Dear Mr. Shah:
GeoTek, Inc. (GeoTek) has provided geologic observations and geotechnical engineering
services during rough grading for the proposed single-family residence and associated
improvements at the subject site. GeoTel< has been retained on a full-time basis intermittently
between April 2015 to date.
Based on our observations and testing, rough grading operations have been completed thus far
in general accordance with City of Diamond Bar guidelines, 2013 CBC guidelines, and the
referenced geotechnical reports by GeoTek, Inc.
It is our understanding that the "upper level" of the residence is being prepared to be
constructed. This area is considered suitable for the intended construction from a
geotechnical viewpoint.
Conclusions and recommendations presented in the referenced reports remain valid and
applicable. A final geotechnical report summarizing the grading operations and presenting field
density tests for the project as well as other design and construction recommendations will be
prepared at the conclusion of the grading for the project site.
