COHESION VALUE ON STANDARD PENETRATION TEST DATA

[neukcm]

Hi,

I just want to get your advice, is it safe to use the value of COHESION determined in SPT BORELOG Report?

Please see attached file. I'm currently designing pile foundation, 9m deep. I'm using spreadsheet that utilizes cohesion to obtain the pile resistance in shaft and base.The value of cohesion, bulk density, Atterberg limits etc is given only under 12m deep but my pile penetration is only 9m. Can someone share some insights on this. Please take a look at the soil report.

Thanks,
neukcm
