JETTED PILES CAPACITY DETERMINATION DURING JETTING

[PT999]

How do you determine load capacity of jetted piles as they are jetted, as you would driven piles, with blow counts?

To the best of my knowledge, determining load capacity of a pile while it is being jetted is not possible. That is one reason why jetting is rarely allowed by pile driving specifications. However, in situations where jetting is practical, traditional pile driving may not be. Therefore either load testing of jetted pile (a few days after jetting is complete) or very conservative (jetted) pile loading may be reasonable.

A pile that is being jetted has no load capacity during the jetting operation...that is the purpose of jetting...to let the self-weight of the pile carry it to a predetermined jetting depth. After re-orientation or remolding around the pile, it may be load tested as SRE noted.
