When all preparations for basement are finished and ready for mounting of the dome, the work is quite easy to make by the first two sections mounted to each other.
This continues all the way round by mounting iron bolts through predrilled holes, even not with a final tightening. Pentagon windows and walls are put in place, and followed by 5 roof- hexagon sections.
The final top is the pentagon. When all sections are adjusted the iron bolts can be tightened.
