At 3D Scan BatAs part of our services, we carry out accurate terrestrial topographic surveys, tailored to the pre-project phases. Our surveys include contour lines, surrounding buildings, visible infrastructure and the site's major natural features.
Our 3D terrestrial laser scanning allows us to faithfully document the relief of the terrain and the surrounding volumes, and to deliver plans in DWG and PDF formata 3D model in REVIT or ARCHICAD in RVT - PLA or IFC format, as well as an point cloud in .e57 format or an online virtual tour.
This technology also offers a decisive advantage: the possibility of simultaneously capture the terrain and its immediate context with great precision. The surveys include not only elevations, but also the visual details needed to understand the site, such as facade alignments, paved areas and street furniture. This wealth of information makes it possible to carry out more detailed analyses and produce realistic renderings, which are useful for project presentations or applications for permission from the local authorities.
Requirements for a good topographic survey
To ensure optimum model accuracy:
- The grass must be cut flush with the ground before lifting.
- Dense wooded areas cannot be scanned (lack of visibility for the scanner).
- Isolated trees are represented as volumes as observed on the day of the scan.
- Undergrowth and opaque areas are not included in the survey.
Property boundaries and georeferencing
We propose two options for integrating property boundaries:
- Superimposing the point cloud on the cadastral map quick method but non contractualthen the limits are indicative.
- Precise geo-referencing based on coordinate points supplied by a surveyor A more reliable solution, suitable for projects requiring a legal basis or exact anchoring to the LV95 system.
⚠️ Please note: unless specifically requested, our surveys are not georeferenced or altimetric. The reference level can be defined arbitrarily, for example at the bottom of the plot (level ±0.00).
The choice between a simple cadastral overlay and precise georeferencing depends on the project objective and the level of accuracy required. For a preliminary project or a sketch, an indicative positioning is generally sufficient. However, for technical studies, permit applications or works subject to strict legal constraints, the LV95 georeferencing becomes essential. We work in collaboration with surveyors to incorporate reliable control points, ensuring perfect compatibility with official data and an exact match with the terrain.
A complete deliverable for your topography projects
Our deliverables for your standard architectural plans include :
- Topographical plans with contour lines every 1 metre
- Orthophoto of the site superimposed on the topography
- Point cloud (.e57) ready for CAD software
- 3D virtual tour (via ATIS-CLOUD link)
- Simplified modelling of existing buildings (LOG 200/LOG 300 as required)
- Site contextualisation: modelling of visible features around the plot (adjacent buildings, roads, walls, infrastructure)
Integration of topographic surveys in BIM
The integration of accurate topographic surveys into a BIM (Building Information Modeling) process makes it possible toimprove project coordination. Our data is supplied in formats that are compatible with the main BIM platforms, making it easier to model the land and integrate it into the overall digital model. This approach reduces design errors, improves communication between architects, engineers and clients, and enables the impact of developments on the site to be simulated more accurately. Surveys can also be enhanced with environmental or technical data for long-term use.
For which projects?
Our readings are particularly suitable for :
- New build or extension projects
- Landscape and architectural integration studies
- Town planning, area development or PPE projects
- Coordination meetings between architects, landscape architects, engineers or authorities
A solid basis for your preliminary projects
We favour useful topography right from the sketch phase, rather than a pure engineering survey. Our plans are designed to provide the architect or project owner with a reliable, legible and structured support that facilitates decision-making.
Surveys adapted to sensitive areas and environmental constraints
Some sites require a specific approach due to environmental, heritage or technical constraints. Our teams know how to work in areas that are difficult to access or subject to regulations, while complying with safety protocols and legal obligations. For protected natural areas, we favour low-impact survey methodswhile guaranteeing the accuracy of the data. This expertise enables us to provide reliable deliverables, even for projects subject to validation by environmental or heritage authorities, where accuracy and documentary conformity are crucial.
