Across many NHS estates, critical system information still lives in hand‑drawn sketches pinned to plantroom walls or carried around in engineers’ notebooks. One Hospital Estate's provided exactly that — quick, practical sketches photographed on a phone, capturing the live steam and condensate arrangements as they actually operate day‑to‑day.

These images formed the basis for accurate, modern CAD schematics. Each photo was interpreted, redrawn, and standardised into a clean, NHS‑aligned drawing with consistent symbols, clear isolation points, and proper layering. The result is a reliable technical record that reflects the real installation, not outdated legacy drawings.

Updating schematics in this way strengthens Estates operations: teams work from current information, shutdowns and isolations become safer, and future refurbishment planning is far more efficient. Whether your estate has photographed sketches, marked‑up PDFs, or legacy diagrams, converting them into professional CAD drawings (A3 size) ensures your technical documentation is clear, consistent, and fit for purpose.
