Construction of the New Narodni Trida Metro Station, Picture 4, Prague, CZ, 2013

This is one of the floors of the new station over street level, again with very heavy-duty concrete construction, or at least, I hope it's heavy duty as opposed to just heavy. Although the building has a heavy steel frame around the outer wall (or what will be the outer wall), the supports for the floors aren't visible in this shot, as those beams you see are part of the scaffolding (right?).
