The BIM model of the perinatal center was developed at two design stages: first, a digital information model of the existing unfinished building frame was developed at the stage of building inspection. Due to the use of a digital model, the examination was completed in one week. The second model was "dressed" for the survey data and represented the results of the design of the object and corresponded to the content of the project documentation. The model as part of the project documentation received a positive expert opinion.
