Tunnel Works
Tunnel Works
Underground delivery supported by TBM, pipe-jacking and specialist tunnel construction methods.

Tunnel and underground works require stronger control over ground conditions, settlement, alignment precision and construction safety than many conventional civil packages.
Allied Way can combine TBM, pipe-jacking and other underground methods where appropriate to improve execution stability and reduce disruption to surrounding assets and environments.
These capabilities are particularly relevant for constrained sites, long underground alignments and projects with demanding steering requirements.
Key Focus
- • TBM and pipe-jacking methods
- • Underground risk and settlement control
- • Precision steering in constrained sites
