As requested, CTL I Thompson, lnc. made a site visit on July 23, 2A20 b
the location of the shop building being constructed on Lot 5 of the Quicksilver
Court Subdivision (a.k.a. 1375 Quicksilver Court) in Garfield County, Colorado.
The purpose of our visit was to observe the soils exposed in the foundation exca-
vation for the building. Footíngs for the building were constructed prior to our
visit. A copy of our excavation observation report and photographs from our site
visit are attached.
CTL I Thompson, lnc. performed a geotechnicalengineering investigation
for the shop building on Lot 5 (Project No. GS06392.002-120; letter dated June
22, 2020). Subsoils exposed in the bottom of the excavation, adjacent to the
footings, were clayey gravel and cobbles. These soils are as anticipated from
our geotechnical engineering investigation and suitable for support of footings.
We are available to discuss the contents of this letter. lf you have ques-
tions or need additional information, please call.
