What made this job notable

Extension mix and siting context in one pack

Three existing extensions were logged, increasing layout complexity for first-pass system planning.
Two ASHP location entries were recorded, including one with a documented 6m run to cylinder location context.
15 rooms and 4 floorplan captures required navigation that stayed usable for office and design teams.

What Vertex captured

Repeatable evidence layout across a complex semi-detached job

Layout context

Multi-zone room data structured around one consistent pack architecture.

Electrical baseline

Garage meter and consumer-unit context grouped with the rest of technical evidence.

Siting references

ASHP location records captured in the same workflow as floorplan references and room evidence.

Why structure matters

Extension-heavy properties punish generic survey exports

This job shows why Vertex positioning is system-led: the value comes from section logic and navigable evidence, not just collecting data. Teams could review extension context, ASHP siting notes, and electrical information without jumping between disconnected documents.

PlanUp reference 697148905 and 4 floorplan captures gave design and office teams one shared map of the job before install scheduling.

Installer takeaway

Structured packs reduce ambiguity on extension jobs

When layout history is mixed, standardised evidence grouping is what protects quote speed and handoff quality. This is where a purpose-built renewable survey workflow outperforms a simple form-to-PDF export.
