effectiveness, are untested, are absolutely contrary to international standards and guidelines that are relevant to this project. The mission recommends that the State Party be urged to avoid the use of wood preservatives, consolidants and chemical fillers due to their environmental impact, short period of testing, limited effectiveness and potential to reduce durability.
In order to sustain the Outstanding Universal Value of the Church, the mission recommended that the approach to the repair of individual logs based on gluing and patching be modified. The mission recommended that a revised approach needs to be set out and agreed as the Conservation Approach for the building.
The mission also considered that the conservation project is strongly oriented to technical solutions without any explicit relation to the Outstanding Universal Value of the property. The importance of authenticity of materials needs to be balanced with concerns about authentic form and design. All of this should be reflected in the Integrity and Authenticity sections of a retrospective Statement of Outstanding Universal Value.
Guiding Principles are needed that relate the conservation work to the key attributes of the property that convey its Outstanding Universal Value. Such principles will become increasingly important when they are needed to guide detailed decisions. The mission considered that it was essential for future decision making that Guiding Principles are developed on the basis of a Statement of Outstanding Universal Value and brought into the project. Concerning structural stability, the mission recommended that the State Party use the temporary supplementary structural support during the project and then remove it. The mission also recommended that permanent supplementary and reinforcing structure be added to the building only if absolutely necessary, and that structural elements should be reinforced as needed rather than installing general strengthening.
In order to protect the Outstanding Universal Value of the property, the mission stressed that project implementation must continue with no interruption. There is need to ensure that funding continues after 2014, as the overall restoration will not have been completed. The mission also stressed the need to prepare a capacity and skills building strategy with regular training courses involving those responsible for restoration activities in the Kizhi Museum Reserve.
The ICOMOS team during the mission prepared a set of guidelines for timber repair “Criteria for selecting log repair at Kizhi Pogost” to counter a presumption that maintaining authentic historic building fabric was the most important factor when deciding on repair methods. This was prepared to address the large numbers of individual repairs in single logs; the use of repairs which are not compatible with the shape, anatomy and natural characteristics of the wood and the use of adhesives, consolidants and other chemicals (some not yet tested).
The mission welcomed the monitoring reports reviewed, in particular “Wood-science monitoring of the Kizhi Open-air Museum Monuments” (Forest Research Institute, Karelian Research Centre, Russian Academy of Sciences, Petrozavodsk, 2009) and “Complex of land measuring on walls deformation monitoring of the Churches of Transfiguration and Intercession and the Bell tower on Kizhi” (Institute of restoration of historic and cultural monuments “Spetzprojectrestavratsija”, Moscow, 2009).
