BIM on all stages of the life cycle of the building
To achieve the maximum effect from the use of BIM-technologies, it is necessary to implement them at all stages of the project implementation, to be a full-cycle company. In this case, the model lives from the concept to the commissioning of the facility and is subsequently transferred to the building owner as the basis for the creation of the operational system. In the article the enlarged stages of the life cycle of an object are considered: design, construction and operation. Thus, it becomes obvious that when using BIM, the scheme "alone did the model - others use it" is too simple and does not correspond to reality. It is more correct to say that at each stage of the building's life cycle, its information model obtained from the previous stage is modified and supplemented taking into account the specifics of the new activity, and the process of information modeling continues. That is, BIM is a continuous process throughout the life cycle of a building object.
