Re: Open.hole inspection and fill Compaction Testing/Evaluation Report, 1054 River Bend
Way, Glenwood Springs, CO
American GeoServices, LLC (AGS) have performed field evaluation/inspections at the referenced
site to evaluate/inspect the excavated subgrades for the proposed residential construction. We
noted soil conditions at the excavated footing subgrade levels, the site conditions matching the
descriptions provided in the original geotechnical report. Based on our field inspections, we
recommended over-excavation of 2feet and backfilling with non-expansive structural fill in the
footing areas along with the placement of a geogrid in accordance with the recommendations
given in the original geotechnical report.
Subsequently, we performed structural fill compaction evaluation. Based on the results of our
inspections/evaluation, we confirmed that over-excavated areas were backfilled with approved
structural fill compacted to the equivalent ol95% of ASTM D69B maximum dry density, along with
the placement of a geogrid as per the recommendations given in the original geotechnical report.
Based on the results of our field inspections/evaluation, we approved the final subgrades
prepared for concrete placement, provided all the drainage recommendations are followed
throughout the design life of the structures.
We appreciate the opportunity to provide the geotechnical services to you
Sincerely,
