Tunnels

BuildConex provides forensic analysis for tunnelling disputes involving geological risk, TBM performance and support-type changes.

Our Approach

Tunnelling disputes are often driven by geological risk and sequential delay. We analyse TBM advance rates, face stability events and support-type changes, then connect them to the contemporaneous programme and cost records to establish causation.

Our Capability

We assess delay in hard-rock and soft-ground conditions, value overbreak and sprayed concrete claims, review geotechnical and support records, and prepare expert reports for dispute resolution.

Key Areas

• TBM delay and advance rate analysis
• Geological face stability and support claims
• Overbreak and sprayed concrete quantum
• Shaft and portal construction disputes

Outcomes

Our analysis provides a credible basis for evaluating geological and support-related claims, helping parties distinguish between foreseeable risk and compensable delay.
