Run a concrete pour from request to record
Run the pour card loop end to end: raise the request, clear the pre-pour hold point, release and pour with the delivery tickets and cube samples, then record the test results and the as-built against the element.
Cách hoạt động, từng bước một
4 bước xuyên suốt nền tảng - bạn làm gì ở mỗi bước và vì sao điều đó quan trọng.
Raise the pour request
Biểu mẫu & danh mục kiểm traRaise 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.
Tại sao: 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.
Clear the pre-pour hold point
Kiểm traInspect 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.
Tại sao: 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 and pour
Construction ControlRelease 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.
Tại sao: 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 tests and as-built
Construction ControlRecord 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.
Tại sao: 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.
