Kelly, I think you are asking what does it mean and what would be
acceptable when the plans clearly state that center of tile is not
required. In my mind (which is not any standard btw), that note
means, "We are paying for decent sprinkler protection, not ceiling
ornaments. Don't figure any extra fittings or effort to spot the
sprinklers at exact tile locations and as long as you have a
competent crew that gets the sprinklers fairly aligned and
consistent, then expect trouble only for grossly sloppy work in the
most visible areas. " In other words acceptable work is what would be
reasonably expected of a competent fire protection contractor knowing
that center of tile is not specified. "Center of tile not required"
might also be expanded to mean, "A 15 foot spacing in a 2 foot
ceiling module is acceptable.", but you might ask about that a head
of time. The closer the sprinkler to the grid then the more likely to
expect trouble. The ceiling installer's error margin could easily put
you into grid trouble with a 15 foot spacing.
