From my short stints in the construction industry (specializing in foundations)  in Siberia during college summers (“stroyotryad”) 30 years ago I don’t remember anything being done to the full specs and without cutting corners. Using full power of my imagination I still can’t picture somebody doing it 100ft there when 30ft would look the same :)</text><parent_chain></parent_chain></comment><story><title>Thawing permafrost is destroying Arctic cities (2016)</title><url>https://www.theguardian.com/cities/2016/oct/14/thawing-permafrost-destroying-arctic-cities-norilsk-russia</url></story>
