How did the worker live and work through the winter while building summit tunnel

The worker was able to live and work in the tunnel because summit tunnels have lots of place and room for multiple things to fit in. It might not have been comfortable because most tunnels are dark and cold but it's very much so doable. Considering the worker was living in it the work part was very easy because the person could get up at any time and start working
