General Comments
Date: September 4, 2015
As scheduled, a representative arrived on-site to perform the below discussed services and we have
the following comments.
***OPEN HOLE***
The compacted structural fill soils at the base of the excavation for the garage addition were observed, It is our understanding
that the recommendations of LKP Engineering, Inc. were followed, consisting of over -excavating 4' below bottom of footing
elevation and replacing with compacted 1 1/2" minus base course material improved with three layers of Tensar TX140 geogrid
placed at 6", 24", and 42" below bottom of footing. At an elevation of approximately 6410', the prepared materials were
comprised of Class 6 base course material placed above the structural fill section outlined in the project geotechnical
recommendations prepared by LKP Engineering, Inc., dated August 3, 2015, supplemented on August 6, 2015. The improved
structural fill section is therefore deemed capable of providing a maximum allowable soil bearing capacity of 2000 psf.
The exposed materials were prepared in accordance with project documents and tested for moisture and density (reported on
corresponding soil compaction report). Clint Omang was immediately notified of today's observations and test results,
