Dear Mr. Howard,
As requested, a Geotechnical Engineering Group (GEG) representative
performed observation and testing services on a full time basis during
construction of the structure foundations listed above by Garfield County Building
Permit No. The GEG representative tested structural fill compaction beneath
foundations, tested concrete properties, observed reinforcing steel placement
and documented structure to foundation anchorage for each of the structures.
The purpose of this letter is to present our review of observation and testing data
and our conclusions regarding final foundation construction of the subject
structures. In summary, each of the structures identified was constructed in
conformance with the referenced engineering design documents.
Following is a summary of the GarCo Permit No., Design Identification and
the structure common name for each structure reviewed:

Conclusions
Review of our records indicates proper structural fill compaction beneath
foundations, proper concrete strength, proper reinforcing steel placement and
proper structure to foundation anchorage for each of the structures. Based on
this review, we conclude each of the structures identified was constructed in
conformance with the referenced engineering design documents.
We appreciate the opportunity to perform engineering services. If we can be of
further service or answer any questions regarding this letter, please call.
