About this detail

Electrical conduits embedded within reinforced concrete slabs must be positioned within the middle third of the slab depth and kept at least four feet clear of column faces and slab shear reinforcing stud rails. Single groups are limited to three conduits maximum, requiring minimum spacing equal to the conduit diameter but not less than one inch clear from parallel reinforcing bars, and direct tying to reinforcing parallel to the conduit is prohibited. Crossing conduit layers are restricted to a maximum of two, and any placement in vertical elements like concrete columns or walls requires prior structural engineer approval.
