PRESENTATION <br />OF <br />ONE ENETRATION EST DATA <br />1. INTRODUCTION <br />This report presents the results of a Cone Penetration Test (CPT) program carried out for the <br />First American project located in Santa Ana, California. The work was performed by Kehoe <br />Testing & Engineering (KTE) on July 29,2003. The scope of work was performed as directed <br />by MACTEC personnel. <br />2. SUMMARY OF FIELD WORK <br />The fieldwork consisted of performing CPT soundings at two locations to determine the soil <br />lithology. The groundwater measurements were taken in the open CPT hole approximately 10 <br />minutes after completion of CPT. A Pore Pressure Dissipation Test (PPDT) was performed at <br />location CPT-2 at a depth of 31.4 feet. The static water level resulting from the PPDT was <br />approximately 15 feet. The following TABLE 2.1 summarizes the CPT soundings performed: <br />DEPTH OF <br />LOCATION CPT (ft)COMMENTS/NOTES: <br />CPT-1 75 Seismic <br />CPU 75 <br />TABLE 2.1 - Summary of CPT Soundings <br />3. FIELD EQUIPMENT & PROCEDURES <br />The CPT soundings were carried out by KTE using an integrated electronic cone system <br />manufactured by Vertek. The CPT soundings were performed in accordance with ASTM <br />standards (D5778). The cone penetrometers were pushed using a 30-ton CPT rig. The cone <br />used during the program was a 15 cmA2 cone and recorded the following parameters at 2.5 cm <br />depth intervals: <br />• Cone Resistance (qc) •Indination <br />• Sleeve Friction (fs) •Penetration Speed <br />• Dynamic Pore Pressure (u) •Pore Pressure Dissipation (at selected depths)
