic buildings are always complex in structure and different in shape, using virtual construction based on digital model and optimizing design in advance for the final hydraulic building is the most popular method in the design process of hydraulic structure. During the construction process of the Kaleta Hydropower Station Project, the parametric model is used to optimize the building design rapidly.Through a secondary development on those component templates, parameters and frequently-used API, we can integrate the parameters into editable documents, thus realizing the bidirectional drive between model and documentation.Furthermore, we can retrieve the template in line with the design requirements from library as needed.The program can automatically associate different parameters to the model, and generate the required model in one step.An example library collecting all well-designed models can provide reference for similar project.Based on models with different depth of detail, the collaborative platform can also realize the version control of models and deepening design as needed on construction site.Also, models and data can be extracted in assisting technical, site, schedule and cost management, which produces the final completion model.Last but not least, the completion model can be integrated with operation and maintenance information to facilitate the operation maintenance management.

Abstract:
All MBF student groups should work together for a BLC innovative integrated design for the Jilin Jianzhu University Museum of Urban Architecture. The purpose of this study is to explore how Building Information Modelling (BIM) will improve the existing out-dated production relationship. Advanced production relationship and production tools are integrated innovatively to transfer traditional design process and construction management method, to realize intensive project management, also to satisfy all project stakeholders, and to achieve a final success of the project. PMBOK is used as the guideline during the life cycle of the project, and the Pre-FM enables the owner to collect requirements and monitor the project progress. Through deliberate discussion with the design and construction companies, the owner decides to use BIM, and apply IPD contract, to coordinate the relationship between project units and to implement project integration delivery. The parametric results of BIM collaborative design are delivered to contractor for further processing in order to guide the project construction. The Post-FM accepts the as-built model, which is used in the later stage of operation & maintenance management, to achieve a life-cycle application for the project.

Abstract:
The Building Information Modeling(BIM), possessing powerful architecture digitizing capability, has been increasingly applied in construction fields and processes during the life cycle.In the architecture designing process, the building information model should be modified several times before perfectly forming a complete project design scheme, and those modification information can provide references for the optimization of the design scheme.However, Revit can not provide detailed recordings or eligible traces of those intermediate state information.In order to achieve all-the-way tracking and improve efficiency of the model modifications, this paper presents a version management scheme of building information modeling based on event monitoring mechanism.Research shows that such a version management scheme can effectively track modification information of various model versions, which facilitates the management of building information modeling.Meanwhile, the version management scheme adopts the mechanism of merging operation information to clear the redundant operation of the same object, which shortens the execution time of the model from the initial state to the target state, and plays a significant role in acceleration.

The Public-Private-Partnership projects have been greatly developed in recent years. Generally, in ourcountry, the role of public partnership is always undertaken by the government. Therefore, the project is gaining both the advantages of the policy and the technical and financial support of the social professional enterprises. However, the PPP project also rises high requirements on cost control in theconstruction, operation and maintenance process. Hence, the cost transparency, and visualization and simplicity of management will all be the key points to the success of the PPP project.This paper mainly discusses the application strategiesof BIM technology in PPP project, and the economic benefits of the application.
