hole in a brick wall

This is outside a substation near stanley county, North Carolina, where we are core drilling a 4 inch core drill hole with one of our own core drill bits and it went perfectly. The rig had to mounted upside down to be able to get center of where the penetration of the 13 inch reinforced brick wall need to be for the grey electric pipes to be able to pass through to make it to the control boards located inside the building.
