For cast-in anchor plates in precast concrete, the purchasing handover should preserve the connection between an approved detail, a part mark and the items delivered. A box labelled “embed plates” is not enough to tell the receiving team which panel, revision or orientation those parts belong to.
This guide starts after the project design exists. It provides an original document-and-identification checklist for the precast buyer, not anchor selection, connection design or a substitute for the project’s inspection plan.
Build a mark-to-drawing cross-reference
Use the project’s existing part marks; do not create a second naming system in the purchase order. For each mark, record the approved drawing number and revision, the related panel or location reference, and the quantity for the release being purchased. Keep the approval record with the drawing package.
There is a useful manufacturer example in Leviat’s Tilt-Up Technical Manual, printed page 19: its sample shop drawing includes a panel number, revisions, face orientation and an embed schedule linking marks to details and counts. It is a tilt-up example, not a universal precast specification; the checklist below is our own purchasing adaptation.
| Link to preserve | Record with the order | Question to resolve |
|---|---|---|
| Mark → approved detail | Part mark, drawing number, revision and approval reference | Does the drawing in the quote match the released revision? |
| Mark → panel/location | Panel mark or location schedule, where the project requires it | Is the same plate mark used in more than one delivery release? |
| Detail → orientation | Named face, viewing direction and the project’s orientation reference | What does “left”, “top” or “front” refer to on this drawing? |
| Mark → delivery state | Plate only or listed assembly, attached parts, loose items and finish | Which items arrive together, and which are supplied elsewhere? |
| Mark → package | Package ID, marks, quantities and release reference | Can receiving staff locate each mark without guessing from its shape? |
Resolve orientation before making labels
A label cannot repair an ambiguous drawing. If two similar parts are mirrored, ask the project drawing owner whether they require separate marks. If orientation matters, carry the drawing’s named face and direction into the identification instruction. Do not invent an “up” arrow without a reference view.
Agree the marking method and location before fabrication. Ask how the identification will remain readable through the specified finishing, packaging and handling sequence, without affecting surfaces that the approved detail reserves for another purpose. This is a question for the agreed process, not a recommendation to stamp, weld or paint every plate.
Name the owner of each handover
For each mark, ask the quotation to identify who supplies the cut plate, who provides and attaches the specified anchors or other parts, who arranges the finish, and who supplies the agreed inspection records. Record exclusions alongside inclusions. A plate-only delivery and an attached assembly should not share an unexplained price line.
JSW’s embed request guidance separately asks for plate and anchor information, marks and quantities, and delivery needs, including phased releases. This supports separating those inputs; it does not establish what Zemlaser or another supplier can provide.
For a phased precast programme, distinguish total project quantity from this release quantity. A changed drawing should trigger a written check of affected marks, work already made and packages already identified. Ask for a clear disposition before mixing revisions into a release.
Use a receiving record that leaves room for a hold
The following is a blank record structure to adapt to the project’s approved quality plan. It is not a test method or an acceptance standard.
- Identity: order/release, package ID, part mark, drawing and revision, received quantity.
- Comparison: marking and orientation reference; specified attached and loose items; required document references.
- Checks: record the agreed dimensions, finish observations or other inspections against their specified criteria and report references.
- Disposition: accepted, held or rejected under the project procedure; discrepancy reference, reviewer and date.
Keep “count received” separate from “accepted for use.” A legible label does not prove material identity, weld quality or anchorage performance. If a mark, revision, orientation or included item does not match, identify and segregate the affected items under the project’s procedure while the responsible parties resolve the discrepancy.
Do not improvise replacement anchors, move attachments or change an approved detail to clear a receiving discrepancy. Structural loads, anchor configuration and design changes remain matters for the project’s qualified design authority.
Send a package the receiving team can use
Prepare the approved drawings and mark schedule, quantities by release, material and surface requirements, required records and arrival date. Include any unresolved orientation question before the order is agreed. Use the Zemlaser enquiry email to ask whether the specified supply scope can be provided and how to send the files. Confirm the fabrication, finishing and documentation responsibilities in the written offer.
