01 · Before pour
Create a signed hold point.
Before concrete arrives, verify the approved structural drawing, reinforcement and cover arrangements, formwork, joints, sleeves, conduits, inserts, cleanliness, access, compaction, sampling and curing plan. Photograph only after the responsible inspection is complete.
- Member and drawing revision
- Reinforcement, laps and cover devices
- Formwork line, level and support
- Joints, embeds and service sleeves
- Access, lighting and safe placement route
- Sampling laboratory and curing plan
02 · Pour record
Keep the concrete traceable to place and time.
Record supplier or batch information, ticket, time, location placed, authorized additions, workability tests, specimen IDs, weather, interruptions and compaction. Do not allow unrecorded site changes to water or mix.
- Pour card and member location
- Batch or truck ticket
- Test and specimen register
- Start, finish and interruption record
- Nonconformance or rejected load record
03 · Curing
Protect moisture and temperature as specified.
Record the curing method, start, protection, checks, interruptions and end. Avoid a universal seven-day or fourteen-day website rule: required duration depends on the specification, binder, weather, element and construction method. Also protect young concrete from damage and premature loading.
04 · Strength
Interpret results as a set of evidence.
Sampling and cube tests follow the project specification and current standards. One isolated result should not be treated as a direct load certificate for every part of a member. If results or site records are nonconforming, preserve traceability, issue a nonconformance record and let the structural engineer define investigation and action.
Rebound hammer, ultrasonic pulse velocity and cores are professional investigation tools. A rebound number alone does not prove grade or structural adequacy.
- Laboratory reports linked to pour IDs
- Engineer review and acceptance record
- No concealment or dependent work until released
- Approved investigation or repair method
- As-built and final nonconformance close-out
