The article deals with the concept of material damage and losses in the study of construction and technical research, as well as the difference between the concept of losses in construction and technical and economic research.
The article proves that:
– in the study of construction and technical research, the concepts of damage and losses have identical meanings and are set as the cost of repairs;
– the use of the coefficient of physical wear is due to the fact that during the restoration work must take into account the previous state of structural elements, equipment and fulfill the principle of restoring the previous financial situation without receiving unjustified benefits, unjustified increase in property in losses;
– losses in the economic sense are considered as a broader concept than in the construction and technical, as they include not only the actual property losses, but also other legal losses that arose as a result of the actions of the entity and as a result of external events and actions of third parties, and therefore in determining the losses (damage) to the representatives of the judicial process must be clearly defined, especially in the economic process, exactly what losses (damage) should be established by the expertise;
– the computational approach of determining material damage (losses) for determining the repair depends on the initial data provided for the research of the expert in the study of construction and technical research.
Key words: material damage, losses, cost of restoration repairs.
