- Wall junction locations are verified.
✓Bond and Joint Verification+-
- Blocks are laid with proper running bond pattern.
- Vertical joints are staggered correctly.
- No continuous vertical joints are present.
- Adhesive is applied uniformly on all contact surfaces.
- Horizontal joint thickness is approximately 2-3 mm.
- Vertical joint thickness is approximately 2-3 mm.
- Joint thickness is consistent throughout the wall.
- Block joints are fully filled without gaps.
- Proper interlocking is maintained at corners and junctions.
- No dry-laid blocks without adhesive are present.
- Adhesive squeeze-out at joints confirms adequate coverage.
✓Alignment and Plumb Verification+-
- Wall is plumb vertically.
- Wall alignment is straight horizontally.
- Corners are square and accurate.
- Wall surface is even without noticeable undulations.
- String lines are used during construction.
- Frequent level checks are performed.
- Wall dimensions are periodically verified.
- Block courses remain level throughout construction.
- Plumb is checked at minimum every 5 courses.
- Cumulative level deviation is corrected before it becomes unmanageable.
✓Reinforcement and Connection Verification+-
- Reinforcement is provided where specified.
- Wall ties are installed where required.
- Connections to RCC columns are provided as specified.
- Connections to RCC beams are provided as specified.
- Anchor fasteners are properly installed.
- Control joints are provided where required.
- Reinforcement locations match approved drawings.
✓Openings and Service Verification+-
- Door openings match approved dimensions.
- Window openings match approved dimensions.
- Lintel bearing length is adequate.
- Electrical conduits are installed correctly.
- Plumbing sleeves are installed correctly.
- Service chases are cut neatly without excessive damage.
- Large service openings have proper support reinforcement where required.
- Embedded fixtures are correctly positioned.
✓Before Plastering Verification+-
- Wall surface is checked for hollowness.
- Loose adhesive is removed from wall surfaces.
- Surface irregularities are corrected.
- Wall alignment and plumbness are rechecked.
- All service installations are completed.
- Cracks or damaged blocks are repaired.
- Wall is cleaned before plastering.
- Surface preparation matches plaster system requirements.
- All block chases for electrical and plumbing are completed before plastering.
- Expansion joints between AAC wall and RCC frame are clean and correctly filled.
✓Final Approval+-
- Wall dimensions match approved drawings.
- Wall alignment and plumbness are verified.
- Joint quality meets project requirements.
- All openings are correctly positioned.
- Reinforcement and wall ties are approved.
- Photographs are taken for project records.
- All punch-list items are closed.
- Approved to proceed with finishing works.
Inspection Notes+-
Use this checklist with the latest approved architectural, masonry, and service drawings.
Check first course level, block bond, joint thickness, wall ties, openings, and embedded services before plastering.
Record non-conformances clearly and confirm rectification before finishing work starts.

Common Mistakes+-
Poor First Course Level
A small error in the first course can continue through the full wall height. Check base level, corner blocks, and reference lines before continuing masonry.
Incorrect Adhesive Thickness
AAC block adhesive joints are usually thin. Excessive or uneven joint thickness can reduce alignment quality and increase material consumption.
Missing Wall Ties and Service Checks
Wall ties, column connections, conduits, sleeves, and service chases should be confirmed before finishing because correction later can damage completed blockwork.

FAQ
Inspect blockwork during laying for first course level, wall line, plumb, bond, joint filling, and service openings, then inspect again before plastering or finishing work begins.
Yes. The checklist covers general block masonry checks. For AAC blocks, also verify adhesive quality, thin joint thickness, handling, storage, and manufacturer recommendations.
No. It supports site inspection, but block type, wall thickness, adhesive or mortar, wall ties, openings, and reinforcement must follow approved drawings and project specifications.
