<br />Nationwide Insuranc6 - Center for Radiation Oncology, 7315 Green Slope Drive, Zephyrhills, FL <br />-Lab No. 190442 <br /> <br />Page 8 <br /> <br />factor of 1/4 is generally used to relate penetrometer resistance (kg/cm2) to "N" <br />value. <br /> <br />Hand Auger Borings <br /> <br />Hand auger borings numbers HA 1 through HAS were conducted around the <br />perimeter of the building. The actual test locations are plotted on Figure 2. <br />Detailed descriptions of the hand auger borings are included in the appendix of <br />this report. <br /> <br />Hand augers HA 1 through HAS found predominantly sandy soils followed by a <br />moderately plastic clayey sand layer. The clayey sand began at depths ranging <br />from 2.8 to 4.0 feet below land surface and extended to the termination depth of <br />each boring at 6.0 feet below land surface. The shallow ground water table was <br />not encountered in any of the hand auger borings at the time of the tests. <br /> <br />Static hand cone penetrometer tests were conducted at each of the hand auger <br />location and found the upper soils to be somewhat loose in the upper foot and <br />medium dense to dense or stiff below that depth. Individual charts of the <br />penetrometer readings taken at the hand auger locations are included in the <br />appendix of this report. <br /> <br />Test Pit Excavation <br /> <br />Two test pit excavations of the foundation were completed around the building to <br />determine foundation type, and to measure the foundation dimensions and <br />embedment depth. The actual test locations are plotted on Figure 2. In addition, <br />hand cone penetrometers were conducted in the test pits at I-foot intervals <br />beginning at the bottom of the foundation. <br /> <br />The test pit excavations completed found the building to be constructed on a <br />typical stem wall with a strip footing foundation system. <br /> <br />Test pit excavation TP 1 was completed on the east side of the building and found <br />the strip footing to be approximately 22 inches wide, 11 inches thick, and the <br />bottom of the footing was embedded 28 inches below grade. Test pit excavation <br />TP2 was completed on the south side of the building and found the strip footing to <br />be approximately 22 inches wide, 6 inches thick, and the bottom of the footing <br />was embedded 25 inches below grade. <br /> <br />According to the current Florida Building Code (Section 1804.13), the bottom of <br />foundations shall extend no less than 12 inches (305 mm) below finish grade. The <br />embedment depth of the foundation measured in both of the test pit excavations <br />exceeded this requirement. <br /> <br />Static hand cone penetrometer tests were conducted at each test pit location and <br />found that the soils present immediately below the foundation were medium <br />dense of denser from zero up to five feet below the foundation. Individual charts <br />of the penetrometer readings taken at the test pit locations are included in the <br />appendix of this report. <br /> <br />Standard Penetration Test Borings <br />Boring B-1 was drilled on the east side of the building near the damage noted in <br /> <br />Central Florida Testing Laboratories, Inc. <br />12625 - 40th Street North, Clearwater, FL 33762 <br />
