Dear Mr. Fernandez:
Pursuant to your request, Dynatech Engineering Corp. (DEC) performed a Compaction Test on
June 22, 2022 at the above referenced project. DEC was authorized to perform a compaction test
only. The purpose of our test was to determine the degree of compaction of the tested layer of
material only. In no way shall a compaction test replace a demucking inspection, soil bearing
capacity determination, or a pad certification. A soil boring test must be performed by client if
not yet done, prior to construction to verify subsoil conditions. Underlying soils below test levels
must be verified to prevent future settlements. (DEC) was not authorized to perform supervision
and certification of the building pad preparation. This is not a pad certification. Our reports must
be provided to all involved parties for their approval.
Our findings are relative to the date and areas of our site work and should not be relied upon to
represent conditions on other areas or dates. Any subsequent site disturbances due to water
erosion, rain, storm gutters discharging at footings, construction activities, excavations,
overgrown, vegetation, traffic and other disturbances will void this test and the site must be re -
compacted and re -tested prior to construction.
Environmental analysis of the soil materials is not part of the scope of services. If environmental
analysis of the soils is required, we can provide a proposal for performing an environmental
analysis of the soil materials. No other analysis is implied or warranted.
As a mutual protection to clients, the public and ourselves, all reports are submitted as the
confidential property of clients, and authorization for use, publication of statements, conclusions
or extracts from or regarding our reports is reserved pending our written approval.
Enclosed find copies of the compaction test results. It has been a pleasure working with you and
look forward to do so in the near future.
Sincerely yours,
Wissam aamani, P. E.
