The actual depths should be expected to vary <br />depending on the drilling conditions encountered during installation of these piles. Due to the <br />soil conditions encountered at this site, we anticipate large grout takes in order to construct the <br />cast-in-place piles. The floor slab and other site improvements should also be structurally <br />supported on the pile foundation system. If capacities other than 40 tons are needed, we should <br />be notified so that we may provide the capacity analysis based on revised loading information. <br /> <br />The Florida Building Code (FBC) requires that any piles designed for greater than 40 tons should <br />be load tested in order to verify the pile capacity. Therefore, a pile load test will not be required <br />for this project as described in the FBC. <br /> <br />AUGERCAST PILE CAPACITY TABLE <br /> <br />Pile Depth Below All. Compr. All.

Final pile installation criteria will be <br />provided at this time. It is important that the instaIJation of all piles be under the full time <br />observation of a representative of Nutting Engineers. <br /> <br />Pile Reinforcement <br /> <br />We recommend that at a minimum, one full length #6 reinforcing steel bar utilizing centralizers <br />be installed in each pile. Additional reinforcing may be required depending on the structural <br />engineer's requirements. <br /> <br />LJ We recommend that a structural engineer be retained to determine the spacing and locations of <br />the piles, and discussions should be initiated between the owners, structural engineer, contractor, <br />(\ and Nutting Engineers to provide detailed specifications for the foundation installation work. <br />u <br /> <br />n <br /> <br />LJ <br /> <br />(I <br /> <br />~NUTTING <br />,~ ENGI~~:~A~NC. <br /> <br />ESTASUSHED 1987 <br /> <br />5 <br />
