    Abstract. Monitoring is a continuous process of observations and registration of the object's parameters in comparison with the set criteria. The paper demonstrates the essence of monitoring of mechanical safety in new construction, reconstruction and exploitation of buildings and structures, including objects of historical heritage. The significance of monitoring is shown both as a means of control of preservation of urban development and as a preventive method, which provides timely identification and diagnostics of negative trends and allows taking adequate measures to normalize technical condition of a structure. There is a need to organize monitoring as an interactive process based on a computer model of soil-structure interaction. It allows to interpret adequately the monitoring results and to make back calculations to upgrade the initial calculation schemes and physical models of soils and materials. A conclusion is made that the monitoring can be an instrument for making new efficient structural and technological solutions. For this, on the basis of measurements under natural conditions, resources of bearing capacity of structures, a real field of stresses distribution can be determined and excessive reserves can be revealed.
    Key words: monitoring of mechanical safety of structures, construction, reconstruction and exploitation of buildings, geo-technical monitoring, interactive process.
