Infrastructure Management
The structural safety and serviceability of underground infrastructure must be ensured throughout its life cycle. Minimal shutdown times, optimal usage of available finances and a long-term plan for measures and investments are at the top of most operators’ wish lists.
As part of the condition assessments, we accompany the value conservation of underground infrastructures, starting with the data acquisition, followed by analysing the data and concluding with designing of any remedial measures. This allows for detailed budget planning and foresighted prioritization of the measures for ensuring operational safety.
Services
We place great emphasis on methodical, structured and seamless recording of the structural condition to enable long-term reliability in planning for you. Costs are provided realistically and transparently, thereby providing a high degree of budget reliability.
PHASE 1 - Preparation
- Acquisition of the owner’s data of the structure, such as:
- Layout drawings
- Detailed drawings
- Construction documentation
- Engineering documents
- Organization & coordination of Phase 2
PHASE 2 – Data acquisition
- Laser scanning
- Visual inspection using high-resolution grey-scale images
- Recording of defects on site using TunnelMap recording software on a tablet
- Material samples and tests
PHASE 3 – Assessment / Analysis
- Direct export of the recorded data to a database
- Full-coverage surface and clearance envelope analysis
- Customizable evaluations and statistical analysis
- Inspections of the structure (material tests, detailed structural safety analysis, etc.)
PHASE 4 – Recommendation of measures
- Determination of the structural condition
- Classification of the tunnel condition
- Suggestions for structural measures
- Presentation of solution options
- Time schedule and cost estimation
- Documentation by means of digital inspection data, CAD drawings and documents
- Recommendations for further investigation and monitoring
- Design and Planning for value conservation and remedial measures
- Comprehensive reporting

Frequently Asked Questions
We deliver integrated asset management and digital solutions that transform infrastructure data into actionable insights. This includes asset management strategies and systems; infrastructure condition assessment and monitoring; lifecycle performance and deterioration modelling; digital twins and asset information models; BIM, GIS, and enterprise system integration; data platforms; analytics and visualisation; and decision-support tools, automation, and AI-enabled workflows.
This service turns data generated across design, construction, and operations into actionable insights for infrastructure owners throughout the whole life of an asset.
Yes. We provide integrated instrumentation & monitoring (I&M) solutions: monitoring scheme design, data acquisition and management, real-time monitoring platforms, predictive analytics and reporting and interpretation. We design monitoring schemes for tunnels, shafts, and surrounding structures and interpret the data to confirm that the ground and structures behave as predicted — and to trigger corrective action where needed.
Much of the world's tunnel and infrastructure stock is ageing, and renewal is a major focus. We assess the condition of existing structures (laser scanning, high-resolution visual inspection, material testing, TunnelMap recording), analyse the data, classify the condition, and recommend remedial measures — with realistic, transparent cost estimates to support reliable budget planning.
Based on the assessment, we develop maintenance plans and refurbishment concepts and recommend future-proofing strategies that balance cost, availability and long-term performance — minimising shutdown times.
We provide lifecycle-oriented solutions for long-term operational performance: condition assessment, maintenance strategies, digital inventories and digital twins, asset management systems and decision-support tools. We help owners manage their infrastructure strategically throughout its entire lifecycle, supported by monitoring, data, and analytics.
