Coordinating a pour day across trades: the plan sheet, the hours and who is on the deck
The slab placement needs the concrete supplier, pump, finishers, testing personnel and several trades to align. The superintendent has a start time but no agreed contact for supply changes. An incomplete embed review could otherwise meet arriving trucks at the gate.
Use one coordination sheet to connect the reviewed placement plan with people, timing, access and communications. Confirm the prerequisite reviews and name who communicates supply adjustments. The sheet is not a concrete specification, pump setup design or guarantee of the finish time. WorkSafeBC identifies certificate requirements and equipment-type training for BC pump operations; qualified personnel must check the applicable arrangements rather than assuming a timetable authorizes equipment use.
Connect the placement plan to the day's interfaces
- Start with the approved planning basis. Confirm quantity, proposed supply rate and placement sequence with the responsible concrete personnel and supplier. Identify weather, access and other assumptions that need review. Do not infer a safe or suitable placement rate from a simple truck calculation.
- Confirm the prerequisite decisions. Link embed and sleeve reviews, inspections and the required release through their actual processes. Agree a practical coordination deadline for outstanding trade information. Record unresolved items and who decides the status; a previous-day meeting does not clear an incomplete hold point.
- Align people, access and services. Coordinate supplier arrivals, qualified pump personnel, testing attendance and finishing resources. Have appropriate people review equipment position, traffic, deck access and other safety arrangements. The coordinator records those decisions without designing the setup or selecting controls from convenience.
- Name communications and stop routes. Identify the routine supplier contact, their backup and who can authorize a rate change through the agreed plan. Keep emergency and safety reporting available to everyone through the proper process. One routine scheduling voice must not mean nobody else can raise an urgent concern.
- Brief, monitor and update the record. Share the current sheet with affected people and confirm material changes. Record actual arrivals, interruptions and responses on their proper basis. Refer changed conditions to the qualified decision-makers instead of protecting an original finish promise by continuing an unreviewed operation.
Common mistakes
- Treating a delivery-rate calculation as a safe placement plan.
- Confirming trucks while prerequisite reviews remain open.
- Using one supplier contact to suppress urgent reporting.

Check your understanding
The arithmetic shows eight-and-three-quarter supply hours. Does that establish when the slab will be finished?
