Subject: Observation of Excavation, Proposed Additions to Existing House, 0091
Meadowood Road, Lot 6, Block 2, Meadowood Subdivision. Glenwood Springs,
Colorado
Dear Kendra:
As requested, a representative of Kumar & Associates, Inc. observed the excavation at the
subject site on April 4, 2024 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 January 17, 2024, Project No. 23-7-640.
The proposed additions are located between the existing house and garage. Foundations were
designed as spread footings bearing on the natural soil and sized for an allowable soil bearing
pressure of 1,500 psf.
At the time of our visit to the site, the foundation excavation had been cut in 3 levels from 1 to
4 feet below the adjacent ground surface. The soils exposed in the bottom of the excavation
consisted of stiff sandy silty clay to clayey sand. Results of swell-consolidation testing
performed on a sample taken from the site, shown on Figure 1, indicate the soils have low
to moderate compressibility under conditions of loading and wetting. No free water was
encountered in the excavation and the soils were 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 limited 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
