Ensuring accuracy of prolozheniya of the levelling courses at research and carrying out of elevation marks of pickets at construction of highways

Ensuring accuracy of a prolozheniye of the leveling courses at research and carrying out of elevation marks of pickets at construction of highways is considered. Admissions, classes of leveling and length of the high-rise courses at their prolozheniye are provided lengthways or on the route at research and carrying out of elevation marks of pickets at construction of highways taking into account their categories, uses of sets of cars of keeping of elevation marks and coefficients of accuracy of technological processes when performing geodetic and construction works.
