The actual cost was relatively cheap to get to the bottom , 1 Million for the concrete piles , 200,000 for the grouting of the bottom and sides and about a 1 million for excavation ( we also had to blast through some limestone in the center) we also had to excavate another 120 feet horizontally once we reached the bottom to tie into a sewer tunnel. It took about 4 months to do start to finish . ... I don't know what the OI boys spent per hole over the last 2 years .. but a little over 2 million for a big , safe, dry hole is pretty darn cheapThat would be good way to get a 33' diameter hole excavated there. It seems they don't have too much extra money budgeted beyond what was spent this year. What would be the ratio of the additional cost to do a big dig like this compared to the 3 they sunk this year - X10 , X100, or X1000?
