Remarks
A: Test results comply with specifications.
Comments
Tests are "Direct Transmission" (Method A) unless probe depth is noted as
"Backscatter". Gauge calibration data on file with the testing agency.
4: As requested, a site visit was made to observe placement and
compaction of the soils being utilized to achieve proposed footing
elevation. The contractor is moisture conditioning the previously
excavated soils and is placing and compacting the soils in 8" to 10"
lifts. Compaction is being achieved with a walk-behind vibratory
sheeps foot compactor. Results of density testing performed today at
the locations indicated met project specifications. The contractor was
notified of our observations and density test results. Future site visits
will be scheduled with our office if needed.
This report presents opinions formed as a result of our observations of fill placement and the test results shown above. Test data are not the sole basis for
opinions whether the fill meets project specifications. The contractor is responsible to apply necessary compaction effort and moisture to comply with project
specifications. Our test results, observations and opinions do not constitute acceptance of the work.
