Subject: Observation of Excavation, Proposed Residence, Lot 16, Spring Ridge Reserve,
125 HighPoint Drive, Garfield County, Colorado
Trevor:
As requested, a representative of Kumar & Associates, Inc. observed the excavation at the
subject site on May 3, 2021to evaluate the soils exposed for foundation support. The findings of
our observations and recommendations for the foundation design are presented in this report.
'We previously conducted a subsoil study for design of foundations at the site and presented our
findings in a report dated January 8,2027, Project No. 20-7-759.
Spread footings placed on the natural soils and sized for the recommended allowable bearing
pressure of 1,500 psf were designed for the foundation support.
At the time of our visit to the site, the foundation excavation had been cut in one level from
3%to 6 feet below the adjacent ground surface. The soils exposed in the bottom of the
excavation consisted of stift slightly calcareous silty sandy clay. No free water was encountered
in the excavation and the soils were moist to very moist from the recent rainfall.
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 recommended allowable
bearing pressure of 1,500 psf. Loose disturbed soils in the footing areas should be moisture
adjusted to near optimum and compacted before placing footing forms. 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
movement. We should be advised of any variations encountered 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
