A portion of the foundation and building wall where settlement has occurred <br /> is to be stabilized and lifted. The wall has settled due to soft underlying soils. We have <br /> determined that underpinning for the structure will stabilize the impacted portion of the wall in <br /> the upper soils. <br /> The proposed method of underpinning is the use of helical piles. These are augured into the <br /> underlying soil until their load supporting capacity of approximately 11 tons is achieved. This <br /> stabilizes the effect of poor upper soil strata and discourages further raveling. The top of the <br /> pile connection system allows for adjustment and lifting of the floor to return the floor as nearly <br /> as possible to its original elevation. Pile spacing has been selected on the basis of anticipated <br /> relative soil density and imposed load from the structure. <br /> It is our engineering opinion that the proposed installation will, when complete, provide <br /> stabilization of the impacted portion of the floor in those areas where the underpinning is <br /> performed. <br /> NOTE: All RamJack helical piles have been certified as meeting ICC-ES, AC358, acceptance <br /> criteria for helical pile systems and devices (Mandatory Compliance Date December 1, 2013). <br /> In compliance with Florida statutes 627.707, this report was prepared under the supervision of a <br /> Registered Professional whose field of expertise is Structural and Geo-Technical Engineering. <br /> Sincerely�����`e,�'!Fd�����/� <br /> �� .��'.---�-.�'� �i� I <br /> `�� �;.-��c��s�,� %� , <br /> . .� � <br /> . � <br /> • ' ; � <br /> _ . . <br /> Paul €�i'agler sr�Te oF ,;��` �� <br /> FPE 2 5 � � <br /> a3 $.'. ,c A,r ? . <br /> %.F`�;�.�oR�o cy�.\�� <br /> cc: AI��J r���6a�$��c��LLC <br /> 9��i�1��������� <br />
