CAFM Drawings

We specialize in creating precise layout drawings of buildings and premises based on laser scanning data (point clouds), specifically optimized for seamless integration into Computer-Aided Facility Management (CAFM) systems. Every object on the drawing – a room, zone, or engineering element – receives a unique identifier and a set of attributes: precise area (usable, gross floor area, according to DIN 277), height, purpose, finishing materials. All information is structured into logical tables and semantic layers, strictly adhering to the logic and requirements of the target CAFM system.

We fully comply with CAFM documentation standards, including clear rules for area calculations (GFA, NFA, RM according to DIN 277) and numbering. Work is carried out in CAD environments applying strict discipline regarding layer structure, blocks, text and annotation styles, which ensures data integrity. The final drawings are fully adapted to the interface of the client's specific platform and are ready for immediate import without additional processing.

2D Architectural Drawings

2D Architectural Drawings are a set of technical drawings that convey all essential information about a building or structure in a standardized graphical form. They include a complete package of floor plans, elevations, architectural sections, and details required to accurately communicate the geometry of the assets. These drawings form the basis for developing design documentation, for expert review of the design documentation, for precise coordination between different project disciplines, and for the direct execution of construction works in compliance with applicable regulations.

We work in accordance with the stringent requirements of current European standards (DIN, ISO) and applicable regulations (e.g., HOAI), while adapting to the client’s internal standards. This ensures that the drawings are fully prepared for seamless import into any design, engineering, or asset management (CAFM) environment.

Digital Terrain Model (DTM)

A Digital Terrain Model (DTM) is an accurate three-dimensional mathematical representation of the Earth’s topographic surface, created by interpolating geospatial data—such as laser-scanning point clouds, aerial photogrammetric measurements, or geodetic survey data. To build the model, we use a Triangulated Irregular Network (TIN), which is well suited to representing complex terrain while maintaining elevation accuracy even in areas with abrupt changes.

During processing, we analyze and integrate data from multiple sources (e.g., laser scanning and total station measurements), and perform point classification to clearly separate the terrain (bare earth/ground) from artifacts, buildings, vegetation, and other above-ground objects.

The finished model serves as a universal geospatial baseline. We adapt its structure and coordinate reference system for seamless integration into your BIM workflows or CAD projects, and provide export in the required industry formats (*.xml, *.dxf, *.ifc, etc.).

Topographic Plans (Site Plans)

A Topographic Plan is a fundamental deliverable of engineering surveys, providing a detailed record of the planimetric and vertical position of all site features. It accurately represents the terrain, the location of buildings and structures, the routing of above-ground and underground utility networks, road infrastructure elements, land parcel boundaries, as well as vegetation and hydrographic features.

Such a plan serves as the mandatory geodetic baseline for developing design documentation, performing precise engineering calculations, supporting urban planning, and obtaining approvals from public authorities.

To produce topographic plans, we integrate data from multiple high-accuracy sources: laser scanning results, tachymetric surveys, GNSS measurements, and aerial photogrammetry products. This enables generation of topographic plans across scales—from 1:100 for highly detailed sites up to 1:25,000 for territorial planning—while maintaining survey-grade metric accuracy.

All deliverables are fully aligned with applicable national standards or international norms (DIN, ISO). Final outputs are supplied in a production-ready form and integrate seamlessly into CAD and GIS environments.

Cross Sections

Cross Sections are vertical slices of the terrain created perpendicular to the object’s centerline/alignment (road, route/corridor, canal, utility line). They clearly illustrate elevation changes and the configuration of the ground surface at defined intervals, and serve as a key basis for calculating earthwork quantities, performing engineering analyses, and developing design documentation.

Cross sections are generated from accurate geospatial data: laser-scanning point clouds, a Digital Terrain Model (DTM), or geodetic survey measurements. Where required, we compare the existing (as-is) surface against the design (planned) surface.

The deliverable is a drawing set in standard formats (DWG, DXF, or PDF), prepared in accordance with applicable national and European requirements.

Stereo Analysis

Stereo Analysis is a high-precision method of manual 3D interpretation and feature digitizing based on aerial photogrammetric stereopairs. The workflow enables reconstruction of the spatial position and shape of objects with photogrammetric accuracy, producing detailed vector datasets, digital terrain models, and precise geometric parameters.

This method is a standard in domains where spatial accuracy is critical: land cadastre, urban planning, territorial monitoring, infrastructure inventory, and the creation of a topographic/cartographic baseline.

Performing the work in specialized professional environments (e.g., Summit Evolution or Digitals) ensures maximum detail, accuracy, and ergonomics of the digitizing process by providing a full stereoscopic effect. Output vector data are clearly structured and referenced to the coordinate reference system, enabling direct use in GIS, CAD, and BIM systems (e.g., .dxf, .dwg, .shp) without additional conversion or correction.
