    Dublin MetroLink procurement: lifecycle and O&M implications for project teams

    Dublin MetroLink procurement: lifecycle and O&M implications for project teams

    First reported on New Civil Engineer

    30 Second Briefing

    Transport Infrastructure Ireland has launched procurement for the largest contract on Dublin’s £8.4bn (€9.5bn) MetroLink, covering rolling stock supply, core railway systems and full station fit-out. The package also includes a 25‑year operations and maintenance concession for the driverless metro service, bundling lifecycle responsibility for trains, signalling, power and platform systems. The scale and duration of the contract point to long-term performance-based requirements on systems integration, reliability and maintainability for contractors and their supply chains.

    Technical Brief

    • Procurement is being run directly by Transport Infrastructure Ireland as the contracting authority for the metro.
    • Lifecycle responsibility for trains and core systems will drive whole‑life cost, RAMS and maintainability requirements.
    • Integration of station fit‑out with systems supply should reduce interface risk between civils, M&E and signalling contractors.
    • Long concession term implies performance‑based payment mechanisms tied to availability, headways and safety performance.
    • Single-supplier model will require robust technical standards alignment across rolling stock, signalling, power and platform systems.

    Our Take

    The related tender for a Programme Delivery Partner on MetroLink (flagged in our 2025-12 coverage) signals that TII is formalising a long-term alliancing-style governance model, which contractors will need to factor into bid team composition and dispute-resolution strategies.

    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.
