RE: Open Hole Observation
Lot 19, Westbank Ranch PUD Filing No. 4
778 Huebinger Drive
Garfield County, Colorado
Project No. 16-3105
DearWhit:
At your request and at the request from your excavator Jimmy, on May 2 and9,20I7 ,we visited the
construction site for the proposed residence on Lot 19, 'Westbank Ranch PUD Filing No. 4, at778
Huebinger Drive, Garfield County, Colorado. The purpose of our site visits was to observe the soils
exposed in the foundation excavations for the proposed residence and compare them with the findings and
recommendations of the Soil's and Foundation Investigation, under the same project number dated, dated
August 29,2016.
The excavation consisted of two benches for the main house and a "IJ" shaped perimeter trench for
the garage. During the first site visit the trenches for the grrage footings were not completed, and at the
northwest corner of the excavation was too shallow and still in topsoil. We recommended that the trenches
be excavated down to the brown, clayey sand with angular rock fragments.
The soil exposed in the excavation is suitablefor the recommended bearing capacity of 1000 psf;
however, there was still loose soil in parts of the excavation that would have to be scraped out before
concrete placement.
We recommend compliance with the recommendations of the above-named soil report during the
remainder of the construction, specifically with the sections on drainage, grading and irrigation.
This report has been prepared according to locally accepted Professional Geotechnical Engineering
standards for similar methods of testing and soil conditions at this time. The findings and recommendation
stated above are based on the soil conditions observed in the completed foundation excavation only.
There is no other warranty either expressed or implied.
Ifyou have any questions, please do not hesitate to call.
