Prognostication of relations between the buildings age and deterioration of construction

The untimely reconstruction of the building can lead to its liquidation, despite the intrinsic value. Such measures can be prevented if a competent program for organizing reconstruction is present. To create an organizational and technological model of reconstruction, it is necessary to know the parametric dependencies of the characteristics of the studied buildings. To analyze the data on the conditions of existing houses, a mathematical model is used, built in the 3d table curve software. 55 houses were selected, 11 buildings in 5 districts of St. Petersburg. Using of the equations obtained, it is possible to predict the deterioration of structural elements in the future using the described method. The most important thing is the organization of timely actions on the basis of projected data: planned repair and reconstruction
