Subject: Observation of Excavation, Proposed Residence, Lot 26, Block 2, Filing 1,
Battlement Creek Village, 19 Roan Creek Place, Garfield County, Colorado
Dear Torrey:
As requested, a representative of Kumar & Associates, Inc. observed the excavation at the
subject site on September 15, 2025 to 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 May 29, 2025, Project No. 25-7-245.
The proposed residence has been designed to be supported on spread footings placed on the
natural soils and sized for the recommended allowable bearing pressure of 1,500 psf.
At the time of our visit to the site, the foundation excavation had been cut in 1 level from 1 to 4
feet below the adjacent ground surface. The soils exposed in the bottom of the excavation
consisted of stiff, sandy silt with gravel. No free water was encountered in the excavation and the
soils were slightly moist.
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 and disturbed soils should be removed in the footing areas
to expose the undisturbed natural 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
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
(MOBC) developing in the future. If the client is concerned about MOBC, then a professional in
this special field of practice should be consulted.
