Pour Rate and Sequence: Follow the Temporary-Works Plan

Know the hazard

Team: Concrete Workers. Topic: Temporary Works.

The concrete truck queue can make faster placement feel like the answer to every delay. But rate, sequence, and where material accumulates can affect formwork and supporting structures. A crew must not change the plan simply because the pump is capable of delivering more. Today the key question is who controls the sequence and how every operator hears a stop instruction before the temporary works are overloaded.

Use the controls

Review the approved pour arrangement, including access, delivery positions, communications, and the conditions requiring a pause. The responsible qualified personnel establish structural and temporary-works limits; this talk does not provide a universal pour rate. Do not stack materials or concentrate wet concrete where the plan does not allow it. Keep the pump operator, placement crew, and person overseeing the forms connected through the agreed communication method.

Work within the safe plan

If placement cannot follow the plan because access changes or a crew falls behind, stop and obtain direction rather than inventing a new sequence. Report form movement, leakage patterns, or support changes from a safe location. Do not ask a worker to stand in a collapse path to watch more closely. After an interruption, confirm the revised instructions with everyone affected before restarting. A controlled pour is one in which stopping is immediate and understandable, even when several trucks and different employers are waiting.

Discuss with the crew

A truck delay is recovered by pumping into one wall section much faster than planned.

Question: Can the crew choose the new rate on its own?
Answer guidance: No. Obtain direction through the responsible technical and supervisory process.

Question: What should happen when operators cannot hear the stop signal?
Answer guidance: Pause placement until reliable communication is restored.

Prepare, act, and follow up

Leader preparation: Bring the approved placement sequence and communication plan.

Put it into practice: Rehearse one stop signal and repeat-back using the actual planned crew roles.

Supervisor follow-up: Verify the placement briefing and drawings agree before the pour starts.
