    Hamer to replace Sheffield on Royal Bam board: delivery and risk takeaways for project teams

    Hamer to replace Sheffield on Royal Bam board: delivery and risk takeaways for project teams

    First reported on The Construction Index

    30 Second Briefing

    Former Sir Robert McAlpine chief executive Paul Hamer will be nominated to join Royal Bam Group’s supervisory board at the Dutch contractor’s AGM in May 2025, replacing outgoing British board member Paul Sheffield. Sheffield, ex-chief executive of Kier and former Laing O’Rourke director, steps down after roughly nine years on Bam’s supervisory board, having first joined in 2017 and secured multiple reappointments. Hamer previously led WYG for nine years before his 2017–2024 tenure at Sir Robert McAlpine, giving Bam a board member with both consulting and major contracting experience.

    Technical Brief

    • Sheffield’s supervisory board tenure runs to the end of a one-year reappointment granted for 2025.
    • His original appointment dates from 2017, with a further full reappointment cycle in 2021.
    • Sheffield’s prior executive career includes nearly 30 years at Kier, last three as chief executive.
    • He also spent three years at Laing O’Rourke from 2014, covering major UK infrastructure delivery.
    • Hamer’s leadership background spans consulting engineering (WYG) and Tier 1 contracting (Sir Robert McAlpine).
    • Bam’s central works council has formally supported Hamer’s nomination, indicating internal stakeholder alignment.

    Our Take

    Royal Bam Group appears frequently in our infrastructure coverage through Bam and Bam Nuttall project work, including the Cardiff Central station upgrade and the south Dublin link road, so board-level changes will likely influence UK and Ireland transport bids and risk appetite rather than being purely Dutch‑focused governance moves.

    Given Paul Hamer’s background with Kier, Sir Robert McAlpine and Laing O’Rourke, his appointment brings a network drawn from most of the major UK Tier 1 contractors, which can be strategically useful as Bam competes for complex public‑sector frameworks in the United Kingdom.

    Our database shows Bam’s recent UK and Irish work is heavily weighted towards transport and urban infrastructure, so supervisory board experience in managing long-duration, politically exposed projects will be directly relevant to delivery risk on schemes like Cardiff Central and the Dublin link road.

    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.

    Hudson Tunnel funding deadline: schedule and risk takeaways for project teams

    Federal funding for New York’s US$16bn Hudson Tunnel Project has been frozen, forcing the Gateway Development Commission to suspend works from 6 February after spending over US$1bn and employing about 1,000 site workers. A Manhattan federal judge has issued a temporary restraining order, giving the administration until 5 p.m. on 12 February to restore reimbursements or appeal, while contractors warn that demobilisation, resequencing and remobilisation will add cost and delay. Sites are now in “safe-pause” mode, with dewatering, ground support and environmental monitoring maintained, and assembly of two Herrenknecht TBMs in New Jersey likely to slip beyond the planned spring 2026 launch without funding certainty.

    Implenia/Marti JV MehrSpur Zurich–Winterthur: design and risk notes for engineers

    Swiss Federal Railways has awarded an Implenia/Marti 50:50 joint venture five of six MehrSpur Zurich–Winterthur lots worth just under CHF 1.7 billion, including the 8.3 km Brüttener tunnel (Lot 240) with twin 10 m diameter single-track tubes and a 1 km spur to Zurich Airport. TBM excavation will start in August 2029, with a roughly ten-year construction phase using BIM for planning and execution and extensive special foundations, earthworks and embankments. Additional works cover full redevelopment of Dietlikon station, about 6 km of new track across Dietlikon and Wallisellen sections, multiple underpasses, bridges and the Neumühle railway bridge and Storchen underpass near Winterthur.
