When bedrock is deeper than known

1. Deeper penetrating pile lengths

2. Exceeding expected installation capacity of piling equipment

3. Overloading of caisson linings due to increased from earth

pressures

4. Increased ground water intrusion issues

5. Cost over-run

6. Completion time over-run
