Within the project B.h.EN.E.F.I.T. it was necessary to explore the possibilities of using digital technology, in this particular case of BIM technology, for the effective management of historic built areas. The research was conducted on the building of the City Hall in Karlovac, which is located in the historic built area called „Zvijezda“. For the subject building a BIM model was created which contains a set of building information with the aim that this information facilitates decision making about the possible reconstruction or the reconstruction itself, but also the later maintenance of the building, at the same time enabling the participation of relevant stakeholders in the decision-making process and in the management of historic built areas without requiring extensive technical and professional knowledge.
