HiZane,
I visited the site on Aprit 16,2024 to observe the exposed soil.s in the foundation excavation for
suitabitity of foundation support. The foundation excavation was cut in one [eve[, 3 feet below the
adjacent ground surface. The soits exposed in the bottom of the excavation consisted of stiff,
moist, very sitty sand. The soit conditions exposed in the excavation are consistent with those
previousLy encountered on the site and suitabte for support of spread footings designed for the
recommended al.towabte bearing pressure of 1,500 psf. There coutd be some post-construction
setttement (and differentiat to the existing buitding), especiatty if the bearing soits become wetted
Loose and disturbed soits in the footing areas should be compacted prior to placement of
concrete. ln the stab area, existing fitt was observed above the existing watervatves and water
lines. This material. shoutd be removed from beneath s]ab areas and reptaced with structural fill
compacted to at teast 95 percent of the standard Proctor density at a moisture content near
optimum, or a structural slab used to bridge the existing fitl, material to reduce slab setttement
potential.. lwil,L send you the letter as soon as the Lab testing is complete.
Thank you,
