Cool and Cobb Engineering Company <br /> Date: 1/7/20 <br /> Job: Ted Hamilton <br /> Location: 5319 1111 St <br /> Zephyhills, FL 33542 <br /> PILING DESIGN ANALYSIS <br /> The load requirements for the pilings designed to assist in supporting the identified areas of the subject <br /> residence were determined.The selected piling locations and the specific piling are identified on the Pier <br /> Identification and Location Plan attached.The calculated total loads on the piles in the specific location, <br /> including both dead and live loads are documented in the attached table which is designated as Attachment"A". <br /> Based on the total load requirements for each of these piles,the push pier driver is to be employed.The push <br /> pier driver should be employed with a calculated load of 21,600 lbs.,which will provide pile capacity, <br /> including the 2 to 1 safety factor of 43,200 lbs.which is greater than the maximum calculated total load of <br /> 41,000 lbs.which occurs on the pile identified as no. A-1 . Based on this analysis,the use of the push pier <br /> driver for the helical piles with a specific load of 21,600 lbs. and a minimum depth of 15'is approved and <br /> certified as meeting all the requirements of the Florida Building Code 2017 6`h Edition,and good engineering <br /> practice.This is not to be the primary support structure, but a supplement support to assist in support of the <br /> weight of the structure,which will reduce the total pressure on the existing soils.After completion of <br /> installation,Cool and Cobb Engineering Company shall be supplied with a drilling log of the location and depths <br /> of each pile installed so they can evaluate the installation and prepare the"As Built"drawings. <br /> General Notes: <br /> 1. All piles to be installed in accordance with ICC ES AC 358 <br /> 2. A log of each pile to be kept by Contractor noting depth for each pile. <br /> 3. Piles installed less than 48"apart are to be battered 10°away from each other. <br /> 4. This design is based on the loads of the structure placed on the shallow soils under the structure. <br /> 5. No deep soils geotechnical testing information was provided for this design. <br /> 6. This design does not address any possible sink hole activity as defined in Florida Statute§627.706. <br /> 1/7/20 ALL WORK SHAD COMPLY wITH PREVAILING <br /> Carl Cooi;P.E.
