    Strabag acquires GTDS: implications for HV transmission project teams

    Strabag acquires GTDS: implications for HV transmission project teams

    First reported on The Construction Index

    30 Second Briefing

    Strabag UK has acquired the assets of Gunning Transmission & Distribution Services (GTDS) from Ethical Power Group to accelerate its move into regulated high-voltage transmission and commissioning work in the UK and Ireland. GTDS, which will continue operating from its Stafford offices, has grown turnover from £16m in 2022 to £96m in the year to August 2024, bringing an established client base and specialist HV installation capability. The deal gives Strabag in-house expertise for power infrastructure programmes linked to upgrading and modernising the UK electricity network.

    Technical Brief

    • Acquisition covers “various assets” of Gunning Transmission & Distribution Services rather than a full share purchase.
    • GTDS revenue has increased six-fold in two years, from £16m (2022) to £96m (2024).
    • Turnover more than doubled between 2023 and 2024 alone, rising from £44m to £96m.
    • This new area of the business will continue to operate from GTDS offices in Stafford, maintaining continuity for both clients and employees.

    Our Take

    Strabag already features in our UK infrastructure coverage through the Skanska Costain Strabag Joint Venture on HS2, so acquiring Stafford-based GTDS deepens its local delivery base in a market where it is already a tier‑one player on mega-projects.

    GTDS’s rapid revenue growth from £16m in 2022 to £96m in the year to August 2024 signals strong demand in UK transmission and distribution work, which should give Strabag UK immediate scale in grid‑connection packages for renewables and data‑centre projects.

    Alongside Strabag’s recent wins on complex assets such as the Fehmarn Sound immersed tunnel, adding a specialist like Gunning Transmission & Distribution Services suggests a strategy of pairing large civil packages with in‑house power and grid capability for integrated bids.

    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.
