- No visible cold joints on beam faces after striking
- Beam surfaces inspected for cracks — hairline cracks logged, structural cracks reported
- 28-day cube test results confirm specified concrete grade

Inspection Notes+-
Verify dimensions, reinforcement, cover, and formwork before concrete placement.
Confirm concrete grade, workability, compaction, and curing arrangements during the pour.
Inspect beam faces after formwork removal and escalate honeycombing, cold joints, cracks, or failed cube results.

Common Mistakes+-
Approving formwork without measuring internal dimensions
A small width or depth error changes beam concrete quantity and can reduce the constructed section. Measure the shuttering internally before reinforcement is closed.
Missing cover and lap checks before pouring
Incorrect cover, lap position, anchorage, or stirrup spacing may not be visible after concreting. Verify these items before pour approval.
Poor vibration and curing control
Congested beam reinforcement needs proper compaction and curing. Inadequate vibration, delayed curing, or early drying can lead to honeycombing, cracks, and durability issues.
