Subject observation of Excavation, Proposed Residence, Lot sD-5, Aspen Glen,
1014 Bald Eagle Way, Garfield County, Colorado
Gentlemen:
As requested, a representative of Kumar & Associates, Inc' observed the excavation at the
subject site on January 6,2025 to evaluate the soils exposed for foundation support' The
nndmg* 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 firraings in a report dated November 18,2024, Project No.24-7'208'05'
The proposed residence has been designed to be supported by spread footings placed on the
natural soils and sized for the recommended allowable bearing pressure of 1,000 psf'
At the time of our visit to the site, the foundation excavation was nearly complete and had been
cut in one level from about 2 to 3Yzfeet below the adjacent ground surface. The soils exposed
in the bottom of the excavation consisted of very stiff, blocky clay with calcareous traces and
scattered root holes. The soils disturbed at cut depth by the excavator had not been removed.
No free water was encountered in the excavation and the soils were slightly moist'
The clay soils exposed in the excavation are consistent with those previously encountered on
the site and can be used for support of spread footings designed for the recommended allowable
beari'g pressure of r,000 psf. our estimate is that around r to 2 feet of clay soil underlies the
excavation depth based on the previous exproratory pits dug a-t the site. The disturbed soils in
the footing areas ,hould be removed to expose the undisturbed natural soils' The bearing soils
should be protected from frost and concrete should not be placed on frozen 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
