The phase-out of coal is coming. With it, a massive structural transformation process begins for the directly affected regions in Central Germany. Mine operators are planning to dismantle their facilities and renaturalize and repurpose the abandoned opencast mines. Cities and municipalities are developing concepts, and transfer companies are ensuring the socially acceptable transition of thousands of jobs. In the midst of these developments, Schneider Seidel is playing an important role in supporting local and regional planners. Let's get started!

Drone-based surveying is now a core service—rapid capture, lower risk, and survey-grade results. We operate RTK/PPK drones with rigorous ground control to acquire dense, consistent data on construction sites, industrial plants, corridors, and quarries. From photogrammetry and LiDAR we produce clean, well-registered point clouds and keep alignment tight across missions.

 

The real advantage is our after-processing. We classify clouds, remove noise and occlusions, and turn raw data into usable outputs: watertight meshes, DSM/DTM terrain, contours, breaklines, volumetrics, and true-scale orthomosaics. 

For CAD and BIM, we simplify geometry, enforce topology, and deliver DWG/DXF, LandXML, or IFC—accurately georeferenced to your coordinate system.

 

Quality controls are built in: automated checks, versioned change tracking, and clear metadata.

 

The result is reliable terrain and structure models that drop straight into design workflows for coordination and quantity takeoff. Typical use cases include progress monitoring, as-built documentation, earthworks tracking, stockpiles, corridor mapping, asset inspection, and pre-design feasibility.

this is how we do it


We rely on state-of-the-art technologies to deliver our projects with maximum efficiency and precision. A key element of our approach is the integration of our clients into a Common Data Environment (CDE). Through this platform, we receive, distribute, store, and securely archive all project data in a transparent and structured way.

For this, we use the highly powerful application Trimble® Connect™, which we license ourselves and provide to our clients. Its advanced functionality ensures seamless collaboration, data security, and transparency—critical factors for safeguarding project success and achieving outstanding results together.

When we look at our most successful projects, a clear pattern emerges: every single one of them was built on the foundation of a Common Data Environment (CDE). By centralizing all project information—drawings, models, documents, and communications—into one secure and structured platform, we enabled all stakeholders to collaborate with remarkable efficiency and clarity.


A CDE creates a single source of truth. It eliminates the confusion of multiple versions, ensures that everyone is always working on the latest data, and significantly reduces the risk of errors or costly rework. This clarity empowers teams to make decisions faster and with greater confidence, keeping projects on schedule and within budget.

With built-in version control, access management, and streamlined workflows, the CDE provides structure while remaining flexible to the unique needs of each project. It allows project participants to work simultaneously, knowing that their contributions are securely stored, transparently documented, and instantly available to others.

Ultimately, the use of a CDE has proven to be the key to stronger collaboration, higher productivity, and consistently successful outcomes. It is not just a tool— it is the heart of effective modern project delivery.


At Schneider Seidel, we harness cutting edge technologies — such as laser scanning for existing buildings and drone overflights for entire neighborhoods or digital terrain models — to deliver exceptionally precise point cloud data. By capturing millions of points in high resolution, we generate accurate three‑dimensional representations of structures and sites. These robust data sets can be seamlessly imported into any industry‑standard CAD software using plugins, enabling further modeling.

Whether you’re planning renovations, urban developments, or infrastructure projects, our workflow ensures maximum accuracy, efficiency, and compatibility. We bridge advanced surveying techniques with practical digital tools to streamline planning, visualization, and collaboration. Ultimately, our innovative approach provides architects, engineers, and planners with reliable, editable point‑cloud models to support informed decisions and high‑quality deliverables across every phase of your project.
