The choice of aversion of the project proposal on restoration of the cultural heritage property on the basis of multicriteria comparative analysis

Abstract

With time a problem of preserving architectural heritage sites becomes more acute, since many unique listed buildings are in an emergency state and require the restoration measures that take into account the specifics of the historical environment, an analysis of the technical condition, evaluation of the monuments’ value, the possibility of their functional adaptation to modern needs. The search for solution to preserve such objects is often complicated by the development of a modern urban renovation area around them and by the difficulties of maintaining a complete historical appearance of cities when adapting listed buildings to the functions demanded in modern society. The article proposes an approach to choose the best version of the project proposal for the restoration of a cultural heritage property of regional significance. The building is designed in an eclectic style in the city of Tambov. 11 versions of the author’s project proposals for the restoration transformations are considered, which preserve the historical appearance of the building and various transformations of the internal volume and development options of the adjacent territory. 14 criteria are proposed to evaluate the qualities of versions. To select the best restoration version a scientific method of a multicriteria comparative analysis was used, which made it easy to compact a large amount of information about the object to a single quality parameter in the form of a synthetic indicator for each version. Simultaneously the weight factors of the criteria were established on the basis of expert evaluation obtained from the professional groups of various profiles: architects, representatives of the contractor, state supervisory authorities, the owner of the object, the tenant of the object.
