Reliable sewer data.
Precisely surveyed.
Intelligently processed.
HaDennis BV helps municipalities, contractors and engineering consultancies make sewer data complete, current and reliable. From inspection and as-built data to GNSS surveys and 3D LiDAR scans.
From source file to reliable asset data
Technology and sewer expertise in one workflow
Data is not merely processed, but assessed by a sewer specialist. Deviations, missing links and illogical geometry are identified before they affect management, maintenance or design.
Sewer data & inspections
Processing, checking, structuring and reliably linking inspection and asset data.
↗02As-built data
Correctly translating new and modified infrastructure into an up-to-date asset dataset.
↗03GPS/GNSS surveying
Precisely surveying manholes, pipes and objects in X, Y and Z.
↗043D LiDAR scanning
Digitally recording complex objects as point clouds, drawings and profiles.
↗05Quality control
Checking completeness, geometry, links and technical reliability.
↗Y 357.810,492
Z +42,318
3D scanning & surveying
Capture a location you can revisit later
Pumping stations, manholes and special structures are recorded digitally with precision. Back at the office, the site can be viewed, checked and measured again — without returning to the location.
- Georeferenced LAZ point cloud
- Plans, elevations and profiles
- Dimensions and levels
- DWG, DXF, PDF and visualisation
One coherent picture
Different sources. One usable result.
HaDennis combines existing asset data with inspections, as-built drawings, CAD, GIS and measurements to create a dataset professionals can build on.
