About this detail

Conduits are embedded in concrete slabs over steel deck, detailing two distinct installation configurations for light and heavy conduit sizes. The light conduit assembly specifies a three-inch minimum concrete thickness above the deck with a one-half-inch diameter conduit, maintaining a three-quarter-inch minimum clearance and welded wire reinforcement placed over the conduit where required. Conduits require a three-inch minimum spacing and a one-foot-six-inch minimum spacing between runs, with shear studs welded to the underlying steel beam. The heavy conduit assembly requires a four-and-one-half-inch minimum concrete thickness with three-quarter-inch diameter conduit, maintaining a one-and-one-half-inch minimum clearance and an added reinforcing bar configuration consisting of minimum number four bars at twelve inches on center perpendicular to the conduits, extending one foot past the conduit on both sides.
