Identification, assessment of disadvantages and potential possibilities of implementing bim-technologies for modeling the renovation of unfinished building constructions projects

Problem statement. BIM processes are successfully used for new buildings, at that time most of unfinished building constructions (UBC) objects are not effective at BIM calculations. A review of the BIM references for unfinished building constructions and related renovation processes shows that numerous rapid changes and recent developments not only push implementation and research into many BIM-related fields, but also increase complexity of research. The purpose of the article. The article is aimed at identifying and discussing current trends and problems in the BIM-industry in case of modeling and calculating unfinished building constructions. However, implementation of BIM in the UBP is fraught with other potentials and challenges. The potential benefits of using BIM in FM appear to be significant, such as providing information, quality control, evaluation and monitoring, emergency management, or upgrade planning. Renovation and liquidation processes can also benefit from structured, up-to-date construction information to reduce errors and financial risk, for example through planning and consistency, costing, optimization or data management.A further process of selecting type of renovation may also benefit from the use of BIM by improving the decision-making process, reducing the costs of selecting a type of renovation, job security, expanded documentation, data management and visualization. But incompatibilities are still a major barrier to data-BIM. Conclusions. Practical approaches demonstrate the need to use BIM for unfinished building constructions. BIM development should also include owners, facility managers, designers, and related consultants who are unlikely to have been involved in the development of BIM functionality to date.
