Before the ready-mix concrete truck rolls up, make sure your forms are solid, clean, and coated with release agent, the subgrade is prepped and compacted, and you have a clear, obstruction-free path for the truck to reach the pour site. Also confirm the weather forecast — extreme heat, cold, or rain can mess with the concrete's set time. Finally, check that you have enough workers and tools on hand to place and finish the concrete before it starts to harden.
