Brad sent me an email today saying they took some core samples from the walls. It tested to 2,910 lbs which is great. I suspect the reason they took samples from the walls is because the day-14 sample that was cast when they poured the walls, did not test very well.

Brad is going to move forward with the waterproofing of the walls and will pour the backfill on Friday.

Correction and update on 9/14/2006:
Brad told me today that the core samples were tested at 2,560 and 2,610 lbs by Granite Rock. The reason why core samples were taken was because the day-14 sample tested to only 1,710 lbs by DCI. Brad said he wants to test the remaining two cast samples at DCI to verify the results obtained by Granite Rock.
