23As a special demonstration, the Pirate Village was captured in three dimensions using LiDAR with an integrated camera. The camera added the actual colours to the measured points, creating a recognisable, colourised 3D point cloud of the temporary village.
22A visual project presentation brings the entire workflow together: mobile LiDAR capture, point clouds, dimensions, BIM models and before-and-after comparisons. The video shows how raw scan data is transformed into practical information for asset management.
21Overflows, stormwater settling basins and pumping stations are converted from current LiDAR scans into structured digital 3D models. Scan-to-BIM gives asset managers a practical, up-to-date view of complex structures and supports safer, more efficient management.
20A dry-installed wastewater pumping station was fully scanned with LiDAR and developed into a digital BIM model. The workflow connects the actual existing condition to a structured 3D model for asset management, renovation and technical coordination.
19No usable drawings were available for a stormwater settling basin beneath a wooded area. Mobile LiDAR was used to capture the complete structure. A longitudinal section was subsequently produced from the same scan for asset management and technical preparation.
18A multifunctional space with both above-ground and underground components was captured in three dimensions. The scan clearly shows the relationship between the playground and the water storage system beneath it.
17A timber bridge without usable existing drawings required an accurate digital survey at short notice after wood decay was identified. 3D scanning captured its current condition as a basis for assessment and further technical development.
16To prepare the Maastricht-West sewer data for hydraulic modelling, current information on special structures was collected and verified. Targeted 3D scans and technical data checks filled gaps and resolved uncertain attributes, creating a more reliable hydraulic model.
15A historic grain mill dating from 1879 was fully captured as a three-dimensional point cloud. The scan documents its current condition and enables accurate measurements and virtual inspection without affecting the character of the listed structure.
14Several individual LiDAR scans of sewer structures were combined into one coherent digital model. This creates a more complete spatial view and makes it easier to compare and measure the different components.
13HaDennis delivered a practical demonstration of mobile 3D scanning for Geo, Data and Design students. Participants saw how a physical environment is captured, processed into a point cloud and then used for measurements and visualisations.
12Scans of an overflow manhole, vortex flow control, stormwater settling basin and surrounding storage basins were combined into a single integrated site model. This shows both the individual structures and their spatial and functional relationship within one environment.
11Several overflows and a pumping station with an integrated overflow were captured accurately. The acquired geometry provides an up-to-date view of these special structures and a practical basis for preparation, analysis and asset management.
10HaDennis and the Municipality of Maastricht developed a method for capturing special sewer structures quickly and accurately without entering them. Mobile LiDAR and SLAM produce practical 3D models for asset management and analysis. The project won the 2023 RIONED Innovation Award.
09A hard-to-reach overflow manhole in a rural area was captured using mobile LiDAR. The method enabled fast and complete data acquisition despite its position beside a stream and the limited accessibility of the structure.
08An underground basin was fully captured in three dimensions. The scan reveals the internal structure from new perspectives and gives asset managers better spatial insight than a traditional two-dimensional drawing alone.
07A complete underground stormwater settling basin was surveyed using mobile LiDAR. The three-dimensional capture makes the structure visible from every viewing angle and provides a durable digital basis for asset management and future work.
06Scan data was used to clarify the relative positions and likely operation of components in an unclear sewer configuration. The visual reconstruction helped verify existing data and improve understanding of the situation.
05An underground stormwater settling basin was fully captured in a short time using mobile LiDAR. The point cloud provides an accurate and clear view of the structure and supports asset management, inspection and further technical development.
04A complex overflow structure was captured from ground level in just a few minutes using mobile LiDAR. The scan revealed its construction and operation without requiring entry. Dimensions and a technical cross-section could later be derived from the same point cloud.
03Dead-end passages in an underground marl cave system were captured using mobile LiDAR. The scan provides a coherent three-dimensional view of an environment that would be difficult and time-consuming to survey using traditional methods.
02A lined retention basin and a water authority basin were fully captured in three dimensions using mobile LiDAR. The point cloud makes it possible to determine their shape, dimensions and capacity digitally afterwards, without having to measure every point manually.
01HaDennis reviewed, updated and clearly consolidated the existing sewer data. Missing information was added where possible, while outdated or conflicting data was corrected. This gives the municipality more reliable information for day-to-day sewer management, the Basic Sewerage Plan (BRP) and future work on the sewer network. The shapes and dimensions of special sewer structures were also added to the map, making their construction and function within the network easier to understand.
