Effects on Skin Friction
- Skin friction dominated capacity
- Defects appear to have a small effect on capacity, but further research is needed.
- Reloading resulted in 30% reduction in capacity, possibly due to (1) Breakage of Cementation (2) Remolding of Clay, or (3) Structural Defects.

Effects on End Bearing
- Soft bottom resulted in 33% reduction in capacity relative to undisturbed soil
- Reloading resulted in 20% reduction in capacity relative to undisturbed soil

Although undocumented differences in construction may have affected the results, the data suggests:
Load Test — Shaft 2
Load Test — Shaft 4
Load Test — Shaft 4-Reload
