City of Sunny Isles Building Department Relocation Geotechnical Exploration Report Sunny Isles Beach, FL March 29, 2024 UES Project No.: 0630.2400024.0000 Page 4 of 9 The following tests were performed to aid in classifying the soils and to help evaluate the general engineering characteristics of the site soils: percent passing the No. 200 sieve (ASTM D-1140) and Organic Content (ASTM D-2974). Table 1 below presents the summary of laboratory test results of the soils samples tested. Table 1 Summary of Laboratory Test Results Boring Sample Depth (feet) Percent Passing No. 200 Sieve (%) Organic Content (%) B01 9 – 10 - 9 B01 18 – 20 16 - B01 20 – 22 8 14 B02 18 – 20 21 11 Representative samples of the soils encountered during the field exploration will be held in the laboratory for your inspection for 30 days unless UES is notified otherwise. 2.3 Field Exploration For purposes of this study, two (2) standard penetration test (SPT) borings were completed to the deepest depth of 24 feet below existing grade. Figure 3 shows the approximate test locations performed at the site. The SPT boring method was used as the investigative tool within the borings. Penetration tests were performed in substantial accordance with ASTM Procedure D-1586, “Penetration Test and Split-Barrel Sampling of Soils”. This test procedure consists of driving a 1.4-inch I.D. split-tube sampler into the soil profile using a 140-pound automatic hammer falling 30 inches. The number of blows per foot for the second and third 6-inch increments is an indication of soil strength. The SPT borings were performed using a CME-55, a truck-mounted drill rig, equipped with an automatic hammer. The soil samples recovered from the soil borings were classified and stratified by a geotechnical engineer. Following completion of the field services, all boreholes were backfilled with excavated soil/rock, and the site generally cleaned, as required. The results of the classification and stratification are encountered during UES’s exploration are presented in Appendix A “Record of Test Boring”. It should be noted that soil conditions might vary between what is depicted on the attached log and other areas of the site. The soil boring data reflect information from a specific test location only. Site specific survey staking for the test location was not provided for UES’s field exploration. The boring locations, were marked in the field by a project engineer by using the provided aerials, measuring distances, and estimating right angles from existing site features.
