Underground and tunnel engineering
Precision in the most demanding conditions. Surveying services for tunnels, underground passages, and underground infrastructure.
Surveying in underground environments
GEOPRZEM provides comprehensive surveying support for tunnel and underground investments — from preparation, through execution, to monitoring and as-built documentation.
Work in underground environments requires the highest accuracy, continuous control and integration of measurement data into the construction process. We deliver each project individually, adapting technologies and measurement methods to the geological conditions and construction technology.
We support the delivery of
- railway and road tunnels
- underground passages
- underground infrastructure facilities
- linear installations and utility networks
Comprehensive support for underground investments
Full support across every stage of execution — from establishing survey networks to as-built documentation.
Tunnel construction support
- TBM machine support
- excavation geometry control
- precise tunnel control networks
- design-compliance control
Measurements during execution
- structural displacement measurements
- tunnel lining deformation control
- underground structure geometry control
- monitoring of excavation impact on existing structures
As-built documentation
- as-built surveys
- 3D models of tunnels and structures
- documentation for project hand-over
Safety of structures and surroundings
We deliver advanced monitoring during construction and operation of underground facilities.
Monitoring scope
Monitoring of tunnel structural deformations, ground displacements, impact of works on existing infrastructure and ground settlements.
Sensitive surroundings
We pay particular attention to investments carried out beneath road infrastructure, railway lines and urban development.
Work in a high-risk environment
Underground engineering is one of the most demanding areas of construction.
Challenges
- limited space accessibility
- variable geological conditions
- high accuracy requirements
- need for continuous monitoring
Our approach
- precise measurement planning
- integration of data with the construction process
- ongoing analysis of results
- rapid response to changes
