How We Deliver: Methodology, Technology & Operational Rigour
Our three-pillar operational framework combining mobile AppSheet data capture, mandatory 18-point GPS photo audits, and senior surveyor QA desks.
A Standardised, Repeatable Survey Production Pipeline
High-volume surveying contracts fail when data collection is inconsistent across surveyors or when QA occurs weeks after field visits. Strata operates a rigorous, automated delivery workflow designed to catch exceptions on the day of inspection.
Field Capture (WI01)
Every surveyor operates under our WI01 v14 Field Work Instruction. The mobile app enforces taking mandatory, geotagged, and timestamped photos across 18 distinct property categories before a job can be marked as complete.
Same-Day QA Audit Desk
All submitted survey data, floorplan measurements, and photographic evidence are audited daily by our central technical QA desk. Any discrepancies trigger same-day re-checking before lodgement.
Live Client SPMS Sync
Completed surveys, official EPC RRN numbers, and structured asset condition CSVs/XMLs automatically synchronize with the client portal, providing 100% transparency on programme velocity.
Mandatory 18-Point Photographic Evidence Checklist
