They generate files that consist primarily of vectors, associated linetypes and layer identifications.Then people make use of the divid

9、ed and fragmented to communicate. With these techniques were further developed, additional information was added to these files . Blocks of data make the building project more reasonable and standard. With the introduction of 3D modeling, advanced definition and complex surfacing tools were added1.

10、In the process of paper-based modes of communication. Errors and omissions in paper documents often cause unanticipated costs, delays, and eventual lawsuits between the various and divided parties in a project team. These problems cause friction, financial expense, and delays. Efforts to address suc

11、h problems have included: alternative organizational structures such as the design-build method; the use of real-time technology, such as project Web sites for sharing plans and documents; and the implementation of 3D CAD tools3. Though these methods have improved the timely exchange of information,

12、 they have done little to reduce the severity and frequency of conflicts caused by paper documents or their electronic equivalents. One of the most common problems associated with 2D-based communication during the design phase is the considerable time and expense required to generate critical assess

13、ment information about a proposed design, including cost estimates, energy-use analysis, structural details, and so forth. These analyses are normally done last, when it is already too late to make important changes1. Because these iterative improvements do not happen during the design phase, value

14、engineering must then be undertaken to address inconsistencies, which often results in compromises to the original design. Traditionally, construction practices are conducted in totally different programs that are not compatible. The engineers focus on their own area and work and use their own softw

15、are to conduct the engineering practices. However,there are the need to transform and use different data and information which are managed by different people from all area. As work softwares became more intelligent ,more users wanted to share data associated with a given design, the focus shifted f

16、rom drawings and 3D images to the data itself. Meanwhile,the error and inconsistency between every work party will be the main obstacles existing in the way to make use of data comprehensively. BIM allows the involved parts to make information into a unified data source. A building model produced by

17、 a BIM tool can support multiple different views of the data contained within a drawing set, including 2D and 3D. Through BIM, all parties can share the same data ,time is greatly saved ,the errors decrease,the engineering projects go more smoothly.With the development of information technology,it h

18、as been possible to make the construction informationization develop better and better.With more and more engineering constructions adopting the BIM, BIM has been a hot topic in building field. Moreover,BIM are showing more unique functions in current engineering construction.In western countries, B

19、IM has been applied to engineering extensively. In China today, BIM comes into engineer and architect in a rapid speed. However,what BIM is？1.2 The definition of BIMUp to now,there are not the standard definition about BIM in China. The National Institute of Building Sciences (NIBS) defines BIM as f

20、ollows: A building information model, or BIM, utilizes cutting edge digital technology to establish a compatable representation of all the physical and functional characteristics of a facility and its related project/life-cycle information, and is intended to be a repository of information for the f

21、acility owner/operator to use and maintain throughout the life-cycle of a facility.BIM is an emerging technological and procedural shift within the Architecture, Engineering, Construction and Operations (AECO) industry. Through abundant practices, the function of BIM has been expanded to a wider fie

22、ld.More and more new techniques are associated with BIM,which make BIM be a strong tool in different parts of building projects, especially in building lifecycle.BIM can accommodate many of the functions needed to model the lifecycle of a building, providing the basis for new design and construction

23、 capabilities and changes in the roles and relationships among a project team3.1.3 The definition of lifecycleFor lifecycle, it refers to the construction project related to the development, from the process of feasibility study, design, bidding, construction, rental operations, demolition.Chapter2

24、The value of applying BIM in the building lifecycle 2.1The advantages for applying BIM in designDesign is a team effort, involving the owner, the architect and specialist designers and engineers, and with growing recognition, others involved in the projects fabrication and erection. In traditional d

25、esign, a project may need to pass these processes, feasibility study, predesign schematic design, design development, construction detailing , construction review. This is a complicated process. If BIM is applied to this process, it will play a unique role .All the parts involved in the project can

26、continue their work in a union platform.2.1.1 VisualizationVisualization includes design visualization and schedule visualization. Design visualization allows the designer to compare various design options with a variety of materials, textures, colors and layouts. The 3D model generated by the BIM s

27、oftware is designed directly rather than being generated from multiple 2D views. It can be used to visualize the design at any stage of the process with the expectation that it will be dimensionally consistent in every view. BIM introduces renderings in 3D that provide a realistic representation of the color and texture of materials, which allows the designers to explore the model visually. Model rendering also helps the designer in
