Pile sizing has been done following the applicable project location standards based on a project given loading and the following points:

a- Pile mechanical resistance including connections and brackets

b- Pile soil resistance based on well-known industry standards and  principles

c- Geotechnical report and soil parameters

​

Helical (screw) piles are designed to carry axial and/or lateral and/or moment loads. Pile installation is done following the guidelines set out in the GoliathTech installation manual and performed by certified installers. Pile installation verification is done using one or both of the following: 

a- Empirical well-known/tested installation torque to capacity ratio using the following equation

P=Kt x T

Where:

P = Pile Installation Capacity
T =  Installation average torque last 3ft
Kt = Empirical factor based on the pile size/diameter

b- Pile standard compression and tension test:

Compression ASTM D-1143-07 and/or ASTM D3689-07 
Tension ASTM D3689-09
