It is generally accepted that the accuracy of the geometric characteristics of structural elements is one of the key indicators of construction features. GOST 21778-81 states that the necessary means and principles of technological accuracy are used in the production of the design of structures. The accuracy of building elements according to geometric characteristics depends on inaccuracies in the manufacture of parts, geodetic alignment and construction works. From this it follows that the indicators for the accuracy of geometric characteristics and the reliability of building systems for the purpose are interconnected. The reliability factors of building systems for the intended purpose depend on the level of responsibility of buildings and structures. Therefore, the purpose of our work is to justify the purpose of the accuracy of geodetic works in the construction of steel tanks, taking into account the level of their responsibility. Conducting research by many authors indicate that the distribution of errors in the sizes and positions of the structure of components is subject to the normal distribution law. It is proved that elementary errors in the position of the order of components and nodes are summed up. The value of the reliability factors for the accuracy of the geometric parameters of the building structures of steel tanks is not yet sufficiently substantiated. Tolerances for geometric parameters in the construction of steel tanks are proposed to be assigned taking into account the indicators of their reliability in terms of responsibility. The substantiation of the accuracy standards (mean square deviations) for the geodetic support of the construction of steel tanks was carried out taking into account the class of construction and reliability indicators of their building structures in terms of responsibility.
