R Calcs and source checks

Current workspace kernels were executed headlessly. A separate original adapter reproduces the engineer’s foundation arithmetic. The new adapter has not been installed as a native client module.

Geotechnical basis conflict

The March 2011 distress-repair report states 500 psf skin and 2,000 psf tip resistance; the September 2026 calculation uses 500 and 3,000. Neither comparison determines current applicability. At the stated 30-inch diameter and eight-foot embedment, source scenarios give about 41 kip versus 46 kip allowable. P6 demand is about 30% versus 27%. The responsible engineer must establish the applicable current basis.
