In accordance with your authorization, GeoSoils, Inc. (GSI) is presenting this interim final
report of rough grading, including sitework performed for the upper pad area of the
proposed structure. Grading and processing of original ground within the building
footprint, within the Street level floor/garage area portion of the building, was observed and
selectively tested by a representative of GSl during the earthwork phase of development
for the subject property. The work performed to date appears to be in general
conformance with the recommendations contained in Reference Nos. 1, 5, and 6, and with
the grading ordinance of the City of Carlsbad, California, from a geotechnical standpoint.
Field testing generally indicates that fills placed under the purview of this report, where
tested, have been compacted to a minimum 90 percent relative compaction per ASTM D-
1557. A final summary compaction report of rough grading for the project is forthcoming.
Expansion testing of soils exposed near building pad grade indicate an expansion index
(El) of less than 20. Unless specifically superceded herein, the conclusions and
recommendations with respect to foundation design/construction, presented in Reference
Nos. 2, 3, 5, and 6 remain pertinent and applicable and should be appropriately
implemented during project planning, design, and construction.
Unless specifically superseded herein, the conclusions and recommendations presented
in the referenced reports by GSI remain valid and applicable. The conclusions and
recommendations presented herein are professional opinions. These opinions have been
derived in accordance with current standards of practice, and no warranty, either express
or implied, is given. Standards of practice are subject to change with time. GSI assumes
no responsibility or liability for work or testing performed by others, or their inaction; or
work performed when GSI is not requested to be onsite, to evaluate if our
recommendations have been properly implemented. This report may be subject to review
by the controlling authorities.
