    RADIX OneFit modular screw pile system: design and constructability notes for engineers

    RADIX OneFit modular screw pile system: design and constructability notes for engineers

    First reported on The Construction Index

    30 Second Briefing

    RADIX has launched OneFit, a modular screw pile and helical pile foundation system built around a single connection standard so pile leads, helices, extensions and terminations can be mixed and matched on site. Crews can switch between helical pile configurations and complete screw piles using the same rig and stock components, allowing rapid reconfiguration for variable ground conditions without bespoke fabrication or programme delays. Targeted at BESS pads, bridge foundations and modular construction, the system aims to minimise excavation and spoil while giving RADIX a platform to expand into full engineered foundation systems.

    Technical Brief

    • OneFit’s single mechanical connection detail allows pile leads, helices, extensions and terminations to be interchanged on site.
    • RADIX engineers have designed the components to function as one engineered system rather than standalone items.
    • Stocked components are intended to remove lead times for bespoke fabrication when ground conditions deviate from investigation data.
    • A common connection lets crews swap between helical-only and full screw pile assemblies without changing rigs or tooling.
    • RADIX positions OneFit for modular construction, where variable bearing strata and tight programmes limit conventional cast-in-place options.
    • The system is conceived as extensible, with future additional component types and variations planned within the same interface standard.

    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.
