Geotechnical Site Investigation for Building Foundations in Permafrost Zones

Polar bear

Standard CAN/BNQ 2501-500
Geotechnical Site Investigation for Building Foundations in Permafrost Zones

Geotechnical site investigations are essential for the appropriate design, construction and maintenance of buildings. In permafrost zones, these investigations have an added level of complexity. This standard establishes a consistent methodology for performing geotechnical site investigations so that the results can be used to design building foundations with due consideration, in a risk management framework, of the conditions prevailing at the building site, including:

  • the distinctive characteristics of permafrost;
  • the seasonal and interannual climate conditions as well as the projected climate conditions over the service life of the building foundations.

In the long term, it is expected that the application of this standard will help lessen persistent maintenance issues, which, as a result of climate change or improper site evaluation, can cause permanent damage to structures.
