Engineering service
From shop drawings to a quoting-ready BOM
Send us your aluminium panel, curtain wall or ceiling shop drawings (DWG / DXF / PDF). We return a structured BOM, a QC inspection checklist and a change report — and we point out where the drawing itself is missing information before anyone prices it.
Why drawings stall quotes
The biggest obstacle is not the material — it is the drawing
In every shop-drawing review we run, five problems appear again and again. If your team has re-priced a job three times because the drawing changed or was wrong, this service was built for you.
Key dimensions missing
Panel thickness or fixings not stated on the drawing. A quote built on an assumed thickness is a quote that can be wrong.
Dimensions stated incorrectly
One wrong callout downstream of a cutting table becomes scrap.
Unit confusion
Mixed units across sheets, layers and notes — 3.0mm written as 3mm, or kPa where N/mm² belongs.
No unified part numbering
The same part carries a different code in the schedule, on the drawing and in the BOM — so nobody can reconcile them.
Quiet drawing changes
Revision B changes a spec on one detail drawing. Nobody flags it, and the price goes out the door stale.
The service
Four deliverables from one set of drawings
Structured BOM (takeoff)
Every entity in your DWG/DXF is parsed into a structured bill of materials — component, specification, quantity — delivered as a spreadsheet your estimating team can price line by line.
Version & change report (ECN)
Send us two revisions. We diff them element by element — geometry, specification, annotations — and flag every change that affects price: thickness, material, finish, colour, tolerance. One spec changed = the quote must be re-run. We make that visible.
QC inspection checklist
A 23-point inspection table with the critical-to-quality parameters marked, ready to run at inbound, in-process and outbound inspection — delivered as a working spreadsheet.
Unified part numbering
One code per component, stable across every drawing, schedule, BOM and revision — so the cutting list, the quality record and the invoice describe the same physical part.
Our working rule
What we can't read, we don't guess — we ask
Every output carries an “items to request” list: the fields that are not stated on your drawing — thickness, tolerance, finish, fixings — each flagged “not on drawing, please confirm” instead of silently filled in. A BOM with a hidden assumption is not a BOM; it is a risk. We would rather send you one list of questions than a quote that is quietly wrong.
How it works
Drawings in, three files out
Send the drawings
DWG, DXF or PDF shop drawings, plus the revision pair if you have one. No account, no upload platform to learn.
We parse and verify
The drawings are read entity by entity. Dimensions, blocks, annotations and layers are checked against each other; inconsistencies are logged, not silently corrected.
You receive the pack
A structured BOM spreadsheet, the QC inspection checklist, the change report where applicable — and the “items to request” list, so the next revision cycle starts clean.
Who this is for
Made for the aluminium shop-drawing workflow
Aluminium panel fabricators, curtain wall subcontractors and ceiling installers whose drawings come from AutoCAD or Rhino-based detailing — and anyone who has re-priced a job because a revision arrived quietly. Works across our product lines: ceiling systems, ACP sheet, unitised and stick curtain wall panels.
