The settlement is <br /> likely due to inadequately compacted soil under the foundation or being built on fill soil. I <br /> recommend that four (4) helical piers be installed under the generator pad with two pads at each <br /> side starting at about the middle of the pad shown below. These 2718-inch diameter piers will <br /> allow the foundation to be lifted to a more level condition and be permanently supported against <br /> future settlement. <br /> i -& -rt <br /> k <br /> i <br /> tea"` y"�`k �'• ,.* Al <br /> 1 s.- a.N - k _- <br /> -'*` •.. 4* <br /> r al <br /> 1 <br /> �E LAIR:. � <br /> ,R M,.a r �' 5 tl III V� 4 �( <br /> r + <br /> r <br /> L' e ,p,, <br /> View of the Generator Pad from the West — Settlement Greatest at South End <br />
