The purpose of this article is to select and substantiate the criteria for protective construction monitoring of main pipelines. Main pipelines are constantly exposed to influences of external and internal factors. Special protective constructions are being raised to ensure the continuous operation of the pipelines. The main goal of creating protective constructions is to minimize economic losses and preserve the environmental characteristics of the facility. All existing protective constructions can be divided into two large groups: earth work and engineering constructions. Each of these groups includes different types of the constructions. All of them are designed to ensure safety of main pipelines from a certain natural phenomenon. It is also necessary to ensure constant monitoring of their geometric state regardless the protective construction type. Various data can be used for monitoring, among which the Earth remote sensing data perform a special role. One of the main issues in the construction monitoring is the explanation of the arising measurement errors. This requires knowledge of complex precision calculations theory. It is also necessary to take into account that a visual inspection of the construction defects is imperative in any calculations. A classification of protective constructions is given. The base of the accuracy calculation theory that is necessary to substantiate the errors in the protective construction monitoring is discussed. The main accuracy standards based on this theory are highlighted. The results of the performed analysis are the numerical values of the accuracy criteria for various protective construction types.
