A new method for assessing the physical wear of apartment buildings with defects included

Abstract

The article proposes a new method for assessing the physical deterioration of residential buildings, taking into account not only the physical deterioration of structures, but also the accumulated defects in buildings. The composition of operational wear, methods for their assessment and assessment of the real technical condition of structures and buildings as a whole are analyzed. At the same time, operational wear is considered as a combination of physical and moral wear. If physical depreciation is presented as a category of technical and economic, then the assessment of the degree of this depreciation is associated with the costs spent on its elimination. The technical condition of the building structure is also affected by defects accumulated at different stages (pre-project, design stage, prefabrication stage, storage and transportation of the structure, construction and installation and operation stage) of the existence of the building. The elimination of accumulated defects also requires corresponding costs. Therefore, in the article the accumulated defects are referred to as functional deficiencies and it is accepted as functional wear and tear. And the assessment of cumulative wear in determining the real technical condition, the inclusion of this wear is necessary. This article presents an algorithm and a mathematical model for accounting for this type of (functional) wear.
