Project No. 21-7-231
Subject:Observation of Excavationo Proposed Residence, Lot27, Callicotte Ranch,
Callicotte Ranch Drive, Garfield County, Colorado
Dear Edgar:
As requested, the undersigned representative of Kumar & Associates, Inc. observed the
excavation at the subject site on August 27,2021 to evaluate the soils exposed for foundation
support. The findings of our observatíons and recommendations for the foundation design are
presented in this report. lVe previously conduoted a subsoil study for design of foundations at
the site and presented our findings in areport dated March 26,2AZl, ProjectNo. 2l-7-231.
At the time of our visit to the site, the foundation excavation had been cut in one level from I to
5 feet below the adjacent ground surface. The soils exposed in the bottom of the excavation
consisted of basalt gravel and cobbles in a white sandy silt matrix. No free water was
encor¡ntered in the excavation and the soils were slightly moist to moist. Up to about 1 foot of
on-site sandy silt soils was being placed as fill on the westem side of the excavation. The fill
should be moistened and well-compacted.
The soil conditions exposed in the excavation are consistent with those previously encountered
on the site and suitable for support of spread footings designed for the recoilrmended allowable
bearing pressure of 2,000 psf. Loose and disturbed soils should be moistened and compacted or
removed in the footing areas to expose the undisturbed natwal soils. Other recommendations
presented in our previous report which are applicable should also be observed.

The recommendations submitted in this letter are based on our observation of the soils exposed
within the foundation excavation and the previous subsurface exploration at the site. Variations
in the subsurface conditions below the excavation could increase the risk of foundation
movsment. We should be advised of any variations e,ncountered in the excavation conditions for
possible changes to recommendations contained in this letter. Our services do not include
determining the presence, prevention or possibility of mold or other biological contaminants
(MOBC) developing in the frrture. If the client is concerned about MOBC, then aprofessional in
this special field of practice should be consulted.
If you have any questions orneed further assistancg please call our office.
