Thanks so much to everyone. I really appreciate this.
Our final submittal was before my post, so we wouldn't have a chance to ask the question to the geotechnical engineer. However, we did use their values subtracted by water unit weight since they are more conservative.
Next time I'll make...
I normally see an effective unit weight of sandy soil below water table in range of 45 to 65 pcf for input of LPILE, GROUP, or COM624P. My understanding is that effective unit weight is basically a saturated unit weight minus water unit weight (i.e. submerged unit weight).
However, the...
