(a) Inspection of subgrade of footings, piers and walls shall comply with the requirements of section 46 of this subchapter:

1. Design:

i. Concrete footings: Concrete footings shall be proportioned in accordance with the requirements of this section. Reinforcement shall extend to within four inches of the edges of the footing.

ii. Masonry footings: Masonry used for construction of footings shall be solid units.

(1) Reinforced masonry footings shall meet the building code requirements for reinforced masonry--U.S.A.S.I.--A-41.2 (1960), and shall be proportioned similarly to the proportioning of reinforced concrete footings;

(2) Unreinforced masonry footings shall be of such dimension that a sloping plane extending downward from the top of the footing where it intersects the pier of wall, to the bottom of the footing, and measured at the angle with the horizontal that is indicated below, will be contained entirely within the footing:

(A) Soil bearing capacity of three tons per square foot or less--60 degrees;

(B) Soil bearing capacity between three tons per square foot and six tons per square foot--70 degrees;

(C) Soil bearing capacity greater than six tons per square foot shall be investigated;

(D) The compressive stress in the footing, based on the assumption that the vertical load is uniformed distributed over horizontal sections bounded by said planes, shall not exceed the values as required by design standards of this subchapter.
