Real sites. Lasting records.
A permanent record of what was evidenced on a site.
Parcel + photos + supporting evidence. A named reviewer approves. Residual publishes one verification page and PDF.
Built for teams that need a defensible handover record after ecological, environmental or site work.
Bound to a real site
Every record is tied to a parcel / AOI and the evidence supplied for that location.
Reviewed by a person
Nothing publishes until a named reviewer explicitly approves or rejects the record.
Proof of record integrity
Signed evidence commitments make later changes detectable and preserve the integrity of the issued record.
Why
Site evidence is often scattered across reports, emails, photo folders and project systems.
Residual creates one persistent record showing:
- Location
- Evidence supplied
- Named approval
- Issue date
- Current validity
How it works
01
Add the site
Bind a parcel / AOI so the record is tied to a place.
02
Attach evidence
Add site photos and any supporting evidence you already hold.
03
Reviewer decides
A named reviewer approves or rejects. Nothing publishes without a person.
04
Publish
Residual issues one public verification page and PDF.
