False Ceiling Verification Checklist

Essential Checklist+

Complete these critical checks before approving the work or proceeding to the next construction stage.

✓19 Inspection Points
✓5 Verification Categories
✓Room Measurement+
  • Room dimensions were measured on site — length and width at ceiling level, not floor level.
  • For irregular or L-shaped rooms, the room was divided into rectangles and each section measured separately.
  • Existing ceiling height and proposed false ceiling height were both recorded to confirm available void depth.
  • Minimum void depth of 100mm was confirmed — required for light fixtures, AC ducting, and grid clearance.
  • Dimensions were entered in consistent units — all metres or all feet, not mixed.
✓Grid and Board Selection+
  • Grid module size (600×600mm or 600×1200mm) was confirmed before calculating tile and grid quantities.
  • The ceiling board type — gypsum, calcium silicate, mineral fibre, or PVC — was confirmed as appropriate for the room use.
  • Moisture-resistant board is specified for kitchens, bathrooms, and areas with high humidity.
  • Board size matches the grid module — 600×600mm boards with a 600×600mm grid, not mixed module sizes.
  • Cut boards at room perimeter were included in the quantity — perimeter boards are always partial.
✓Grid Frame and Suspension+
  • Main runner spacing matches the grid module and the board span capacity — typically 1200mm c/c for standard gypsum.
  • Cross-tee spacing was confirmed against the grid module — 600mm c/c for 600mm module.
  • Hanger wire spacing does not exceed 1200mm along main runners — closer spacing required near heavy light fixtures.
  • Hanger wires are fixed to the structural slab or beams — not to services, conduits, or non-structural elements.
✓Structural and Services Coordination+
  • Structural engineer approval was obtained for additional point loads — heavy light fittings, AC units, or concealed tanks above the ceiling.
  • Electrical, plumbing, and HVAC services above the false ceiling were coordinated with the false ceiling grid layout before installation.
  • Access panels were specified at locations requiring future maintenance — valve bodies, junction boxes, AC drain pans.
✓Wastage and Order+
  • Wastage of 10% was applied to board quantity to account for cut boards at perimeter and breakage.
  • The final quantity including wastage — not the net area — was used for purchase.

✓Room Measurement+
  • Room dimensions were measured on site — length and width at ceiling level, not floor level.
  • For irregular or L-shaped rooms, the room was divided into rectangles and each section measured separately.
  • Fixed exclusions — light fixtures, AC duct openings, beam drops — were identified and their impact on grid layout noted.
  • Existing ceiling height and proposed false ceiling height were both recorded to confirm available void depth.
  • Minimum void depth of 100mm was confirmed — required for light fixtures, AC ducting, and grid clearance.
  • Dimensions were entered in consistent units — all metres or all feet, not mixed.
✓Grid and Board Selection+
  • Grid module size (600×600mm or 600×1200mm) was confirmed before calculating tile and grid quantities.
  • The ceiling board type — gypsum, calcium silicate, mineral fibre, or PVC — was confirmed as appropriate for the room use.
  • Moisture-resistant board is specified for kitchens, bathrooms, and areas with high humidity.
  • Fire-rated board is specified where required by the building's fire compartmentation or NBC 2016 requirements.
  • Board size matches the grid module — 600×600mm boards with a 600×600mm grid, not mixed module sizes.
  • Cut boards at room perimeter were included in the quantity — perimeter boards are always partial.
✓Grid Frame and Suspension+
  • Main runner spacing matches the grid module and the board span capacity — typically 1200mm c/c for standard gypsum.
  • Cross-tee spacing was confirmed against the grid module — 600mm c/c for 600mm module.
  • Hanger wire spacing does not exceed 1200mm along main runners — closer spacing required near heavy light fixtures.
  • Hanger wires are fixed to the structural slab or beams — not to services, conduits, or non-structural elements.
  • Wall angle (perimeter channel) length accounts for the full room perimeter including door openings.
  • Additional hanger wires were specified at 300mm from all grid joints and at each light fixture location.
  • Suspension wire gauge (minimum 1.6mm GI wire for standard loads) was confirmed.
✓Structural and Services Coordination+
  • Structural engineer approval was obtained for additional point loads — heavy light fittings, AC units, or concealed tanks above the ceiling.
  • Electrical, plumbing, and HVAC services above the false ceiling were coordinated with the false ceiling grid layout before installation.
  • Access panels were specified at locations requiring future maintenance — valve bodies, junction boxes, AC drain pans.
  • The false ceiling void was inspected and cleared of construction debris before boarding was completed.
  • Fire sprinkler heads (if present) were coordinated to protrude through the false ceiling at the correct grid module.
✓Wastage and Order+
  • Wastage of 10% was applied to board quantity to account for cut boards at perimeter and breakage.
  • Wastage of 5–8% was applied to grid components for cutting to room dimensions.
  • The final quantity including wastage — not the net area — was used for purchase.
  • Boards were ordered in the same lot or batch to ensure colour and texture consistency.
  • Storage conditions on site were confirmed — gypsum boards must be stored flat, off the floor, away from moisture.
  • Delivery access for full-length main runners (typically 3.6m or 3.7m) was confirmed before ordering.
