Water-Network As-Built Conversion Program
40 years of paper and CAD as-builts converted into a connected ArcGIS Utility Network model — 380,000 assets.
Where the client started
A water utility’s institutional memory was retiring: forty years of paper and CAD as-builts, interpreted daily by staff nearing retirement, with no connected network model behind the counter maps.
The OutcomeWhere they ended up
The utility went live district by district with 99.4% audited attribute accuracy. Institutional knowledge that lived in retiring heads is now a traceable network model every engineer can query.
How we delivered
Scanning, indexing and georeferencing of the full as-built archive
Feature capture into a Utility Network data model with pressurised topology and gravity inverts
Attribute population with double-key verification against source documents
Connectivity validation and subnetwork tracing before each district cutover
- Georeferenced as-built archive
- Connected Utility Network model
- 380k attributed network assets
- Validation & trace reports
- Cutover & training support
