Our evaluation is based on the borings <br />performed and our Report of Geotechnical Exploration provided by Nutting Engineers on <br />June 16,2004. <br /> <br />We also note that an additional two-story recreation building will be constructed at the <br />subject site. Based on discussions we understand that a prior geotechnical report was <br />provided for the building dating back to approximately 2000 to 2002. At this time we <br />were unable to locate any report in our records that indicate that the boring was <br />performed by Nutting Engineers along with the .understanding that the report could not be <br />loc~ted as well by Miller Legg and Associates. Therefore the recommendations provided <br />herein may be used for the two story structure along with the proposed gymnasium <br />however prior to construction we recommend that an additional soil boring be performed <br />within the building footprint to verify subsurface conditions. <br /> <br />Augercast Pile Analysis <br /> <br />Based on discussions with Mr. Carlos Sanz, P.E., the project structural engineer, we <br />understand that the proposed gymnasium will have column loads on the order of 210 kips <br />and wall loads on the order of 12 kips per linear foot. The two story building will have <br />wall loads on the order of 15 kips per linear foot. We understand that based on our <br />recommendations provided for a 40 ton pile the amount of piles required to support the <br />structure may be relatively high. Based on this we were requested to provide a higher <br />pile capacity to reduce the number of piles required for the proposed project. <br /> <br />1310 NEPTUNE DRIVE - BOYNTON BEACH, FLORIDA 33421- (581) 738-4900.
