PILING DESIGN ANALYSIS
The load requirements for the pilings designed to assist in supporting the identified areas of the subject
residence were determined. The selected piling locations and the specific piling are identified on the Pier
Identification and Location Plan attached. The calculated total loads on the piles in the specific location,
including both dead and live loads are documented in the attached table which is designated as Attachment "A".
Based on the total load requirements for each of these piles, the 5k driver is to be employed. The 5k torque
driver should be employed with a selected gauge pressure of 1,000 psi, which will provide pile capacity,
including the 2 to 1 safety factor of 11,463 lbs. which is greater than the maximum calculated total load of
5,600 lbs. which occurs on the pile identified as no. A-14 . Based on this analysis, the use of the 5k
torque driver for the Ram Jack piles with a specific gauge pressure of 1,000 psi and a minimum depth of 10'
is approved and certified as meeting all of the requirements of the Florida Building Code 2017 61h Edition, and
good engineering practice. This is not to be the primary support structure, but a supplement support to assist in
support of the weight of the structure, which will reduce the total pressure on the existing soils. After
completion of installation, Cool and Cobb Engineering Company shall be supplied with a drilling log of the
location and depths of each pile installed so they can evaluate the installation and prepare the "As Built"
drawings.
General Notes:
1. All piles to be installed in accordance with ICC ES AC 358
2. A log of each pile to be kept by Contractor noting depth and final torque installed for each pile.
3. Minimum pile depth to be 10'-0"
4. Helical piles installed less than 48" apart are to be battered 10' away from each other.
5. This design is based on the loads of the structure placed on the shallow soils under the structure.
6. No deep soils geotechnical testing information was provided for this design.
7. This design does riot address any possible sinkhole activity as defined in Florida Statute § 627.706.
