About this detail

Procedures for creating penetrations up to 6 inches in diameter within a composite slab require concrete to be blocked out prior to pouring, with metal deck cutting deferred until the concrete reaches 75% of its design strength. Cutting the deck is limited to no more than one web per hole location. Maintain a minimum spacing between penetrations of six times the diameter of the larger opening, or at least 12 inches. If opening sizes or spacings exceed these limits, reinforce the assembly according to the requirements specified in detail 2/S-62001.
