8 days to get that wall up? How many guys? What concerns me most is that the entire backfill area is clean stone if I read right. I have had extensive discussions with my engineer about this very topic. Clean stone does not 'hold' grid, the way any materials with fines will. We NEVER backfill reinforced walls with all clean. We would put 12" of clean behind the wall and then fill the rest of the area with imported bank run. Yes it takes longer, but its a better install.
