Specvo
Private beta for UK OCDEAs

Drawings and spec in — Elmhurst-ready SAP XML out.

Specvo reads UK planning PDFs, DWGs and specifications, then produces a ready-to-review SAP 10.2 XML that imports directly into Elmhurst. You keep the judgement. We drop the measuring.

Built on how OCDEAs actually work

SAP assessors lose hours to measuring and chasing developers for missing details. Specvo does both — and hands the file back with every gap flagged.

Vector-first extraction

80% of UK planning PDFs have extractable vector geometry. We read rooms, walls and openings to the millimetre — not pixel guesses.

Catches missing details before you run

Three tiers: hard blockers, SAP defaults, and quality improvements. Each missing item gets an auto-drafted email back to the client.

XML that Elmhurst accepts

Value-level equivalence with Elmhurst Design SAP 10. Import the XML, review, submit — our generated file is round-trip validated.
