Surveying & Geomatics Services
As an Affiliate Member of The Survey Association (TSA), EDS has developed in-house geospatial capabilities to support both above- and below-water infrastructure projects.
Core Geospatial Offerings:
- Topographic Surveys – Using total stations, GNSS, and terrestrial laser scanning to produce detailed land and site surveys.
- Bathymetric Surveys – ROV-based and boat-mounted sonar surveys to chart water depths, bed profiles, and sediment layers.
- Multibeam & Sidescan Sonar – High-resolution underwater imaging to assess submerged structures, scour, debris, and environmental features.
- Structural Monitoring – Ongoing survey and inspection for movement, settlement, or deformation of critical infrastructure.
- Confined-Space Laser & Imaging Surveys – Delivering geospatial intelligence from areas inaccessible by traditional means.
- Point Cloud & BIM Integration – Capturing 3D spatial data for CAD modelling, BIM systems, and digital twin development.
- Survey Control Networks & Setting Out – Establishing control frameworks and providing high-accuracy positional data to guide construction phases.
Sectors Supported:
- Reservoirs, dams, culverts, and siphons
- Bridges, piers, jetties, and river walls
- Water treatment plants and outfalls
- Flood defence systems
- Quarries, marinas, and offshore structures
