Networks under the city
Utilities
Water, power, telecom and drainage share the same crowded ground. SEC works with utility owners and contractors to survey their networks and hold the results as structured asset data.
Sector challenges
The cost of invisible networks
Records that don't match the ground
Legacy drawings and tribal knowledge standing in for structured network documentation.
Third-party damage
Every unrecorded line is a strike waiting for the next excavation permit.
Expansion through congestion
New feeders and mains threading through corridors already full of other owners' assets.
Asset data locked in paper
Operations and maintenance decisions made without a queryable digital picture of the network.
Project lifecycle
From detection to living asset data
01
Records review & scoping
Existing documentation compiled and gaps identified before fieldwork.
02
Underground detection
Electromagnetic locating and GPR survey across the survey area.
- Underground & Subsurface Detection
- GPR Survey
- Utility Detection & Locating
03
Survey & positioning
Detected alignments and surface assets positioned by GNSS on the project datum.
- GNSS / RTK Survey
- CORS Network & RTK Services
04
Corridor mapping
Topographic and aerial capture of network corridors for extension and rehabilitation design.
- Topographic Survey
- UAV & Aerial Survey
05
GIS asset data
Networks structured into attributed GIS layers — location, type, condition and connectivity.
- GIS & Geospatial Solutions
- Asset Mapping
06
Construction support
Setting-out and survey control for new lines, diversions and rehabilitation works.
- Construction Survey
07
As-built data capture
New assets surveyed at installation — into the GIS before the trench closes.
- Engineering Survey
- GIS & Geospatial Solutions
Technology approach
From signal to record
Complementary methods
Electromagnetic locating and ground-penetrating radar are scoped together where a survey area calls for more than one method.
Positioned, not sketched
Detected alignments are surveyed onto the network datum and delivered as structured mapping.
GIS as the operating picture
Web GIS puts the same network picture in front of planning, operations and field crews.
Field equipment
CHCNAV
CHCNAV i50 GNSS
A GNSS receiver referenced across SEC's earlier project records.
Radiodetection
