The construction site was located in the middle of the taiga, surrounded by lakes and rivers. Winter temperatures dropped below -30 degrees Celsius. Workers lived in dugouts, tents, barracks, and barns. They had no access to regular supplies of food, hygiene, or medical supplies. In addition, the equipment at their disposal constantly broke down, and horse-drawn carriages were used to haul away debris.
Work took place 24 hours a day, regardless of the prevailing weather conditions.
