THE FOLLOWING WAS NOTED:
Helical Piles:
AESI was onsite today at 10am, as requested by the contractor to observe and document installation of helical piles.
The contractor set up and installed helical pile H1 to a depth of 20 feet below the bottom of the foundation where the
torque pressure met 1,700 psi. The helical pile appeared to be installed to minimum specifications, per plan. Afterwards,
the contractor began installing two helical on either side of pile H10 that will serve as reaction piles for the load test planned
for Monday (11/28).

NOTES:
1. CONTRACTOR SHALL VERIFY HELIX CONFIGURATION CAPABLE OF DEVELOPING THE DESIGN LOADS.
2. MIN INSTALLTORQUE ASSUMES Kt= 9.0IF A PILE WITH A DIFFERENT Kt VALUE IS USED MIN INSTALL TORQUE SHALL BE ADJUSTED.
3. MIN INSTALL TORQUE INCLUDES A FACTOR OF SAFETY OF 2.0.
4. ALL PILES SHALL INSTALLED TO TWICE THE DESIGN LOAD.
