We uses Geostudio’s TEMP/W and SEEP/W programs to analyze the effects of engineering projects on subsurface thermal conditions. We have performed analyses for buildings, frozen core dams, roads, freeze-back piles, and injection wells in both arctic and subarctic environments and we can tailor our models to meet the needs of a wide variety of projects. Our studies have varied from simple models requiring only a few days to develop and study to highly complex coupled thermal/seepage models requiring many months of study and analysis. This type of analysis provides valuable insight into the thermal performance and environmental impact of engineering projects. Over time, the presence of structures changes the subsurface thermal regime which can damage infrastructure through differential settlements from thawing permafrost, frost heaving, and frost jacking. We can develop a model of any complexity to meet the needs of your project.
