w = Equivalent-fluid weight of soil, lbs/cu. ft. = 35 psf.
W = Total lateral load, lbs/linear foot of wall
c = Location o W below finished grade
R = Reaction at top of wall
R1 = Reaction at base of wall
x = Location of maximum moment below ground level, feet.
M = Maximum moment, foot-lbs/linear foot of wall

Note: Panel foundations can be site built or made in a shop. When made so it cover up items that need inspection by the Building Inspector. Third Party Inspection may be required. (inspect for grade stamps, treatment stamps, stud spacing, insulation, nailing, dip of saw cuts, plywood requirments are some of the item that a third party inspection will note.

All current Building Codes Standards

While wood foundations are easy to build, this is only true if one is building from an accurate well designed plan. When such a plan is incorrect, or if something is left out of the plan or absent, or if a design is made using a guide manual (these are not design manuals); major mistakes can be made during the construction process. These errors cause problems for the owner, builder, and the building department.
