# Precast concrete software that ties every piece to its pour, its cylinder break and the truck it left on

> Precast concrete production is the factory casting of concrete pieces in reusable forms off site, cured, stripped, stored in the yard and shipped to an erector who lifts them into place. The strength record follows it the whole way. Portland's manufacturing standard holds forms on wet cast concrete until the mix reaches 2,500 psi on field cured cylinders, and OSHA requires lifting inserts on non tilt up precast members to support at least four times the maximum intended load. Neurobird holds the piece, the pour, the break results and the load on one record.

## What Neurobird Precast Concrete Production does

- Tie each piece to its pour and to the cylinders cast from the same concrete
- Hold strip strength and shipping strength as recorded results, not as a supervisor's judgement
- Track pieces in the yard by mark number and by the load they are promised to
- Keep insert ratings and handling limits on the piece, where the rigger can actually read them

## How it works

1. **Cast against a record** The piece carries its mark number, mix design, pour date and the cylinder set taken from the same concrete, so strength is never attributed to the wrong batch.
2. **Strip and store on results** Forms come off against a recorded break rather than a shift pattern, and the piece moves to a yard location that the load list can find again.
3. **Load to the sequence** Shipping strength, insert ratings and the erector's sequence position travel with the piece, so what arrives on site matches what the crane was planned around.

## Industry context

- **4 times** Load factor a lifting insert embedded in a precast member other than a tilt up member must support, against the maximum intended load applied or transmitted to it. (source: OSHA 29 CFR 1926.704, https://www.osha.gov/laws-regs/regulations/standardnumber/1926/1926.704)
- **5 times** Load factor required of the lifting hardware itself, while inserts in tilt up members must carry at least two times the maximum intended load. (source: OSHA 29 CFR 1926.704, https://www.osha.gov/laws-regs/regulations/standardnumber/1926/1926.704)
- **2,500 psi** Compressive strength, on field cured cylinders held under the most severe conditions the product will see, before forms on wet cast concrete may be removed. (source: City of Portland, manufacturing standards for precast concrete products, https://www.portland.gov/bes/documents/manufacturing-standards-precast-concrete-products/download)
- **100 cubic yards** Sampling rate for a minimum of three 28 day test cylinders, or once every week of production, whichever is greater, with a cylinder discarded if it varies by more than 10 percent from the average of the other two. (source: City of Portland, manufacturing standards for precast concrete products, https://www.portland.gov/bes/documents/manufacturing-standards-precast-concrete-products/download)
- **500 psi** Compressive strength below which a precast product that freezes is rejected outright rather than assessed. (source: City of Portland, manufacturing standards for precast concrete products, https://www.portland.gov/bes/documents/manufacturing-standards-precast-concrete-products/download)
- **637.209** The federal highway rule that keeps a non state laboratory to one role per project, so verification, quality control, independent assurance and dispute testing cannot be done by the same lab. (source: 23 CFR 637.209, https://www.law.cornell.edu/cfr/text/23/637.209)

## Questions

### What is precast concrete production?

It is factory casting of concrete pieces in reusable forms, cured and stored at the plant and shipped to site for erection. Because the piece is finished before it arrives, the strength and handling record has to travel with it, which is why cylinder results and insert ratings matter as much as the shape.

### What are the lifting rules for precast pieces?

OSHA 29 CFR 1926.704 requires lifting inserts in tilt up members to support at least two times the maximum intended load, inserts in other precast members at least four times, and the lifting hardware itself at least five times. Only employees required for erection may be under a piece being lifted.

### Does this replace our batch plant system?

No. It sits beside it. The batch system owns the mix and the ticket. This holds the piece: which pour it came from, which cylinders belong to it, when it was strong enough to strip and ship, and which load it went out on.

### How does it handle cylinder testing?

Cylinders are recorded as a set tied to the concrete they were cast from, so the strip decision and the shipping strength decision each point at a result rather than at a date. Sampling rates like three cylinders per 100 cubic yards are set per customer standard.

### Can an erector see the sequence position?

Yes. Each piece carries its mark number, shipping strength confirmation and its place in the erection sequence, so the yard loads to the crane plan instead of to whatever is nearest the gate.
