• Tiles (Mineral Fiber, Metal, PVC): Check for manufacturer's test certificates, edge finish, color consistency, and any physical damage.

• Framework: Ensure grid lines are perfectly straight, level, and at right angles. Suspension members must be vertical and securely fixed. Spacing as per design.
• Board/Tile Fixing: Boards/tiles should be fixed securely without undulations or damage. Joints should be uniform (for exposed grid) or properly finished (for seamless ceilings).
• Jointing (Gypsum/POP): Jointing compound applied smoothly, tape properly embedded, and sanded to a seamless finish. No visible cracks or tool marks.
• Cutouts: Openings for lights, diffusers, etc., should be neat, accurately sized, and reinforced if necessary.
• Edge Trims: Perimeter trims should be installed neatly, providing a clean finish at wall junctions.

• Levelness: Variation in level should generally not exceed ±3mm over a 3m length and ±6mm over the entire room/area. (Refer to CPWD specifications or specific project requirements).
• Alignment of Grid: Grid lines should be straight with a tolerance of ±1mm per meter, and not exceeding ±3mm over any 5m length.
• Gaps (Exposed Grid): Uniformity of gaps between tiles and grid members.
• Surface Finish (Seamless): No visible undulations when viewed from a distance of 1.5m. Surface should be smooth and ready for painting.
• Squareness of Grid: Diagonals of a grid module (e.g., 600x600mm) should not differ by more than ±2mm.

Note: Always refer to project-specific specifications, approved drawings, and relevant IS Codes (e.g., IS 8271 for gypsum board false ceilings, CPWD specifications) for precise quality standards and tolerances.
