In the work on the basis of analytical analysis of tabular data, both current and previous domestic regulatory documents on civil engineering, for mechanical indicators of bonded soils of natural occurrence graphic and analytical (formula) interpretation of these values in relation to the values of the dynamic probing index of Pd, MPa, and yield index IL, units, for the degree of water saturation of these soils Sr ≥ 0.8 units is given. Correlation with the value of dynamic probing of Pd, MPa allows not only to differentiate engineering and geological (geotechnical) cross-sections, more or less detailed, but also to estimate the load-bearing capacity of selected layers of bonded soils accurately enough. The theoretical analysis has shown that the values of mechanical indicators of natural bonded soils adopted in the current regulatory documents, even taking into account their structural strength, can not be directly used as a prototype to assess similar indicators of compacted technogenic soils of artificial structures in the form of embankments of hydraulic dams, road embankments or airfields. This is due to the fact that in the vast majority of cases in civil construction assessed the properties of soils in the plastic state, which tend to have a lower density of dry soil than at the border of rolling, and a mandatory condition for the use of such soils in artificial soil structures is their compliance with the requirements of the so-called standard compaction, that is, the density of dry soil there should be more than the density of dry soil at the border of rolling. These soils are in a solid state (their concentration is ≥ 85 %) and indeed (through direct contact between the soil parts) work as an elastic body and can be characterized by a modulus of elasticity with a corresponding small elastic deflection lmax and a sufficiently large design critical resistance value of R0 ≥ 0.6 MPa, which must be determined at each laboratory test of the samples before they fracture or disproportional movement of the stamp.

The paper investigates environmental risk factors that determine the value of real estate assets and make valuation decisions. It is determined that the components of the environment are the object of the cumulative impact of environmental risk, and indirectly through them are real estate objects and people. Among all the environmental components, the most decisive is the atmosphere, as the harmful substances coming from the atmospheric air into the human body are absorbed most intensely. The main criterion for environmental risk assessment is the degree of influence of harmful substances on the health of the population. The systematization of environmental risk factors, which provides an analysis of the causes, sources and significance of negative material and physical impact in the study area with the separation of two qualitatively different types of environmental risk: direct and indirect. Both positive and negative environmental factors that affect the value of real estate are listed. It is proposed to determine environmental risk as part of a probabilistic approach to assess the deterioration of life due to the deterministic and stochastic effects of environmental pollution surrounding a real estate object. Dependencies for quantitative estimation of direct and indirect environmental risks are determined. Conceptual bases for objective consideration of negative environmental factors of material and physical nature in the developed territories have been developed.
