Foundation Repair of Western Colorado
2575 Highway 6 & 50
Grand Junction, CO 81501
DL Engineering Inc. reviewed the progress of construction from photos provided by the contractor for
the subject project on May 20, 2022. The following is a summary of the observations made:
NEW OBSERVATIONS :
PUSH PIERS
• Reviewed the (15) push piers. For push piers 3, 13-15 on the as built plans a ½” flat steel
plate was installed as face-mounted brackets, this was approved by the engineer on
record. Below is a table summarizing pier locations:
Pier Quantity Wall Location (N/S/E/W) Pier Spacing (on center)
8 W Per As Built Plans
7 N Per As Built Plans
• The pier spacing was observed and appears to be in conformance with the
construction documents.
• The piers were installed to refusal or to a depth no less than that specified in the
construction documents.
• The push piers appear to be installed in conformance with the structural
mitigation plan.
VOLATILE SOILS:
The moisture around the foundation elements must be controlled for the useful life of the building. Time
has shown that Colorado soils can be unstable, and structures can experience damaging movements due
to expanding and shrinking soils, primarily when moisture changes occur. Maintaining consistent soil
moisture contents around all foundation elements is crucial to minimizing foundation movements. Even
with properly engineered/constructed foundation systems these volatile soils can still exert excessive
pressures causing damage in the residence. If the Owner would like further insight about the on-site soil
conditions and preventative measures, a Geotechnical Engineer should be consulted.

GEOTECHNICAL CONSIDERATION:
It is possible that the piers may consolidate the soil under the piers. Because of this, periodic surveys of
the supported structures should be conducted to assure project success. The Owner should be responsible
for annual surveys certifying project success. It is recommended that a baseline survey be conducted
immediately. The Owner should report all findings and reports to the Structural Engineer. If vertical
movement of the foundation walls is discovered, the piers should be re-pressurized. A Geotechnical
Engineer should be present for the re-pressurizing of the piers.
DISCLAIMER
In as much as the site review of an existing structure for the purpose of observing the structure conditions
requires that certain assumptions be made regarding existing conditions and because some of these
assumptions may not be verifiable without expending additional sums of money or destroying otherwise
adequate or serviceable portions of the building, the Client agrees that, except for negligence on the part
of the Engineer, the Client will hold harmless, indemnify and defend Engineer from and against any and
all claims arising out of the professional services we have provided.
