Based on BIM technology, 4D simulation construction can put forward a virtual construction scheme, which can pre-process various possible induced situations in the construction. The application of BIM technology in the construction stage can reduce possible errors in the process of information transmission and reduce rework.Combination function is to encapsulate various algorithms into small functions one by one, for example, if level A is used, encapsulate a small function, if level B is used, encapsulate a small function, and so on; The following code:
