Dear SUSheikh,

Main reasons where Hiley's Formula cannot be applied are:
1. Improperly using hammer weight compared with the pile weight.
2. Design pile end bearing capacity is beyond this formula.

Any how, could you please post your screen shot? Which part you said It doesn't work?
If you understood the principle of formula, you should known why it doesn't work. My file can be edited, it doesn't be locked, you can look into them and make understanding it.

Did you compare with hand calculation?
Don't use any software without basic background of it !!!!!!!

Regards.
