Subject: Observation of Excavation, Proposed Event Center Shelter, Battlement Mesa Golf
Course, Battlement Mesa, Colorado
Gentlemen:
As requested, a representative of Kumar & Associates, Inc. observed the excavation at the
subject site on March 11, 2026 to evaluate the soils exposed for foundation support. The
findings of our observations and recommendations for the foundation design are presented in
this report. Chen & Associates previously conducted a subsoil study for design of foundations
at the clubhouse site and presented the findings in a report dated April 8, 1982, Job No. 23,751.
The current observation was performed in accordance with our agreement for professional
services with J. Martinez and Co. dated March 10, 2026.
The shelter foundation has been designed to be supported on spread footing pads placed on
the natural rocky soils and sized for the previously recommended allowable bearing pressure of
4,000 psf.
At the time of our visit to the site, the 16 footing pad excavations had each been cut in one level
from 1½ to 2½ feet below the adjacent ground surface. The soils exposed in the bottom of the
excavation were variable due to placement of road base in some areas and appeared to mainly
consist of silty clayey sand and gravel with cobbles. The results of a gradation analysis
performed on a sample of combined natural soils (minus 5-inch fraction) obtained from the site
are presented on Figure 1. No free water was encountered in the excavation, and the soils
were slightly moist to moist.
The rocky soils exposed in the excavation appear consistent with those previously encountered
on the site and can be used for support of spread footings designed for the recommended
