    Regenerating Stevenage: phasing and retrofit lessons for new town project teams

    Regenerating Stevenage: phasing and retrofit lessons for new town project teams

    First reported on New Civil Engineer

    30 Second Briefing

    Stevenage Borough Council is partnering with Mace and other developers on a comprehensive town centre regeneration that reconfigures the original post‑war new town layout for higher‑density mixed use, active travel and modern utilities. The programme focuses on retrofitting 1950s concrete structures, rationalising multi‑storey car parks into development plots, and upgrading public realm and transport interchanges to handle contemporary pedestrian and bus flows. Lessons on phasing works around ageing services, constrained town‑centre highways and existing retail cores are being treated as a template for the UK Government’s proposed new wave of new towns.

    Technical Brief

    • Lessons on working within fully occupied town centres are being positioned as a reference for future new towns.

    Our Take

    Mace’s role in Stevenage regeneration sits alongside its work on complex UK schemes like HS2 Curzon Street station piling and the Paddington over-station development, signalling that Stevenage Borough Council is tapping a contractor with current experience in dense, transport-integrated urban sites.

    With Mace Group having recently demerged and sold a majority stake in Mace Consult to Goldman Sachs Alternatives, governance and risk appetite on long-horizon town-centre regeneration in the United Kingdom may be influenced by a clearer separation between its construction and consultancy balance sheets.

    Among the 731 Infrastructure stories in our database, relatively few UK local-authority-led pieces feature the same repeat contractor presence as Mace, suggesting Stevenage Borough Council is likely to benefit from cross-project learning that Mace has accumulated on sustainability-focused refurbishments such as the St Magnus House façade replacement.

    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.

    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.
