About this detail

A structural opening less than two feet wide is cut into a metal deck with concrete fill. Additional number three reinforcing bars extend one foot six inches minimum past each edge of the opening typically on each side, supplemented by number four bars three feet long at each corner. Channel channels sized C4x5.4 are placed open side up on top of the deck and extend three deck high flutes past the opening typically. Openings are to be blocked out with the deck left intact prior to the concrete pour and may be removed after the concrete has cured.
