(NIA-KRASNOYARSK) - The work of the monitoring center for buildings and structures, which permits to quickly monitor the condition of foundations and foundation soils, was presented at the panel discussion "Digital Cluster of the Construction Industry in the Siberian Region" held at the Krasnoyarsk Economic Forum (KEF).

The center is operating within the Polar Division of Norilsk Nickel. Thanks to the information and diagnostic system, all processes of geotechnical monitoring are automated, and data on the state of objects located on permafrost are monitored in real time.

“We use three types of sensors: a temperature sensor that is installed in the subgrade and reacts in case of thaw; inclinometer - a sensor that allows you to determine the spatial position of foundation structures; an air temperature and humidity sensor that informs about the leakage in piplines,” said Anton Pryamitsky, Deputy Chief Engineer of the Polar Division of Norilsk Nickel.

The data obtained make it possible to detect and prevent in advance the deformation of buildings and structures, which occurs due to global warming and the associated thawing of soils.

According to Anton Pryamitsky, first of all, the monitoring system included oil refining and oil storage facilities, administrative buildings and a number of industrial facilities as a “pilot” project. The second stage of the project will include another 53 facilities of the Norilsk-Taimyr Energy Company, then all tailings of the Norilsk division will be equipped with sensors. In addition, the issue of introducing monitoring at extended facilities - pipelines and gas pipelines, power lines is currently being worked out.

“We also planned to develop a climate model for the areas where the company operates. In addition, we are actively investing in background monitoring and have already drilled wells in order to study permafrost together with scientists from the Siberian Federal University and Polar State University. All these data will become the basis for creating a calculation model that will allow us not to assign criteria at once, but to analyze and calculate in advance what will happen to the soils and, accordingly, the buildings located on these soils in the future,” said Anton Pryamitsky.

In addition, thanks to the work of the monitoring system, to date, nine buildings in the Norilsk industrial region have begun major repairs, which will strengthen the existing foundations and prevent damage.
