An analysis of work in the field of assessing the technical condition of building structures of industrial industrial buildings has shown that there are no uniform standards and criteria for assessing the technical condition of building structures of industrial buildings. There is no comprehensive approach to the issue of safety of industrial buildings that have completed their standard service life, taking into account the nature of changes in operating loads, degradation of the load-bearing capacity of the facility and the resulting risk of accidents. There is a need to develop uniform criteria for assessing the technical condition of building structures of industrial buildings, depending on the parameters of the identified damage (chip length, crack width, area of detachment of the protective layer of concrete, damaged reinforcement, etc.).The article presents an analysis of defects and damages in building structures of industrial buildings with reinforced concrete frames. Most methods for estimating the remaining life of buildings are based on the results of visual inspection of the technical condition of building structures and a subjective assessment by an expert. As a result of the analysis of defects and damage to industrial buildings, a method for assessing the technical condition is proposed based on the parameters of the identified damage (length, area, depth of damage).

Problems of service and repair of bridge constructions of a network of the irrigation canals which are on balance of managements of melioration are considered. The description and functionality of the automated imnformatsionny system developed by authors, allowing to carry out the account and monitoring of technical condition of bridge constructions in the territory of the Rostov region is provided.

Keywords: The meliorative channel, bridge construction, durability and operational reliability of bridge moving via water carrying out channels, monitoring of a condition of the bridge moving, the automated information system
