NWAA Labs Construction Pictures

Construction started by trying to cut a hole in a "thin" wall. The cutting company came and estimated that a 10.5ft by 12.5 ft hole would only take a day or day and a half to cut. Little did they know that these thin walls were the walls of Troy! The marking and setup started and then we started cutting. At the end of two days we were able to only get a half of the hole completed. The cutter mentioned "A lot of steel" in this wall and showed me a cut block and I noticed that this wall had 3/4 inch rebar every six inches in both directions. He indicated this was much heavier than normal and would take a bit longer to cut because this wall had more steel than concrete in it!
