Introduction Climate change and global warming lead to an increase in the average air temperature on the planet. This is most noticeable in the Arctic, which causes degradation of permafrost. This is reflected in the works by Epov M. et al. (2024) and Walter G.R. et al. (2011). The horizon of the cryolithozone boundary is decreasing in height every year. The problems of melting of permafrost soils in the Arctic zone are highlighted by Ngo Phan Thu et al. (2021). Changes in the mechanical properties of permafrost soils, on which the foundations of engineering and construction structures Abstract The article is devoted to the analysis of the values and gradient of vertical displacements of a group of construction structures that were built on permafrost soils in the Arctic zone of the Russian Federation. Due to the decrease of permafrost soil horizon and the development of cryolithozone thawing processes, many construction structures receive additional displacements in their foundation. These displacements are not designed, and they cause defects in load-bearing structures. One of the options for predicting and controlling the processes of development of non-design settlements of building structures is the organization of vertical displacement monitoring systems. This paper shows the values and gradients of settlements of a group of structures located on a thawing base. The possible magnitudes of additional settlements are analyzed. This is necessary in order to evaluate the possibility of using hydraulic leveling methods to control the elevation of buildings. © 2026 The Authors. Published by ELSEVIER B.V.
