PRINCIPLES OF PROTECTION AND USE OF CULTURAL HERITAGE SITES IN TERMS OF ECOLOGICAL OPTIMIZATION OF RESIDENTIAL AREAS

The article investigates the principles of protection and use of cultural heritage sites in terms of ecological optimization of residential areas. The concept of cultural heritage object is defined and the order of definition of protection zones of cultural heritage objects in the conditions of ecological optimization of settlement territories is established. The principles of formation of the status of a cultural heritage object are revealed and the legislative basis is described. The concept of "territory of cultural purpose" is separated. Describes the problems of protection of cultural heritage sites, the main of which include the complexity of the content of objects, the search for the necessary funds for restoration, to solve which it is necessary to attract external sources of funding other than the state. The generally accepted ways of solving the outlined problems are given and the principles of their realization are substantiated, namely the necessity of complex application is emphasized. The classification of the process of reconstruction of cultural heritage is presented, the main directions of which include: restoration, regeneration, revitalization, revaluation, improvement and new construction. Each of these classes is described according to the method of implementation on site. It is emphasized that the protection zones of cultural heritage sites are areas adjacent to the included in the register of monuments and ensembles, and within which, in order to ensure the preservation of cultural heritage sites and compositional and species links, the construction of capital construction projects and their reconstruction related to changes in height, number of floors, area, except for construction and reconstruction of linear objects. The boundaries of the protection zone of the cultural heritage object are structured according to the zones of location of the latter. The directions of the relation of the state supervision in the field of protection of objects of cultural heritage to the principles of realization of the state support are defined. The list of possible measures of influence of citizens and legal entities in the field of protection of cultural heritage objects in the conditions of ecological optimization of settlement territories is offered.

Estimation of the Load-Carrying Capacity of the Constructions of the Cultural Heritage Object «The Oldenburg’s Complex. Lovers Bridge. 1900»

Постановка задачи. Многолетняя бесконтрольная эксплуатация моста привела его несущие конструкции к аварийному состоянию. Для дальнейшей его безопасной эксплуатации требуется конструктивное укрепление практически всех элементов. Так как их прямое упрочнение невозможно без нарушения подлинного облика, авторы поставили перед собой задачу косвенного усиления конструкций путем подбора на математической и физической моделях допустимых схем и предельных значений нагрузок на пролетное строение. Результаты. Для решения поставленной задачи проведены и проанализированы результаты качественных и количественных теоретических исследований объекта культурного наследия «Комплекс Ольденбургских. Мост влюбленных. 1900 г.». Осуществлено инструментальное освидетельствование памятника, выполнена и испытана лабораторная модель подлинного сооружения. Выводы. Полученные в результате всесторонних исследований данные позволили оценить ресурс несущей способности конструкций объекта культурного наследия, проанализировать возможности загружений пролетного строения моста и сделать заключение о его надежной эксплуатации в современных условиях. Statement of the problem. Many years of uncontrolled operation of the bridge led its supporting structures to an emergency condition. For further safe operation of the bridge, structural strengthening of almost all elements is required. Since their direct strengthening is impossible without violating the original appearance, we set the task of strengthening the structures indirectly by choosing permissible schemes and limit values of loads on the span on mathematical and physical models. Results. To solve this problem, we carried out and analyzed the results of qualitative and quantitative theoretical studies of the object of cultural heritage «The Oldenburg’s complex. Lovers Bridge. 1900». We carried out an instrumental inspection of the monument, designed and tested a laboratory model of the original structure. Conclusions. The data obtained as a result of comprehensive studies made it possible to assess the load-bearing capacity of the structures of the cultural heritage object, analyze the possibilities of loading the bridge span and make a conclusion about its further safe operation in modern conditions.

Redevelopment of the cultural heritage object (the case of the “Nurov’s Estate”)

The problem of redevelopment of cultural heritage sites is relevant and in demand all over the world, because such spaces carry the history and spirit of not only a particular place, but of an entire city. Many international and Russian researchers note that the revitalization and development of such sites will help to preserve the history and heritage of the city. In addition, there are many examples of the successful implementation of redevelopment projects and the creation of relevant and popular spaces on their territory. In this article we consider the project for the redevelopment of the Nurov Estate ensemble, located in Ekaterinburg (Russia). The project was carried out in cooperation with the owner of the object (development company) and is based on the concept of Art-cluster. For this project were calculated and considered indicators of commercial efficiency of projects.

