CAN/BNQ 2501-500/2025

The standard CAN/BNQ 2501-500 proposes a consistent and robust methodology for carrying out geotechnical site investigations in a risk management approach adapted to a changing climate. This methodology is based on a detailed assessment of the site-specific conditions and on rigorous reporting of results. It takes into account current and projected climatic conditions to ensure the resilience and sustainability of infrastructures to face the impacts of climate change. Geotechnical site investigations are crucial for adapting buildings and structures to climatic conditions, particularly in permafrost zones, where complexity is heightened. With the accelerated warming of the Arctic, these engineering challenges become even more pressing. An appropriate geotechnical site investigation program allows to select the proper foundations for a given site, whether for new construction or the rehabilitation of existing structures.
