Ground Conditions Change. Your Data Doesn't.
Packer test results. Grout mix designs. Geotechnical logs from probe drilling. When the TBM hits something unexpected, you need history—not a folder full of CSVs.
The Ground Surprise Problem
The TBM hit water at chainage 847. The probe drilling said it would be dry. Now you need every packer test from the SI phase, the grout injection records from the last wet zone, and the decision trail that led here.
The SI contractor finished 18 months ago.
When hydrogeological data lives in a purpose-built database, retrieving 18-month-old SI data takes seconds with the right filters.
Two Tools for Tunnelling Workflows
Water management and material quality—the two places where tunnelling projects live or die.
Hydrogeological Testing
When the grouting contractor asks "what was the K value at chainage 820?" you have an answer—and the full audit trail to back it up.
- —Two Lugeon formulas on every packer test
- —Permeability zonation across the alignment
- —Water ingress prediction data
- —Grouting design support
Quality Control Database
Two-component grout tracking from batch plant to segment. Component A/B ratios, cure times, strength development—everything linked to ring number.
- —Grout mix design management
- —UCS testing with cure time tracking
- —Segment-to-batch traceability
- —Multi-laboratory comparison
What Changes When Your Data Survives the SI Phase
Ground surprises become data lookups.
When the TBM encounters unexpected conditions, the SI data from that zone is one search away. No handover gaps.
Grout injection history stays with the ring.
Ring 147 leaked? You'll know the mix design, the component ratios, the cure time, and the QC results for that exact injection.
Contractor handovers don't break continuity.
When the SI contractor demobilises and the construction JV takes over, the data stays in the same place it always was.
When the TBM Hits Something Unexpected
You'll have the packer test history. The grout mix records. The decisions that got you here. 14-day trial, full access.
