According to the actual demand of housing project, by integrating BIM and 4D technology, the method of BIM modelling, program analysis and evaluation for housing program based on existing standard house type was put forward.Problems including associating economic and green performance information with 3D model of house type, management of house type model database, assembling house types into typical floor, formation of building, program analysis and evaluation on the foundation of economic indexes calculation and green performance analysis were solved, thereby coming with the BIM-based Housing Project Planning System based on Autodesk Revit 2012 and 4D project management system.The result of practical application illustrates that the approach for BIM modelling, program analysis, and decision making of housing project proposed in this paper was effective, which will promote the application of BIM in housing project planning.

BIM Server provides a solution for BIM to support construction life cycle. Currently, the structure of BIM Server is C/S, but gradually B/S also shows its advantages. The release of the HTML5 standard brings the WebGL technology which supports hardware graphics acceleration in browser and is one of a series of revolutionary Web technologies. Thereby the foundation is laid for achieving Web-oriented BIM information management and 3D display of BIM model. In this paper, the model information scope and its expression of Web-oriented BIM is analyzed, and the corresponding information management technology and the BIM model display based on the Three.js, which is a WebGL framework, are studied. Then, a WebGL-based platform for 3D display and information management of BIM is also developed. Application shows that the graphics platform of the platform performs stable with nice rendering for large BIM. Meanwhile the platform provides rich feature supports for Web client by favorable interactive functions, showing a great application value.

According to the key requirements in schedule and resource management during construction, an approach for schedule-resource trade-off problem was established based on 4 Dimensional Building Information Model (4D-BIM) proposed by Tsinghua. With the transforming mechanics between 4D-BIM and Discrete Event Simulation model, schedule-resource trade-off model can be achieved automatically. In addition, the paper explores and analyses the process of SA algorithm in order to tackle the schedule-resource trade-off. The whole solution was applied to a real project and illustrated a good result. The result indicates that the automatic schedule-resource trade-off modelling can free people from intensive work, and reduces repetitive work, which provides managers with a practical tool for schedule arrangement and resource allocation.
