L0k,
The hammer was a Junttan HHK-9A hydraulic hammer so there isn't a fall height. The rig provides an estimated energy level for each blow. But in case you were wondering the HHK-9A has a ram weight of 19.84 kips, max stroke of 4 feet, and a max rated energy of 79.36 ft-kips.
The hammer was running around 51 ft-kips for the HP14x89 and 44 ft-kips for the HP12x74 (based on the PDA test results). I've noticed that the estimated energy on the rig doesn't always match the PDA, especially if the pile driving contractor does not input the correct hammer specs into the computer.
For the static load tests, the piles failed around 1.5 to 2-inches of displacement. Pile set was around 0.4". Not sure what rebound is but I'm guessing it's displacement at failure minus pile set?
Also just, an FYI, the final blows were blows/inch.
