Engineering Geodesy in Sofia
Comprehensive geodetic support for engineering and construction projects of Category I and II — from source data and design to Act 16 and operation.
What's included
- ✓ Geodesy for tunnels, motorways, bridges, water/sewer
- ✓ Support of Category I and II construction projects
- ✓ Execution control and geometric monitoring
- ✓ As-built drawings and BIM models
What engineering geodesy is
Classical geodesy measures and documents the Earth’s surface; engineering geodesy applies this knowledge to realize engineering and construction projects. It is the “eyes” of the construction process — it transfers design solutions from paper to the field and verifies that actual execution matches the project.
Without quality engineering geodesy:
- A motorway may deviate from its alignment by meters;
- A tunnel may not meet correctly with the opposite bore;
- A building may be too close to a regulation line;
- Deformations in a dam wall or bridge may go unnoticed.
Project types we serve
Transport infrastructure
- Motorways and republican roads; tunnels — reference networks, bore offsetting, cross-section control;
- Bridges and viaducts — deformation monitoring; rail infrastructure.
Water and sewerage (V&K)
- New construction and rehabilitation of water and sewer; treatment plants; pump stations.
Buildings and complexes
- Residential and public buildings — survey, staking, control, Act 16;
- Industrial — halls, warehouses, technological lines;
- Reconstruction of historic buildings with 3D laser scanning.
Stages of our work
- Source data — establishing reference geodetic network, terrain survey;
- Design geodesy — drawings for the working project, longitudinal and cross-sectional profiles;
- Staking — transfer of design points;
- Execution control — periodic survey and comparison with design;
- Geometric monitoring — for objects with high requirements (dams, bridges, tall buildings);
- As-built documentation — drawings, BIM, certification documentation.

Frequently asked questions
What does engineering geodesy include?
Engineering geodesy is applied geodesy in construction and infrastructure. It includes establishing a reference geodetic network, source data for design, staking out design solutions, real-time execution control, deformation monitoring, as-built documentation, and geodetic support through Act 16 and beyond.
What kind of projects has your team executed?
Our team works on nationally significant projects — Zheleznitsa Tunnel (Struma Motorway), Hemus Motorway Lots 2 and 3, Krichim water rehabilitation, treatment plants, industrial and public buildings.
Do you work with BIM models?
Yes. We have 3D laser scanners and software for processing point clouds into BIM models (Autodesk ReCap, Revit). We deliver classical 2D drawings and BIM models at LOD 200–400 levels.
