Bathymetric Surveying
Measures water depth and maps submerged terrain using single-beam and multibeam sonar for rivers, lakes, reservoirs, channels, navigation routes, and other project areas.
Dredge Surveys & Monitoring
Provides pre-dredge, progress, and post-dredge surveys to establish existing conditions, track work, and verify completed depths, elevations, and changes to the underwater surface.
Integrated 3D Mapping
Multibeam & Vessel-Based LiDar
Combines underwater sonar mapping with above-water laser scanning to develop coordinated 3D information for shorelines, bridges, dams, banks, navigation areas, and other built environments.
Underwater Infrastructure & Structural Surveys
Maps submerged and partially submerged infrastructure such as bridge pilings, dam components, intakes, foundations, and related structures, including bed-condition and scour assessment.
Underwater Inspection & Imaging
Uses ROVs, side scan sonar, and imaging sonar to locate, inspect, and document underwater objects or structures where visibility, access, or working conditions are limited.
Sediment & Subsurface Investigation
Uses sub-bottom profiling to investigate layers beneath the bed and core sampling to recover physical sediment for examination, characterization, or project-specific testing.
f.a.q.
You have questions. wE have answers.
Understanding your project starts with understanding what’s possible. From the surface to the subsurface, we help make the unknown measurable.
AESI supports hydrographic, geospatial, infrastructure, environmental, construction, industrial, and resource-sector projects across a wide range of site conditions.
Our services can support a wide range of clients including federal, provincial, and municipal governments, First Nations and Indigenous organizations, engineering and environmental consultants, contractors, utilities, resource and industrial operators, and other private-sector organizations.
YES — Our capabilities span both environments and include hydrographic surveying, LiDAR, UAV photogrammetry, laser scanning, mobile mapping, ROV inspection, and other geospatial technologies.
We consider project objectives, site conditions, water depth, accessibility, required accuracy, coverage, and final deliverables to determine the most appropriate technology or combination of technologies.
Yes, where suitable. Existing survey data, CAD files, GIS information, imagery, previous surfaces, and other project records can often be incorporated to support comparison, planning, monitoring, or continued project development.
Yes. Combining technologies can provide a more complete understanding of a site. Sonar, LiDAR, UAV imagery, laser scanning, and other survey methods can be integrated to capture both submerged and above-water features within a coordinated dataset.
Single-beam sonar measures depth directly beneath the survey vessel along individual survey lines. Multibeam sonar captures a much wider area of the bottom, providing greater coverage and detail. The appropriate method depends on the project scope, site conditions, and required level of detail.
THE NEXT STEP STARTS HERE.
Bring us the project, the challenge, or the question that needs answering. Whether you’re planning something new or addressing conditions in the field, AESI can help define the right approach and move the work forward.
