Nutting Engineers of Florida, Inc. (NE) has completed observation of augercast piling operations
for the proposed residence and pool at the subject site. Bodax Foundations, Inc. installed cast -in -
place augured piles for support of the proposed construction.
Bodax Foundations, Inc. installed a total of 56, 14-inch diameter augercast piles for the project.
The piles were installed from December 7 to December 14, 2017. Please refer to the pile plan
for the numbering provided to our office. The pile size and depth recommendations were based
upon our review of the Report of Geotechnical Exploration prepared by GFA International dated
August 12, 2015.
The pile installation characteristics of each pile are presented in the attached Pile Installation
Data. Identification of each pile location followed by the pile number is shown on the Pile
Location Plans attached. Each pile record in the attached summary tables shows the following
information:
OFFICES

■ RECORD NUMBER IN CHRONOLOGICAL ORDER
■ THE PILE NUMBER (AS FOUND ON ATTACHED PLANS)
■ THE DIAMETER OF THE PILE
■ THE LENGTH OF PILE FROM GROUND SURFACE TO TIP
■ THE THEORETICAL VOLUME OF GROUT FOR THE PILE
■ THE NUMBER OF PUMP STROKES FOR THE PILE
■ THE ACTUAL VOLUME OF GROUT FOR THE PILE,
■ THE GROUT FACTOR
■ THE DATE OF INSTALLATION
■ THE REINFORCEMENT TYPES nk
■ AND GENERAL COMMENTS AS NEEDED
The drilling operations were monitored in the field by our field engineer and inspector in order to
approximately determine the type of material being penetrated. This identification was done
based on the augering time, the materials received during the drilling operations and the relative
hardness of the soils/rocks as indicated by the vibration or "chattering" of the hydraulic lines.
The augercast piles were installed to depths of twenty-five feet below the existing ground surface
which was approximately three to four feet below adjacent crown of road elevations. The .piles
were designed for an allowable compressive capacity of 30 tons as required by the structural
specifications.
Generally, during the installation of the piles, easy drilling was observed from the ground level to
approximately twenty feet. Below this depth range hard drilling was encountered to the final tip
depth.
All piles received steel reinforcement consisting of an upper fifteen -foot cage with 4, 45
reinforcing bars with #3 ties spaced 10-inch on center, and a central 47 full length reinforcing bar
as stated in the structural documents.
Upon completion of this inspection process, and review of the recorded data, it is our opinion
that the augercast piles installed for the residence attained the required design compressive
capacity of 30 tons. The piles that were presently installed were constructed in substantial
compliance with the plans and specifications.
We note that it was monitored and ensured that the piles began installation at the survey locations
provided in the field. If during drilling operations it was discovered that gross deviations from
original locations have occurred, the deviation was attempted to be rectified. Nutting Engineers
is not responsible for minor deviations which have occurred during drilling operations, along
with incorrect surveyed pile locations during piling installation. We also note that some
deviations may be due to the augerdrill shifting when attempting to drill through the hard rock or
other encountered debris conditions. This condition is beyond the control of the site inspector
and undersigned engineer.
