How is the soil density obtained during the test
As contractors, we do not endorse any particular method to derive soil density (or other parameters), but you can find some commonly used formulas in Professor Paul W. Mayne's works. Another option would be to use DMT readings as an additional line of evidence complementing the Vs measurements.
Can't the calculation of the Vp wave be done using the true interval method?
Hi Sergio, I will ask Jonas to respond to you. He doesn't get the notifications here.
@@LegionDrillingAustralia Hi, you got an answer ? Thanks
@@fourfunkybass Sorry I missed this one. Using the true interval method for Vp is challenging due to the high velocity of p-waves, but it isn't unfeasible. This option is not implemented in the current version of SDMTPro, but hopefully we will see it incorporated in the future. Thanks, Jonas

Is this environmental work or like phase 1’s?
It's exploration for coal, oil and gas. Poofters need not apply.
