For
SI:
I inch = 25.4 mm, 1 kip = 1000 lbf = 4.448 kN, 1lbf-ft = 1.356 N-m.
1
Part numbers with “G” suffix indicate hot-dip galvanized coating. Part numbers without a “G” suffix indicate plain steel.
2
Shaft compression capacity (P2) is based on that the foundation system is fully braced as described in Section 4.1.3.
3
Helix capacity (P3) is applicable to both tension and compression loading and is based on a single helix plate with outer diameter of 8, 10, 12
or 14 inches (203, 254, 305 or 356 mm).
4
Shaft torsion rating is the maximum torsion that can be applied to the shaft during the helical pile installation.
5
Torque correlated soil capacity (P4) is applicable to both tension and compression loading and is based on torque correlation per Section
4.1.5, with piles installed at the maximum torsion rating.
6
For piles with extension(s), shaft coupling(s) must be installed in accordance with Sections 3.2.1 and 4.2.2 of this report.
