Bracket assembly and forming system for building foundation

A system for retaining building material to form a portion of a foundation of at least a portion of a structure of interest, the system comprising:

• side walls receiving and retaining a flowable and curable building material therebetween, the side walls disposed in a predetermined configuration suitable for a portion of the foundation, the side walls including a first side wall and a second side wall, at least one of the first side wall and the second side wall is comprised of at least one component having an interior cavity;
• a bracket assembly retaining the side walls in the predetermined configuration, the bracket assembly including
• at least one inwardly bounding reinforcement post and at least one outwardly bounding reinforcement post, and
• a separator bar having a first end, a second end opposed from the first end, and a plurality of apertures disposed along a length of the separator bar, the plurality of apertures including a first set of apertures disposed proximate the first end and a second set of apertures disposed proximate the second end, the first set apertures and the second set of apertures are sized to receive and retain each of the reinforcement posts at locations corresponding to nominal widths of the at least one component and
• a barrier disposed between the outwardly bounding and inwardly bounding posts, the barrier including a fabric;
• wherein the at least one component of the at least one first side wall and second side wall is retained in the foundation after the building material cures;
• and
• wherein the barrier prevents backfill from filling a volume between the outwardly bounding and inwardly bounding posts.
