# Construction Passports — your DoP and EPD, structured

> Turn your DoP and EN 15804 EPD into a CPR-compliant DPP. TracePass fills 48 construction-product fields with attachable evidence and a public viewer.

Upload your Declaration of Performance and EN 15804 EPD. TracePass structures them into 48 CPR-ready fields, hosts the PDFs as evidence, and publishes a per-batch passport you can QR-label at the factory gate.

## Who it's for

Manufacturers of insulation, windows, doors, plasterboard, concrete, structural steel, glazing, roofing, and sanitary products under harmonised technical specifications.

## How TracePass helps

- Attach your existing DoP PDF; we read it for essential-characteristics values and hold the PDF as evidence per field.
- EPD lookup from ECO Platform + manufacturer sustainability pages fills carbon footprint + lifecycle data automatically.
- Fire / reaction / VOC class as structured enum fields — not free text — so regulators parse them reliably.
- When your product doesn't have a manufacturer-specific EPD yet, we attach the category-default EPD with clear provenance so the passport is still compliant during transition.
- Batch-level passports (not per-item): one DPP per production batch with the batch number as serial. Matches how the industry already tracks.
- Field coverage mapped to the Construction Products Regulation (Regulation (EU) 2024/3110) Annex III — so every essential characteristic the regulation requires has a slot in the schema, not a free-text catch-all.

## What the template covers

- DoP + essential characteristics (per harmonised standard)
- Fire reaction + fire resistance class
- VOC emissions + dangerous-substance release
- Thermal / acoustic / mechanical performance
- EN 15804 EPD carbon footprint + lifecycle
- Recycled + bio-based content %
- Installation + maintenance URLs

## FAQ

### Most small manufacturers don't have EN 15804 EPDs yet. Can we still be compliant?

Yes. The template falls back to category-average EPD values (from ECO Platform) with explicit provenance in the evidence field. When your own EPD arrives, you replace the value and the audit trail records the upgrade.

### One passport per batch or per product family?

Per batch — that's how construction already tracks. Declaration-of-Performance numbers usually change per batch anyway. TracePass stores the batch number on each passport and the product-family metadata on the shared product record.

### Does the construction DPP replace our Declaration of Performance, or is it a separate thing we now have to maintain twice?

It doesn't replace the DoP — under the Construction Products Regulation (CPR, Reg (EU) 2024/3110) the DPP becomes the digital carrier that makes your DoP and EN 15804 EPD machine-readable and publicly accessible behind a GS1 Digital Link QR. TracePass reads your existing DoP and EPD once and structures them into the 48 CPR fields, so you maintain the source documents you already issue, not a second parallel dataset. When a value changes, you update it in one place and the published passport reflects it.

### If the AI fills our declared performance values from the DoP, who's accountable when a number is wrong?

You are — TracePass never publishes anything on its own. The AI proposes each of the 48 fields with a confidence score and a link back to the exact DoP or EN 15804 EPD page it pulled the value from, and nothing goes live until you review and approve it. That source attribution means your compliance reviewer can verify every declared performance value against the original document instead of trusting a black box, which is exactly the audit trail a CPR market-surveillance check expects.