THE FEATURES OF PUBLIC SPACE FORMATION WITHIN CULTURAL HERITAGE AREAS OF INFLUENCE

The authors consider the problem of formation of open public spaces within areas affected by the influence of cultural heritage sites. The focus here is on the historical center of Krasnoyarsk city. Relevance of the research is determined, on the one hand, by the current trend for the formation of comfortable urban environment in public open spaces. On the other hand, by the appearance of numerous implemented projects, including those in Krasnoyarsk, which have identical functional and objective content, detached from the cultural and historical context of the environment. The analysis of the “Map of areas with special land use requirements related to the protection of cultural heritage objects” in the historic center of Krasnoyarsk revealed the following characteristic morphotypes of public open spaces (genesis types) within cultural heritage areas: territory adjacent to a single cultural heritage object (protection zone of a cultural heritage object), which is part of the street; territory adjacent to a single cultural heritage object (protection zone of a cultural heritage object), which is inside the development area (yard, courtyard garden, manor house); a street formed by the facades of several cultural heritage objects on one or both sides; a square or a garden square, which is part of the architectural ensemble – an object of cultural heritage; the territory of the quarter formed by a group of cultural heritage objects, and which is a cultural heritage protection zone; a park or square within the protected historic green space. Each type is analyzed using examples, survey of protection zones of cultural heritage, the established urban planning regulations within their boundaries regarding the availability of requirements for the improvement of public open spaces. The authors touch upon the problems of landmark attractions, preservation of identity in the historical and cultural environment of the settlement. They also formulate the principles of public open space formation within influence areas of cultural heritage objects on the basis of various methodological approaches approved by the Department of Urban Planning within the School of Architecture and Design of the Siberian Federal University.

Age as a criterion of value for tangible cultural heritage objects under Russian law

UNESCO’s activities are dedicated to the conservation of both intangible and tangible cultural heritage. One of the most difficult issues in constructing a system for the protection of tangible cultural heritage objects is the criteria for identifying objects as cultural heritage. Obviously, it takes time to assess the cultural or historical value and significance of a tangible object. In most cases, granting the status of a cultural heritage object is assigned much later than its creation. However, international acts also do not contain specific requirements for how old a particular object should be in order to qualify it as an object of cultural heritage. UNESCO’s practice is known for several cases of adding to the World Heritage List relatively young sites. The Russian Cultural Heritage Object Act (2002), along with the laws of some other countries, establishes a specific age (40 years) that any object must reach in order to become a cultural heritage object. An exception is made only for memorial apartments and buildings (they can be attributed as objects of cultural heritage immediately after the death of famous personalities) and for objects of archeology (they must be at least 100 years old). This rule of law is mandatory, which means that it does not make other exceptions to the rule of 40 years. Such a rule of law significantly distinguishes the Russian approach from foreign legislation. On the one hand, such regulation may negatively affect the possibility of protecting outstanding objects from the late Soviet and early new Russian period. On the other hand, the approach of granting the status of cultural heritage objects to many relatively new objects can negatively affect urban development. The author proposes to evaluate and review this provision of law in order to find the optimal balance of public and private interests.

Monitoring of Immovable Cultural Heritage Implementing 3D and Artificial Intelligence Technologies

Preservation of immovable cultural heritage is one of the main challenges for contemporary society. Nowadays very often organizations responsible for heritage management constantly have to deal with lack of resources, which are crucial for proper heritage preservation, maintaining and protection.The possible solution of these problems could be automated heritage monitoring, based on the 3D and AI technologies. 3D scanning technology is the most accurate method to capture the situation of an evolving cultural heritage object or complex at a given time. As a cultural heritage object or complex is evolving continuously, AI based comparison of two 3D point clouds created at different time allow to reliably trace potential changes. Proposed solution is realized by project financed by Research Council of Lithuania „Automated monitoring of urban heritage implementing 3D technologies”. The first results of the project are presented at this article.
