REMARKS:
1) Pier reinforcing verified to be correct in accordance with project plan
unless noted otherwise.
2) Concrete placed in piers within 8 hours of drilling completion, unless
3) Required Depth is based upon existing grade at time of geotechnical
bearing strata achieved, unless noted otherwise.
4) Initial Depth, Final Depth, and Topof Concrete Elevation, are relative
piers were drilled. Contractor must furnish actual elevation, if requin
5) A delay of approx. 90 minutes between the drilling of the' straight sba
belling (under-reaming) was due to a broken reamer.
6) Pier C/3, initial depth was 19.0'. Due to more than 12" of water in I
