The dynamic penetrometer tests were terminated at a depth of 14 feet elow existing grade, and the hand -auger borings at a depth of 6 feet below existing rade. The location of the test holes are indicated on the Boring Logs. )uring the portable dynamic penetrometer test, a 35 lb. (16 kg) safety hammer is lifted nd allowed to fall 15 in. (38 centimeters). Hammer blows are counted by the operator )r each 10 centimeters of penetration with the counting facilitated by scribes spaced at 0 centimeters on each 1 meter long rod. Blows per 10 centimeters of penetration, ynamic cone resistance and equivalent SPT `N' values are measured and shown on ie attached "Wildcat" logs. 3ased on our interpretation of the boring logs, it appears there are very loose/soft soil ayers below the proposed pool bottom. The very loose/soft layerx generally consists of ine-grained sand, a fine-grained silt/clay. The unsuitable soils were found to a depth of Ipproximately 8 feet below existing grade. At a depth of 8 feet the soils are medium- lense. Ronald G. Keller, P..E.: 37293 / SI Lic. No.: 860 / Julie E. Keller, P.E.: 68366 f KELLER, SCHLEICHER & MacWILLIAM ENGINEERING AND TESTING, INC.

Florida ►e believe the pool shell can be supported on a conventional pool foundation provided at the very loose and soft soil layers are removed from the pool bottom. This can be )ne by over excavating the pool and backfilling with 3/" stone so the subgrade :comes firm below the pool bottom. The rock should be compacted using a "jumping ck." visual inspection is also recommended to verify all unsuitable soils have been noved below the pool bottom. led that the site is properly prepared, the pool can be designed and constructed an allowable soil bearing pressure of 2,000 pounds per square foot, or less. Brbckfill material behind the pool shell shall consist of clean granular sand with less than 83,lpercent "fines" passing the U.S. No. 200 sieve. Place backflll material in loose lifts of 12 inches in thickness and compact each lift to no less than 95 percent of its modified 11 d Proctor value (ASTM D 1557). J osure: s report has been prepared in accordance with generally accepted soil and ndation engineering practices based. on the results -of the test- borings and. the ;umed loading conditions. This report does not reflect any variations which may :ur between the borings. If variations appear evident during the course of Istruction, it would be necessary to re-evaluate the recommendations of.this project. ��stttt►rr�� e A be of assistance to you on this phase of your project.
