The Contractor shall deliver to the Owner extra acoustical panels of each type and color installed, equal to the specified percentage of the installed area of that type, for the Owner's future maintenance and replacement. Acoustical panels are routinely damaged, stained by plumbing leaks, and removed for plenum access over the life of a building, and the panel finish and shade are difficult to match exactly with later production; attic stock from the original lot ensures that replacements match the installed ceiling. A 2 percent attic stock is a reasonable default; spaces with frequent plenum access or higher exposure to leaks warrant more. Extra material shall be delivered in the original packaging, clearly labeled with the panel type and color, and stored where the Owner directs.
