PREPARATION
Due to overhead obstructions, adherence to layout procedure is strongly recommended
Verify hanger support, lighting, and HVAC locations. Verify any MEP trades that may and will sit within the ceiling system. When possible, run
the ceiling grid main runners and ceiling wires opposite of overhead bar joists etc.
Install ceiling system per ASTM C636 with any additional requirements as noted within this manual
Lay out perimeter grid members and main runners on the floor directly underneath their installed positions per submittal drawings. Ensure floor
is clean to prevent damage occurring to the grid finish.
Install 12-gauge pre-stressed hanger wires on maximum 48” centers in line with main runners and within 6” of perimeter grid members. Install
the ceiling wires in locations to allow for proper installation of all trades.
Suspend wires by method or device whose suitability has been demonstrated by standard construction practice or by certified data. Suspension
wires are not to be installed more than one in six out of plumb unless a countersloping wire or horizontal bracing is provided. Suspension wires
are not to press against insulation, duct work, pipes, or other items within the ceiling plenum. Refer to ASTM C636 for allowable countersloping
methods.
Where width of ducts, cable trays, and other construction within ceiling plenums causes hanger spacing to interfere with the location of hangers
required to support ceiling system members, install supplemental suspension members and hangers in the form of trapeze or equivalent Archi-
tect / Engineer approved devices. Supplemental suspension members and hangers must be sized to support ceiling loads within performance
limits established by referenced standards.
