About this detail

Square, rectangular, or round structural openings up to four feet in maximum dimension require two number five reinforcing bars placed diagonally at mid-depth of the slab at each corner. All top and bottom slab bars interrupted by the opening must be replaced with equivalent reinforcing split equally on each side and extended to achieve a Class B lap splice. Pipe and conduit sleeves through slabs or walls maintain a minimum clear spacing of three times the sleeve diameter or four inches, whichever is larger, with sleeve diameter limited to one-third the thickness or two inches maximum. Areas with inadequate clear distance between sleeves must be treated as a single framed opening with replacement reinforcing.
