<br /> Dear Bill:
<br /> As requested I have designed the placement of the helical soil anchors
<br /> and the steel beam to be used in repairing the existing foundation at
<br /> your home. The existing end of the house is supported by four 6x6
<br /> posts on concrete piers,which are to be replaced. You proposed to
<br /> replace the four piers with a continuous steel beam at the existing rim of
<br /> the main floor. The new steel beam will be supported by three helical
<br /> soil anchors augered into the ground and bracketed onto the steel beam.
<br /> I have attached a copy of the plan you sent to me showing the layout of
<br /> the framing and proposed locations of the beams and anchors. I have
<br /> inserted comments onto your plan specifying the location and required
<br /> working load capacities of the soil anchors and also the size of the steel
<br /> beam.
<br /> I recommend that 3 soil anchors be installed; one in the center of the 31'
<br /> long floor system and one located 3 feet from each end. The steel beam
<br /> will have a 3' cantilever at each end. I recommend using a W 6x25 steel
<br /> beam, which is 6 3/8"high by 6 1/8"wide and 25 pounds per foot in
<br /> weight. An alternative beam size would be a W 8x18, which is 8 1/8"
<br /> high by 5 '/4"wide, 18 pounds per foot. Either beam will work for the
<br /> repair. The soil anchor installer will install a bracket to the steel beam at
<br /> each anchor and can level up the beam as needed.
<br /> Let me know if you have any questions.
