Key Findings
- Ticket time, batch volume, mix identification, admixtures, slump notes, and water additions can matter if the slab later has performance questions.
- The ticket should be reviewed before discharge begins, because the wrong mix or quantity is harder to resolve once concrete is in the forms.
- Signatures and handwritten changes should be treated as project records, not casual paperwork.
Why the Ticket Matters
A concrete delivery ticket is not a quality guarantee by itself. It is a record of what the supplier says was batched, when the truck was loaded, how much concrete was delivered, where it was sent, and what adjustments were recorded. If the owner later asks why a driveway scaled, why a slab cracked early, why a finish dusted, or why the order ran short, the ticket is one of the first documents that can narrow the review.
The most useful time to read the ticket is when the truck arrives. A mismatch in job address, quantity, strength class, air entrainment, slump range, aggregate size, fiber, accelerator, retarder, or color should be caught before discharge. The crew may be busy with forms and placement, but one person should be responsible for checking the ticket against the order and saving a readable copy.
Ticket Fields to Read
| Field | Why it matters | Owner-side check |
|---|---|---|
| Batch and arrival time | Long haul or waiting time can affect slump, finishing window, and dispute records. | Record arrival, discharge start, discharge finish, and any waiting cause. |
| Quantity | The truck volume should match the ordered yardage and placement sequence. | Compare ticket quantity with the takeoff and any planned waste allowance. |
| Mix designation | Strength, air entrainment, aggregate, admixtures, and exposure assumptions may be embedded in the mix code. | Ask the supplier or contractor to translate the mix code before discharge if unclear. |
| Slump and water notes | Water added at the site can affect workability records and may affect performance if it exceeds allowed limits. | Write down who requested water, how much was added, and whether it stayed within the approved range. |
| Admixtures and fibers | Accelerators, retarders, air entrainment, water reducers, color, and fibers can change behavior and finishing. | Confirm the ticket matches the quote and the placement conditions. |
Red Flags Before Discharge
A ticket deserves immediate attention when it shows the wrong address, wrong customer, wrong quantity, unexpected mix code, missing air entrainment for exterior freeze-thaw work, missing fiber where it was ordered, an unexplained accelerator or retarder, excessive time since batching, or water already added without a record. Not every difference means the load must be rejected, but every difference should be resolved by someone with authority before the concrete is placed.
Handwritten changes are especially important. They may be completely legitimate, such as a documented water adjustment within the allowed range. They may also be the only clue that the truck was delayed, the slump was changed, or the field team accepted a different condition than the original quote. A photo of the ticket and a short pour log can prevent a later argument from depending on memory.
What to Keep in the Owner File
- Readable photo or scan of every delivery ticket, including handwritten notes and signatures.
- Ordered quantity, actual delivered quantity, and where each truck was placed when there are multiple loads.
- Truck arrival, discharge start, discharge finish, finishing start, curing start, and saw-cut start where applicable.
- Weather notes: temperature, sun, wind, rain threat, and whether the slab was shaded or exposed.
- Photos before discharge, during placement, after finishing, after curing setup, and after joints are cut.
Method Note
This document review is based on common ready-mix delivery documentation practices, concrete placement references, and field troubleshooting categories. Ticket formats vary by supplier, plant software, region, and project type, so the field names may not appear in the same order on every ticket.
Practical Implication
The delivery ticket is useful because it is contemporaneous. It captures facts at the moment decisions are made. Reading it before discharge and saving it after placement gives the owner a better record than a receipt alone.
