Lauderdale, Florida 33309 Subject: Report of Augercast Pile Installation Monitoring Proposed Medina Residence Lot 50, 4876 Watersong Way Hutchinson Island, Florida Dear Mr. Barnes: 1JIUIYCJJ&U11W V11YC Boynton Beach, Florida 33426 561-736-4900 Toll Free: 877-NUTTING (688-8464) Fax: 561 -737-9975 Broward 954-941-8700 St. Lucie 772-408-1050 Miami -Dade 305-557-3083 www.nuttingengineers.com 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 47, 14-inch diameter augercast piles for the project. The piles were installed from September 21 to September 22, 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 May 11, 2017. 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�• &li Pile, Location Plans attached. Each pile record in the attached summary tables shows the following information: OFFICES Palm Beach Miami -Dade St. Lucie ■ 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 File Copy ■ 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, #5 reinforcing bars with #3 ties spaced 10-inch on center, and a central #7 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. Our client for this project was: Mr. Rich Barnes Bodax Foundations, Inc. 1101 NW 55t' Street Ft.
