1. Reduce disputes

　　Traditionally, architects and owners discuss architectural design schemes on the design drawings, which may cause blind spots in communication and understanding. As for the three-dimensional information model generated by BIM, all design conditions are parameterized. The content of the parameters forms another alternative. The architect and the owner can have a thorough discussion and select the most suitable design plan. The position of the two parties will be changed from confrontation to collaboration. The communication becomes clearer and more transparent, reducing the design plan in the mid-term. The opportunity to modify or reverse the case.

　　2, the span of work area

　　The work content in the past is always clearly divided. The work content between architects and civil engineers is clearly divided, and discussions are always carried out after a stage. It is impossible to discuss changes anytime and anywhere, and it is not easy to distinguish the interface between each other. As a result, it is possible that both the architect's drawing and the structural engineer's drawing are correct, but after putting them together, they cannot be combined, and it takes a lot of time to modify. But if the concept of BIM is used, architects and civil engineers can communicate on the same platform, use the same model, use the same language, and conduct two-way discussions. This kind of work is like a team and can achieve good results. Communication, the interface overlaps between disciplines are clearly connected, reducing the conflict of design content.

　　3, building information integration is consistent

　　In the past, there was a large amount of data. Various floor plans, elevations, structural drawings, etc. were all in different files. If you want to modify, always modify the files separately, and there may still be some slight errors after the modification. The correctness of the drawings can be ensured, but if the building information model is used, all the information is in the same model. If there is a design change, all the information will be changed automatically following the changes. Various floor plans, elevations, and The structural drawings will also be changed together, so that there is no need to correct them one by one, saving a lot of communication and correction time, and of course reducing the possibility of errors and omissions.

　　4, real-time information update

　　With this interface, it is more convenient to update the information. The supervision unit can directly use the ipad or mobile phone to compare whether the project has been constructed according to the drawings. If there is any incompatibility, mark it immediately, and the entire message will be transmitted. In the integrated interface of BIM, the structural engineer checks whether it affects the safety of the building and considers whether to change the design, which reduces the communication time. Traditionally, if there is an error in the check, the structural engineer has to ask the structural engineer with the construction drawing. And make a mark on the drawing, but also to discuss whether to modify the design, if necessary, may also find an architect, the process is quite trivial, which shows the importance of the platform.

　　5. Resolve unclear dead spots

　　In the past, two-dimensional graphics were used to describe design drawings. Some visual blind spots are difficult to communicate or even cause misunderstandings, resulting in inconsistencies between the site and drawings after construction. If BIM three-dimensional building information models are used in the architectural design process, the three-dimensional space can be clear Interpret the design drawings to reduce misunderstandings on communication, and easily detect conflicting sections in the design time, such as pipeline conflicts, steel reinforcement conflicts, etc., and improve them so that problems are not discovered until after construction, and responsibilities can be clarified.
