V.I.A. structures - General information
Use the centerline dimensions from the layout
drawing plan view to determine location of ceiling
track centerlines. Several methods can be used to
mark lines on the ceiling, including laser transit,
pencil marks on tape, chalk lines.
See pages 9 through 18 for additional ceiling track
information to determine cutting lengths for common
ceiling track conditions.
Transfer the ceiling centerline to the floor by means
of laser transits or plumb bob.
Make sure that the tape or lines are not visible after
install is complete.
For the best results use a 5-point
alignment self
leveling laser to transfer lines,
plumb, level and square
to within 1/32 of an inch. The most accurate
feature to reference, while leveling, is the vertical
post system hole shown on page 21 & throughout
various V.I.A. assembly directions.
