Guidelines for hanger attachment to a composite slab with concrete topping over wide-flange steel beams require that under Option 1 MEP devices be suspended directly from framing beams or supplementary framing provided by the MEP contractor, ensuring no loads are applied to the slab on metal deck. Option 2 permits alternate support strategies provided that anchor spacing and maximum supported loads comply with the demonstrated criteria, requiring a minimum two-foot spacing between post-installed anchors installed by the MEP contractor. The MEP contractor is responsible for designing and providing appropriate anchorage devices with sufficient holding capacity, and any conditions violating the allowable spacing and loading criteria must be submitted for approval.

NO LOADS ARE APPLIED TO THE SLAB ON METAL DECK. OPTION 2: ALTERNATIVELY, THE MEP CONTRACTORS MAY CHOOSE TO PLAN THEIR SUPPORT STRATEGY TO ENSURE THAT THE SPACING AND MAXIMUM SUPPORTED LOADS AT EACH HANGER ARE WITHIN THE LIMITS DEMONSTRATED IN THE DETAIL. NOTES: 1. IT IS THE MEP CONTRACTOR'S RESPONSIBILITY TO DESIGN AND PROVIDE THE APPROPRIATE ANCHORAGE DEVICES FOR ATTACHMENT TO THE STRUCTURAL ELEMENTS WITH SUFFICIENT HOLDING CAPACITY FOR THEIR INTENDED APPLICATION. 2. SUBMIT FOR APPROVAL CONDITIONS WHERE ALLOWABLE ANCHOR SPACING AND ALLOWABLE ANCHOR LOADING CRITERIA NOTED IN THE TABLE BELOW ARE VIOLATED.
