    Trenchless microtunnelling in Italy and Germany: design lessons for urban engineers

    Trenchless microtunnelling in Italy and Germany: design lessons for urban engineers

    First reported on New Civil Engineer

    30 Second Briefing

    Trenchless tunnelling schemes in Germany and Italy are using microtunnelling to install new utility and wastewater pipelines under urban areas while avoiding open-cut excavation and major traffic disruption. The projects deploy remotely steered, pipe-jacked microtunnel boring machines launched from small shafts to thread beneath existing roads and buried services, maintaining cover and line within tight tolerances. For geotechnical and civil teams, the work reinforces microtunnelling as a practical option where shallow cover, dense service corridors and strict surface access constraints rule out conventional trenching.

    Technical Brief

    • Similar microtunnelling arrangements are increasingly being adopted on constrained European wastewater renewal schemes.

    Our Take

    New Civil Engineer appears in several of our recent Infrastructure pieces as a convenor of technical debates (BIM data handover, bridge retrofit, airport innovation), so its coverage of microtunnelling in Germany and Italy is likely to feed into UK-focused best-practice discussions rather than just report continental case studies.

    Germany and Italy feature less frequently than the UK in our Projects-tagged infrastructure items, which suggests these microtunnelling examples may be used as reference cases for clients and designers working under different regulatory and urban constraints than those typically discussed in British schemes.

    Strabag’s Pfaffensteig Tunnel contract: design and delivery notes for rail engineers

    Strabag and Group company Züblin have secured the design-and-build structural works for the ABS Gäubahn Nord/Pfaffensteig Tunnel in south-west Germany, centred on an 11km twin-bore rail tunnel linking Stuttgart Airport station directly to the Gäubahn line towards Switzerland. About 9.8km will be driven by two TBMs, with conventional tunnelling for the A8 motorway undercrossing and airport connection, plus a 240m cut-and-cover section, retaining structures, railway underpasses and a grade-separated crossing. A 3km surface section will be upgraded and partially realigned for 200km/h operation, delivered under an integrated project delivery model with Ed. Züblin, Wayss & Freytag and Strabag AG sharing tunnelling, structural and earthworks packages.

    National Grid TBM under the Thames: tunnelling design and risk notes for engineers

    A 271.5‑tonne Herrenknecht Mixshield TBM, Caroline, has started driving a 2.2km electricity cable tunnel with a 4m internal diameter beneath the River Thames in Essex for National Grid’s Grain to Tilbury project, delivered by the Ferrovial BEMO joint venture. The drive will pass through variable Thames estuary ground conditions between 35m‑deep launch and reception shafts of 15m and 12m diameter, with tunnelling continuing into 2026 and overall scheme completion targeted for 2029. The new tunnel will replace the 1969 Thames Cable Tunnel and carry new high‑voltage circuits between Grain and Tilbury substations.

    Panama Canal Mixshield undercrossing: design and tunnelling lessons for engineers

    A 13.46m diameter Herrenknecht Mixshield TBM has broken through into the future Balboa station on Panama Metro Line 3 after completing the first-ever TBM undercrossing of the Panama Canal at depths exceeding 60m below sea level. The 5,600kW, 26,616kNm machine, fitted with an accessible cutterhead and more than 4,500 sensors linked via the Herrenknecht.Connected platform, has achieved peak advance of 150 segment rings (about 300m) per month through mixed sandstone, tuff, breccias and basalt. Around 1.5km of the 4.5km twin-track tunnel remains to final breakthrough.
