DETERMINATION OF THE PRIORITY OF RESTORATION OF TRANSPORTATION INFRASTRUCTURE OBJECTS TAKING INTO ACCOUNT EXPERT ASSESSMENT

Abstract

The paper proposes an approach to determining the expert assessment of the bridge as a whole, taking into account the defects that arose as a result of operation and as a result of circumstances unforeseen by the project (military actions), which led to the transition of the structure to the 5th operational state. In contrast to the methodology given in the current regulatory documents, the authors propose to supplement the procedure for determining expert evaluation, in terms of reducing ΔE points, taking into account the degree of destruction of building elements and changing the range of expert evaluation points. This will make it possible to assess the impact of the share of damaged elements, effectively determine the overall degree of destruction of the structure and provide an opportunity to make informed decisions about the nature, sequence and priority of carrying out repair and restoration works or the need to build a new structure. Bridge restoration planning should be based on an understanding of the economic capabilities of our country. Thanks to the proposed approach, it is possible to more effectively plan restoration works depending on the degree of destruction of the structure, giving economic meaning to the impact coefficients, which will allow rational use of funds.
