The challenge
Complex constraints.Real-world pressure.
Before architecture and implementation, we mapped every operational blocker and business risk. These were the core constraints shaping the entire solution design.
4 critical challenges
02Constraint
Paper surveys with no standard schema
03Constraint
Zero offline field data capture
04Constraint
Months behind schedule and over budget
What we built
A system built for the problem, not off the shelf.
We built a GIS-native survey application with a local-first architecture. All base maps, ward boundaries, and survey checklists were pre-loaded on the device. Field surveyors could capture asset location via GPS, complete type-specific forms, and photograph assets — all without connectivity.
A deterministic conflict-resolution protocol handled merged data from multiple surveyors covering overlapping areas. The sync engine compressed and prioritised data to minimise bandwidth on low-speed connections when uploading.
The central management dashboard allowed supervisors to monitor survey progress ward-by-ward, validate submissions, flag anomalies, and export data directly to GIS formats (GeoJSON, Shapefile) for integration with the utility's asset management systems.
Capabilities delivered
Every feature with a reason.
01
Offline-first GIS capture
Base maps, ward grids, and checklists pre-loaded. GPS asset capture, photo documentation, and form submission work with zero connectivity.
02
40+ asset type schemas
Custom structured forms for every utility asset type. Mandatory fields enforced locally — incomplete submissions cannot be finalised.
03
Deterministic offline sync
Conflict-resolution protocol handles multiple surveyors on overlapping zones. No duplicate records on merge.
04
Supervisor monitoring dashboard
Ward-level progress tracking, submission queue, anomaly flagging, and field team location visibility for supervisors.
05
GIS export
One-click export to GeoJSON and ESRI Shapefile for direct integration with existing GIS / asset management platforms.
06
Photo-to-asset linkage
Photos compressed and geo-tagged on device. Permanently linked to asset record — visible in both mobile and web interfaces.
