What constitutes proper signage and identification for a ready-mixed concrete delivery at a job site?

• A. Delivery ticket or mix design information visible, contractor and project number, strength/class, slump, air content, temperature, and batch time.
• B. Only the driver’s name.
• C. Color of the truck.
• D. The weather forecast.

Answer: (A)

Signage and identification on a ready-mixed concrete delivery focus on traceability and confirming the delivered material meets project requirements. A visible delivery ticket or mix design information should be displayed along with the contractor and project number, and the concrete’s strength/class, slump, air content, temperature, and batch time. This collection of details lets inspectors verify that the exact specified mix was produced, track it to the correct project, and confirm its properties are within acceptable placement and curing limits. It also supports quality control by showing when the batch was made and under what conditions it was delivered.

Other items like just the driver’s name, the truck color, or the weather forecast don’t provide the required information to verify the concrete’s composition, properties, and project association, so they don’t fulfill the signage and identification needs.
