Gentlemen:
Edward M. Morris, P.E. of Grand Junction Lincoln DeVore, examined the open excavation on this site on 4-
19-2024 (upper level) and 4-23-3034 (lower level). In -place soil density testing of the reworked subgrade
soils was performed. The 4 in -place soil densities were found to range from 105 to 109 pounds per cubic foot.
These soils were found to be very similar to those soils described in the Report of Subsurface Soil Exploration
performed for this site by Grand Junction Lincoln DeVore, Job # 95824gj, dated March 27, 2024. The
reworked subgrade soils were judged to be capable of supporting the structural fill. It was determined that
a geotextile fabric for either separation or reinforcement was not required.
Edward M. Morris, P.E. of Grand Junction Lincoln DeVore, observed the recently placed structural fill on
the above -referenced site on 4-23-2024 (upper level) and 4-25-2024 (lower level). The structural fill was
found to consist of approximately 14" (upper level) and 16" to 30" (lower Level). In -place soil density tests
taken on the structural fill indicated that compaction was either equal to or in excess of 90% of the modified
proctor density (ASTM D-1557) for these materials. The structural fill appears to meet the minimum
recommendations in the Report of Subsurface Soil Exploration performed by Grand Junction Lincoln DeVore
and the foundation design prepared by Grand Junction Lincoln DeVore.
We hope this letter has provided you with the information required. If questions arise, or if further information
is needed, please feel free to contact Grand Junction Lincoln DeVore at any time.
Respectfully submitted,
