In an earlier post we saw the roof frame going up. Now we have a deck on Area 3. This image shows the corrugated roof decking.
You can see that the roof will be single pitched on these wings. On top of this will be water treatment, insulation, and a metal raised ridge surface.
A lone worker shooting "nails" into the steel. The slam and hammer of this powerful gun shoots rivet like nails through the metals anchoring the deck to the beams and girders.
All day long bang, BANG, BANG!!!!
