Plan de conservación y mantenimiento preventivo de las ornamentaciones de las fachadas de las casas del centro histórico de Cuenca de los siglos XIX-XX

Abstract

The vulnerability to threats of anthropic origin of dissociation for the occurrence of risk in the ornamentation of the façades of the houses of the first order area of the city of Cuenca constitutes the problem addressed by the study. The methodology was based on the current situation of the ornamentation, then the patrimonial and risk assessment were designed and applied technical data sheets for relevant information demanded by the letter of Nara for the equity valuation and the risk management methodology of a stratified sampling, and the field information was collected with 120 tokens collected through interviews. The equity valuation begins with the process of identifying patrimonial values through the Matrix of Nara, supporting us in the bibliographic or secondary documentation and primary information of the records. Once the patrimonial values of the ornaments were identified, with the patrimonial valuation method we proceeded to estimate the level of expression through a statistical analysis of regression and correlation of the parameters that constitute these are the expression or material authenticity, the authenticity of the space and the form and integrity that together constitute the level of expression, unit of measure of the equity value. Subsequently, with information on the risk management sheets, the risk assessment method was applied based on the criteria of the ISO 31000: 2009 methodology of the International Organization for Standardization for Risk Management of Cultural Heritage Properties and adapted for the management risk of ornamentation was used for the estimation of the magnitude of risk. Once the level of expression and the magnitude of risk were obtained, the method of priority of results was applied which determines and suggests the measures and actions necessary for the state of danger of the ornaments. The estimation of the magnitude of risk is summed up with the estimation result of the magnitude of risk and collated with the scale of weighting of results for the interpretation of quantitative qualification of the results of the sum of the magnitude of risk and level of expression that was of 21.3, that for this classification the weighting scale suggests measures and monitoring actions, more studies for corrective and emergent actions, guiding to construct the treatment of risks, structured mainly according to the 5 stages of risk control suggested by the method applied, these steps focus on avoiding, blocking, detecting, responding and recovering, which underpinned the guidelines for the formulation of the value-based preventive conservation plan.
