Concrete after the truck arrives: placing, finishing and curing checks the site owns
The first half of the transit-shop slab looks ready for the finishers, but the shaded half still has surface water. Another truck arrives with a ticket that needs review. The pour record must connect these different conditions to the right locations.
Keep one timed record linking each delivery and test to the placed location, then continue it through finishing and curing. Use the actual specification, approved mix, pour plan and qualified people's instructions for the criteria. A completed pre-pour check does not settle what happens afterwards, and an acceptable slump result alone does not answer every question about a load.
Follow the concrete through the pour
- Check the incoming record. Match the ticket and mix identification to the approved requirement, note batching and arrival information, and identify the intended placement. Arrange the required qualified tests and record their references. Send an unexplained difference to the authorized people before treating the load as accepted; do not invent a universal delivery-age limit.
- Locate placing observations. Record when each defined area starts and finishes, interruptions, weather changes and departures the concrete foreman reports. Keep the agreed placement and consolidation controls available to that crew. Escalate concerns about an interruption or joint through the pour plan instead of directing an improvised repair from the site desk.
- Watch the finishing transition. Public concrete guidance distinguishes initial floating from later finishing and warns against later finishing while bleed water remains. Have the concrete foreman assess the actual surface and required finish. Record the affected area, observation, action and decision; the sunny bay's condition does not establish the shaded bay's readiness.
- Continue through curing. Confirm the specified curing and protection arrangements are ready before finishing ends. Record when the approved method starts, its location, checks and any interruption. Qualified personnel decide the actual method, conditions and duration; the management record must show what occurred, rather than simply say 'cured'.
Give the next shift a location plan and the current protection requirements. Identify who checks the continuing curing arrangement and who receives a departure. Keep delivery tickets, test references and later review together without rewriting the original times. This is a record of the work, not permission to remove protection, load the slab or strip forms.
Common mistakes
- Using one test result to approve every delivery concern.
- Recording the whole slab as one finishing condition.
- Ending the record before curing and protection checks.

Check your understanding
The sunny bay is ready for later finishing. Does that release the shaded bay?
