As requested, a representative of Kumar & Associates, Inc' observed the excavation at the
subj ect site on August I 5 , 2;24toi evaluate the soils exposed for foundation support' The
findings of our obsetvations and rpcommendations for the foundation design are presented in
this report. We previously conduOted a subsoil study for design of foundations at the site and
presented our findings in a report pated septemb et 7,2022,Project No' 22'7424'

excavation are consistent with those previously encountered
of spread footings designed for the recommended allowable
observed.
The addition will be along the baqkside ofthe residence and supported by spread footings
sized for the recommended allowdble bearing pressure of2,500 Psf'
At the time of our visit to the site,the foundation excavation had been cut in one level from
about 3 deeP next to the to about 12 feetdeep at the uphill side where a soil nail wall
had been installed to suPPort the face. The cut depth exposed the footings of the
residence. The soils exPosed in bottom of the excavation consisted of relatively dense, silty
water had been encountered in the excavation bottom and
bearingpressure of 2,500 Psf.and disturbed soils should be removed in the footing areas
s. The water seepage into the excavation should continueto expose the undisturbed natural

removed before concrete Other recommendations presented in our previous report
this letter are based on our observation of the soils exposed
the previous subsurface exploration at the site. Vmiations
in the subzurface conditions the excavation could increase the risk of foundation
of any variations encountered in the excavation conditionsmovement. We should be
for possible changes to the contained in this letter. Our services do not include
