Problems solved by technology

In terms of data formats, BIM software is diverse, and the software data formats are numerous. Due to the lack of a unified and open data format, it is difficult to ensure the data circulation between various software and to maximize the value of data.
On the other hand, in the implementation process of process construction, it is necessary to deal with a large amount of complex engineering data information, how to effectively organize and use this information, and realize the information exchange and communication between various units related to engineering projects and different professional application systems. Sharing is also a difficult practical problem
Since the BIM data accurately and detailedly displays the external and internal models of the building, the original design model retains a lot of information in the design process, making the model large in size. After integrating multiple professional models, the volume will increase by orders of magnitude , the requirements for hardware will be very strict, resulting in the performance of BIM data in usage scenarios to be improved
