Abstract
Introduction: The paper presents a methodology for reduction of expenses within investment projects aimed at the preservation and development of cultural heritage sites, based on the combined use of methods of scientific restoration, laser scanning and information modeling, as well as creation of a library of unique BIM elements of ancient city buildings, identified at protected sites of the urban environment, using restoration of a building in the Old Tatar Quarter (Staro-Tatarskaya Sloboda) in Kazan as an example. Methods: The authors performed standard (traditional) scientific restoration activities and innovative field studies using laser scanning and built a parametric information model of the cultural heritage site for further development of a restoration plan with account for site adaptation to modern functions. Results and discussion: Point cloud processing is carried out to create an information model and a library of unique BIM elements, which can be used repeatedly in restoration and reconstruction, thus reducing costs for BIM-model development in future investment projects. The practical significance of the study lies in the creation of a public good — a library (encyclopedia) of ancient architectural elements in the form of a library of BIM elements for BIM models of architectural and urban-planning landmarks in the region, as well as in the development of recommendations (by individuals, regional and local regulatory authorities) for an efficient policy in urban planning and restoration with regard to similar historical and cultural, architectural and urban-planning landmarks.
Highlights
The paper presents a methodology for reduction of expenses within investment projects aimed at the preservation and development of cultural heritage sites, based on the combined use of methods of scientific restoration, laser scanning and information modeling, as well as creation of a library of unique BIM elements of ancient city buildings, identified at protected sites of the urban environment, using restoration of a building in the Old Tatar Quarter (Staro-Tatarskaya Sloboda) in Kazan as an example
Use of laser scanning Based on a set of works on the scientific restoration of the cultural heritage site, performed by restoration architects, the authors set a task of studying the site using surface laser scanning
Considering the high cultural value of unique BIM elements created by restoration architects for ancient mansions, natural, cultural and historical monuments, the authors suggest implementing a regional investment project to create a library of unique BIM elements of cultural heritage sites located in the Republic of Tatarstan and developing measures of state support for the creation of such library as a public good with free access to it for the generations of restoration architects, historians, and art experts, based on repeated use of BIM elements for artwork, restoration and reconstruction of cultural heritage sites, including typical housing development in the historical part of cities and villages of the region
