Re: Report of Geotechnical Exploration (GFA Project No. 18-9005.00) dated
October 1.5, 2018
Dear Mr. Hinkle:
Representatives of GFA International, Inc. (GFA) were requested to monitor the installation of
augered cast -in -place (ACIP) piles located at the above referenced property on March 5, 2019.
ACIP Pile Monitoring
The grout pump was calibrated on -site with the pump strokes required to fill a 55-gallon drum
(7.35 cubic feet). The grout pump strokes necessary to fill the theoretical pile volume plus 10
percent (grout factor) were then calculated to determine the required number of pump strokes
for each pile. The monitored piles had at least the minimum number of required pump strokes
and grout factor and/or sufficient grout head.
The data recorded during the pile installation are contained on the attached Augercast Piling
Inspection Forms. The pile numbers indicated on the forms correspond to numbers shown on
the Pile Layout Plan attached to this report. The pile lengths noted on the logs are based on the
depths below the existing ground surface at the time that the piles were installed. The steel
reinforcing for the piles was also observed to be constructed and placed in general compliance
with the provided project plans.
Note that during the installation of Pile No. 40, the grout hose became clogged. This resulted in
having to re -auger and regrout the pile as -Pile No. 40R.
Grout samples were obtained during the pile installation for compression strength testing.
These test results will be submitted under separate cover as they become available.
Conclusions
Based upon our observations and testing, GFA concludes that the ACIP piles have been
installed in general accordance with the design criteria, the project plans, and recommendations
provided in the above referenced Report of Geotechnical Exploration.
