SUMMARY <br />OF <br />CONE PENETRATION TEST DATA <br />1.INTRODUCTION <br />This report presents the results of a Cone Penetration Test (CPT) program carried out for the <br />project located at 1241 S. Grand Avenue in Santa Ana, California. The work was performed <br />by Kehoe Testing & Engineering (KTE) on September 19, 2019. The scope of work was <br />performed as directed by Sierra Geotechnical Services Inc. (SGS) personnel. <br />2.SUMMARY OF FIELD WORK <br />The fieldwork consisted of performing CPT soundings at two locations to determine the soil <br />lithology. A summary is provided in TABLE 2.1. <br />LOCATION <br />DEPTH OF <br /> CPT (ft) COMMENTS/NOTES: <br />50 <br />50 <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 cm^2 cone and recorded the following parameters at <br />approximately 2.5 cm depth intervals: <br />Cone Resistance (qc)Inclination <br />Sleeve Friction (fs)Penetration Speed <br />Dynamic Pore Pressure (u)Pore Pressure Dissipation (at selected depths) <br />The above parameters were recorded and viewed in real time using a laptop computer. Data is <br />stored at the KTE office for up to 2 years for future analysis and reference. A complete set of <br />baseline readings was taken prior to each sounding to determine temperature shifts and any <br />zero load offsets. Monitoring base line readings ensures that the cone electronics are <br />operating properly. <br />72 of 100 <br />1327 S Grand Ave <br />12/12/2024
