Run a concrete pour from request to record

Raise the pour request with the element, the location, the specified mix and the volume, giving enough notice for the inspection and the concrete order to line up.

Zašto: A pour called at short notice is a pour that skips checks. Requesting it properly gives the inspection its window and the batching plant its lead time, so nothing is rushed on the day.

Inspect against the checklist before the pour: reinforcement size and spacing, cover, ties, formwork line and cleanliness, and any cast-in items in the right place.

Zašto: This is the last moment the steel and the formwork are visible. A hold point cleared here catches the error that would otherwise be entombed and only found when the cover meter comes out.

Release the hold point and pour, logging each delivery ticket, the mix and slump on arrival, and taking the cube samples for testing as the concrete goes in.

Zašto: The tickets and samples captured during the pour are the proof the right concrete went in. Reconstructed afterwards they are worthless, so they have to be taken as it happens.

Record the cube test results at seven and twenty-eight days against the pour, and close the as-built record for the element, so the concrete has a verified strength on file.

Zašto: A pour is not finished when the concrete sets, it is finished when it is proven to strength on record. That record is what the structural sign-off and the eventual handover depend on.
