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 loc ation, 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 X9K5 driver is to be employed. The X9K5 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 _29,000___ lbs. which is greater than the maximum calculated total load of _10,500___ lbs.
which occurs on the pile identified as no. _1__. Based on this analysis, the use of the X9K5 torque driver for the
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 20 20 7th 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 n oting depth and final torque installed for each pile.
3.Minimum pile depth to be 10’-0”
4.All pile calculations are based on a maximum spacing of 7’-0”.
5.Helical piles installed less than 48” apart are to be battered 10° away from each other.
6.This design is based on the loads of the structure placed on the shallow soils under the structure.
7.No deep soils geotechnical testing information was provided for this design.
8.This design does not address any possible sink hole activity as defined in Florida Statute § 627.706.
