Renewal & Rehabilitation
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
