   There’s no dimensions for that

   Section A-A says 4 feet. Although not shown, the footings are 24 inches wide and 12 thick.

   However, the question was not about dimensions but terminology.

   I’m not a mason, just a dumb carpenter. If I were you I’d go to a masonry forum for the info.

   But.

   Having no idea what you are building, here’s a guess. Locally, the periodic enlarging of a footing might be called a spread or column footing. When the above load is concentrated and located along regular footings, those footings are enlarged.

   If this is incorrect and you do get an educated answer, please fill me in. My curiosity is killing me.

   Best of luck.

   I think I found the answer. I seems to be called a "grade beam" In the drawing that I posted, it is used with the spread footings to handle the lateral loads. The beam reduces the width of the wall footings. The basement wall is very tall and has about 10 feet of grade on one side.

   Thanks for the help.

   It is definitely not a grade beam. A grade beam is a reinforced concrete beam that sits on grade and is supported by pylons or concrete columns that penetrate to stable soil some distance below the beam. It is designed to span the distance between the columns. Although it sits on grade it is supported by the columns not the soil it rests on unlike a footing.

   One more thing. A grade beam does not have to be level like a footing. It can follow the grade. They are often used on difficult or extreme slopes.

   It is by no means clear what this footing is for. That's why I asked for dimensions. It looks like there might be a concret column on it in which case it's a column footing.

   A 12" by 12" column with rebar sits on the footing. The top view shows four dots that represent the rebar.

   Looks like a garage to me. or some kind of equipment shed. Is this to be put where flooding is a possibility? Or similar hazard that could push against the wall from the one side only? Seems like the purpose is to support the vertical columns, and aid in resisting horizontal forces on the wall.

   This still does not help you with a nomenclature, but it could just be that this feature is not common enough to have a short name.

   So a set of words could describe the feature. (and perhaps the purpose)

   Looks like a spread footing to support the column above (and I concur definitely not a grade beam)

   Seems to show a 2-car garage at the bottom of the plan view, with an 8'-8" high opening at section C-C. Maybe it's a pilaster footing, to support a fireplace and chimney above it? With 10 feet of fill on the outside, it could be additional footing width to counteract overturning from the lateral load.

   Looks like it could be plaster renforcmet to wall side load
