i <br /> A. M. ENGINEERING AND TESTING, INC. <br /> Geotechnical Exploration <br /> Indian River County Parks Maintenance Complex, IRC Project No . 0710 <br /> A . M . Engineering Project No . PSL1825 - 1 <br /> The proposed construction consists of three single story CBS buildings with associated parking f <br /> areas and a stormwater management area. The buildings range in size from 1 ,750 square feet to <br /> 3 ,600 square feet. A future 3 ,600 square foot addition is planned on the east side of the 3 ,600 <br /> square foot office building . Also a 2 ,400 square foot pole bam is proposed in the northeast <br /> corner near the stormwater management pond. Monolithic foundation systems are planned for <br /> the buildings . We have not received any information regarding loading for the structures. We <br /> estimate that the maximum column and wall loads will be 40 kips and 3 kips per linear foot, <br /> respectively. We estimate that 1 to 2 feet of fill will be required to raise the current grade of the <br /> site in the construction area to final design grade for the access drives and the foundation pad. <br /> If the actual loads are substantially larger than those estimated or the amount of fill is less, A. M . <br /> Engineering should be advised promptly so that we can review our recommendations and revise <br /> them if necessary. <br /> FIELD EXPLORATIONS <br /> The subsurface conditions at the project site were explored on April 11 , 2007 , with four (4) Cone <br /> Penetrometer (CPT) soundings and fifteen ( 15 ) Auger (AB) borings . Hand Cone Penetrometer <br /> (HCP) readings were taken at one-foot intervals in boring AB - 11 in the southwest corner of the <br /> proposed future office addition. The CPT soundings were performed in general compliance with <br /> ASTM D 3441 , "Deep Quasi-Static, Cone and Friction-Cone Penetration Tests of Soils", and the <br /> auger borings with ASTM D 1452, "Practice for Soil Investigation and Sampling by Auger <br /> Borings" . The HCP test, in conjunction with information about the soil type , is empirically <br /> correlated to the relative density of subsurface soils . <br /> The approximate locations of the explorations are noted on the Boring Location Plan. Access to <br /> portions of the southwest corner of the site was limited due to heavy vegetation. The borings <br /> were located based on the provided plans, tree survey and estimated distances to distinguishable <br /> landmarks. GPS coordinates obtained at each CPT location are included on the logs . The depths <br /> on the boring logs are below the ground surface at the time the borings were completed. <br /> USGS TOPOGRAPHICAL AND USDA SOIL SURVEY INFORMATION <br /> We reviewed the USGS 7 .5 -minute series quadrangle topographic map of the area, entitled Vero <br /> Beach. The map was revised based on aerial photographs taken in 1983 . The USGS map showed <br /> the project site is located in a relatively flat, low, wooded area with an elevation between 15 and <br /> 20 feet NGVD. The site is between the Atlantic Coastal Ridge on the east and the slightly higher <br /> savannas on the west. A mine or quarry with two lakes/pits is east and southeast of the project <br /> site, the water surfaces are between elevations 20 and 25 feet NGVD . The Lateral ` G ' Canal is <br /> located east of the project site and there are several small lakes and other canals in the area. <br /> The site is shown on sheet number 21 of the Soil Survey of the Indian River County Area, _ <br /> Florida, issued by the U .S . Dept. of Agriculture in January 1987 . According to the Soil Survey <br /> 2 <br />
