***OPEN HOLE***
The exposed materials at the base of the excavation for the basement foundation footings, beneath the north 7' of existing
footings, were observed. At an elevation of approximately 66.2', the exposed materials appeared to be comprised primarily of
coarse grained sands and gavels with scattered cobbles that were generally consistent with our experience of the anticipated
conditions in this area. A mini-excavator and shovels were used to expose the undisturbed native material in the foundation
excavations, and a vibratory plate tamper will be used to recompact the foundation subgrade surface prior to form placement. No
project geotechnical report has been prepared for this site, but plans call for an assumed allowable soil bearing pressure of 3,000
psf. Quantitatively verifying bearing capacity generally requires access to subsurface and Standard Penetration Test data.
Based on the limited amount of available subsurface data, the observed soils are deemed to be potentially capable of providing
an allowable bearing capacity of 3,000 psf, however, the possibility of the presence of weak subsurface materials resulting in
allowable bearing capacities less than 3,000 psf cannot be ruled out from surface observations only. In the event that
quantitative verification of allowable bearing capacity is necessary, drilling and sampling should be performed.
Justin with SRE Building Associates was immediately notified of today's observations.
