Aim of this work – to set forth general principles of ground of efficiency of informatively-measuring technologies in the process of exploitation of objects of the real estate. Methodology. The method of substantiating the effectiveness of the restoration of the technical condition of real estate in the process of their operation is based on the use of information and measurement technologies to establish the technical condition of the object, which is a combination of information retrieval methods, instrumental measurement, analysis and processing of such information, technological and technical solutions to ensure the operational suitability of the facility in conditions of uncertainty. The method involves the formation of a repair strategy using information and measurement technologies based on the development of the life cycle of repairs and algorithms for selecting options for instrumental monitoring systems, choosing the procedure for studying the duration of measurement work, justification of labor and information technology costs and comparative assessment of total costs of real estate object. Results. It is established that measuring works are an integral part of the process of operation and repair work in its composition, which are carried out according to a single schedule of operation of the building and are part of repair work, and the frequency and volume of measuring, including geodetic work correlate with. To plan the volume of measuring work, their duration and labor costs are determined on the basis of existing time norms, and in their absence – by methods of technical rationing. Substantiation of the effectiveness of information and measurement technologies in the operation of real estate is performed by comparative assessment of total costs during the operational stage of its life cycle, taking into account the costs of implementing information and measurement technologies, that is the set of processes for obtaining information by instrumental measurement and processing ‘effective conclusion on the technical condition of the property. The scientific novelty of the obtained results is in the development of general principles for substantiating the effectiveness of information and measurement technologies in the operation of real estate. The practical significance lies in the improvement of standard solutions for the choice of composition and content of information and measurement technologies, taking into account their impact on the duration and labor costs of all types of repairs and reconstruction.
Introduction. Forecasting the dynamics of the progressing of building deformations with the use of the data of instrumental measurements should take into account the influence of geodynamic processes and other factors of the external environment on the operational suitability of buildings. The duration of the life cycle of buildings depends on the timely consideration of the damage threats and forecasting of changes in their technical condition under the influence of natural, man-caused, constructional, and operational factors.Problem Statement. Untimely detection and elimination of defects is the cause of damage and deformation of buildings.Purpose. The purpose of this research is to forecast the progressing defects and damage by the methods of timely assessment of the technical condition of buildings, with the use of instrumental measurement data on the influence of environmental factors on the mechanism of destruction and wear of buildings during their construction and operation.Material and Methods. The methods of analysis and generalization have been used to substantiate the relevance and to formulate the purpose and objectives of the research. The retrospective method for studying the objects over time has been used to collect statistical information and analytical materials on the main parameters of their construction and operation. To forecast the parameters of instrumental measurements at the stages of the life cycle, there have been employed the following empirical research methods: survey, monitoring, generalization of experience, expert surveys, expert evaluations, and forecasting. Risks of damage have been assessed based on the materials of engineering studies, given the possibility of hazard activation, the power and remoteness of the threat source, the technical condition of buildings, and the compaction. The initial data for choosing an effective system are: the stability of the slopes where the building is located, their steepness, the condition and geological composition of the soil base, sources of possible flooding and vibrations. Results. The authors have proposed choosing an effective system of instrumental observation of landslides during the construction and operation of buildings given the vulnerability criterion. The developed method allows choosing an effective system of landslide observations, during the construction and operation of buildings, given the mentioned criterion, i.e. the property of the building to lose serviceability as a result of its possible damage under the influence of negative factors.Conclusions. The proposed method can be used to determine the scope of instrumental observations of landslides and the periodicity of landslide control during the construction in complex geodynamic conditions.
