Estimation of Allowable Bearing Capacity of Basement Rock

We have a location where a Standard Penetration Test (SPT) has been done up to 22m below the ground level, and additional 8m coring in weathered rock, with "ZERO" Rock Quality Designation (RQD) values, when the Client ordered termination of boring.

How can we estimate the allowable bearing capacity of this rock? Is carrying out Uniaxial Compressive Strength (UCS) test, the only possible method?

Many thanks in advance.
