The article contains the principal methodological points of the technology of geotechnical monitoring of engineer constructions in the cryolite zone. By way of practical example it was shown the efficiency of its application for reduction of risks in the industrial and economic activities of Gasprom Co by means of creation of numerical models of stability of ground basements and foundations, timely control of mechanical safety of buildings and constructions, qualitative substantiated numerical forecasting and potential variant modeling of aftereffects of technical decisions for stabilization of a situation. Geotechnical monitoring in contrast to the industrial production ecological monitoring is the technology for control of mechanical safety of buildings and constructions at the stages of their designing, construction and exploitation.
