- Remodel garage to eliminate center post and replace 8 ft doors with single 16 ft door
- Existing 2nd floor joists unaffected by new beam
- Existing wall pier between doors is only 8" wide and is not providing any shear support. Therefore
shear walls are unaffected by this change.

Existing footings are adequate to take the increased gravity load and stay below the allowable
1500 psf code minimum bearing capacity.
Bending stresses in footings are minimal and OK by inspection.
