Context
A major transport-tunnel project in Serbia, requiring an independent technical review of the design approach and a set of recommendations grounded in both geological risk and financial-sustainability exposure.
Scope
Review of the design comments and recommendations on tunnel section geometry, excavation approach, ground-support strategy, and the geological-uncertainty assumptions that drive the project's cost envelope.
Framework
Our team's published research on the financial sustainability of underground projects — in particular the relationship between the quality of preliminary geological investigations and the variance of project outcomes — underpins the review methodology. A benchmark of approximately EUR 35 million per kilometre (±12 million) for comparable projects is referenced from the published work.
What the engagement illustrates
Geotechnical depth is not a side discipline for ISR. It is one of the two capability pillars on which the firm is built. Where a mining project has a significant underground component — or where a client's risk exposure is dominated by subsurface unknowns — the same methodology applies.
Attribution — Drawn from our principals' and network track record. The underlying research on geological uncertainty and underground-project financial sustainability has been peer-reviewed and published.
