Correct bearing strata achieved, unless noted otherwise. 4) Initial Depth, Final Depth, and Top of Concrete Elevation, are relative to grade at time piers were drilled. Contractor must furnish actual elevation, if required. 5) Driller is hitting sand at approximately 10.5'. Per superintendent for Texas Unified, other piers were stopped at approximately 10'.
