Compared with bim technology, what are the disadvantages of traditional methods?

Let's talk about the application point of BIM first, that is, to understand the construction, get a concrete model and apply it to our construction. Our traditional method is actually to construct according to the drawings, but at this stage, most drawings will not consider other majors, and some complex nodes or pipelines can only be synthesized by our master on site, or by guessing, which will not only affect the progress, but also greatly increase the cost. On the one hand, on the other hand, in many aspects of traditional methods, we communicate point to point, but in BIM technology, we put all participants on a platform and use this model together. Through this mode, including some materials, or collaborative sharing, we can complete it on this platform. We don't need many people to sign the bill as before. Now it can be managed directly on the platform, and even if you don't meet, the work can still be completed.
