    Marsh’s Strada and Machina roads insurance: risk and cover notes for UK project teams

    Marsh’s Strada and Machina roads insurance: risk and cover notes for UK project teams

    First reported on The Construction Index

    30 Second Briefing

    Marsh has launched two UK construction insurance facilities: Strada, offering project-specific CAR and TPL cover for road and highway works with exclusive clauses for extensions, open-to-traffic phases and phased completions, and confirmed limits up to £1bn (CAR) and £1m (TPL) plus two months’ free extension cover. Machina provides plant and equipment cover via a single pre-agreed rating matrix for standalone placements or annual programmes, with capacity tailored to project scale. Marsh positions both facilities to address prolonged exposure on road schemes as UK construction is forecast to grow 3.2% annually between 2027 and 2030.

    Technical Brief

    • Strada is underwritten by a panel of global (re)insurers rather than a single carrier.
    • Exclusive Strada clauses target road-specific issues: extensions, open-to-traffic phases, and phased handovers.
    • Marsh notes extension premiums are typically disproportionately high versus original CAR outlay in the wider market.
    • Prolonged exposure arises where carriageways and structures carry traffic before formal completion and handover.
    • Machina is backed by a single “market‑leading” insurer, simplifying counterparty and claims handling.
    • A single pre‑agreed Machina rating matrix is intended to align premium progression with construction programme delivery.
    • Capacity under Machina is flexed per placement, allowing scaling from small plant fleets to major programmes.

    Our Take

    Marsh also appears in our Canada uranium coverage via Marsh Canada’s work around Athabasca Basin assets, signalling that the broker is building sector-specific risk products across both heavy civil infrastructure in the UK and complex mining jurisdictions overseas.

    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.
