    Jacobs, GHD and WSP Sydney Metro West stations: design and risk lens for engineers

    Jacobs, GHD and WSP Sydney Metro West stations: design and risk lens for engineers

    First reported on New Civil Engineer

    30 Second Briefing

    Jacobs, GHD and WSP have been appointed in a joint venture by lead contractor Gamuda to design five underground stations for the Sydney Metro West project. The commission covers full multidisciplinary design for deep excavations, underground caverns and associated tunnel interfaces on one of Australia’s largest urban rail schemes. The work will demand complex geotechnical modelling, groundwater control and temporary works design to manage settlement risks to adjacent buildings and existing utilities in dense inner-city conditions.

    Technical Brief

    • Multidisciplinary remit includes structural, geotechnical, building services, fire/life safety and rail systems integration.
    • JV will be responsible for constructability input, staging of excavation and station box construction methodologies.
    • Integration of permanent works design with temporary support and propping schemes will be a single coordinated package.
    • Close collaboration is required with utility owners to protect and, where necessary, divert buried services around station boxes.

    Our Take

    Jacobs’ role on Sydney Metro West comes soon after it moved to full ownership of PA Consulting in the UK, signalling a push to combine in-house advisory and systems expertise with major design delivery on complex rail schemes.

    In our infrastructure coverage, Sydney appears frequently alongside Melbourne as a focal point for Australian urban rail expansion, so this JV work with Gamuda positions Jacobs, GHD and WSP well for follow-on station and precinct packages as the programme phases progress.

    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.
