Abstract: Calculation by force reveal of frosty bulging and force which keep bench mark, in condition of the peninsula Yamal was made. Construction of bench mark with level bench mark, with changing on height, has been offered It allows to lead the bench marks note to initial value and to exclude a repeated introduction of amendment in result on dimension. Creation of two system of heights on territory of gas field when in service has been offered. First system of heights intends for control of geometrical parameters of field constructions and equipment. Another system of heights intends for solutions and of scientific and applied tasks on studying of geodynamic processes at field.
