Thread: Pier Graphic

I have spent the past hour looking for a decent graphic depicting a residential foundation drilled pier's rebar placement. Does anyone have something like this they would like to share?

Not sure if this is what your looking for but it's the best I could find.

JM: I guess I was not specific enough. That is for a foundation repair pier and what I need is for an original drilled pier. Thanks.

BJ: I'll attempt to remove the argot block. When one is building a pier and beam foundation one drills holes in the ground, adds rebar, and then fills the holes with concrete. The resulting entities are called piers. I am looking for a graphic depicting the proper placement of the rebar in these drilled piers. I suppose you could also call them augered piers. The IBC does, but no one here ever says "augered".

Something like the picture below, but a line drawing showing the whole hole, if you will.

Aaron,

It would vary depending on the engineering.

The size of the vertical steel, the number of vertical steel bars, the size of the hoops, the spacing of the hoops from the bottom and the top and each other will be specified by the engineer, which all depends on what is going to be placed on those piers, which also has to do with the number of piers installed.

JP: While this may be so, the minimal standards are set forth in IBC 1810, 1812, et al.
