    Rhosafan’s new school: net‑zero design and materials insights for engineers

    First reported on The Construction Index

    30 Second Briefing

    Construction has started on Neath Port Talbot Council’s £29m Rhosafan Welsh Medium Primary School, a 420-place, net-zero-in-operation facility with 90 nursery places, 12 ALN places and a 16-place Welsh Immersion Unit, delivered by Morgan Sindall through the South West Wales Regional Contractors Framework. The scheme uses a hybrid timber and steel frame, roof-mounted photovoltaic panels, a centralised air source heat pump plant, underfloor heating and BMS-controlled night purge ventilation, targeting BREEAM Outstanding, Secure by Design and Carbon Net Zero standards. External works include three MUGA pitches, a 110-space permeable car park with bio-retention rain gardens, and an 810 sqm steel-frame plus single-storey timber-frame “winter garden” structure to support outdoor learning.

    Technical Brief

    • £29m scheme is being delivered in two construction phases, with final completion targeted for 2028.
    • Accommodation schedule includes 16 classrooms, five meeting rooms, a staff room and a dance studio.
    • Car park design provides 110 spaces using permeable surfacing over bio-retention rain gardens for on-plot attenuation.
    • Winter garden comprises a two-storey, 810 m² steel-frame block plus a single-storey timber-frame element.
    • Project team includes Arcadia Architects, Stantec (consulting engineer), Fenton Reece (landscape) and specialist fire/acoustic consultants.

    Our Take

    Rhosafan Welsh Medium Primary School continues a clear pipeline of education work for Morgan Sindall Construction in the UK, following recent school projects at Kingsbrook in Aylesbury and Broadford Primary on Skye, which suggests the contractor is consolidating a strong position in local-authority-funded education frameworks.

    With 420 primary places plus dedicated ALN and Welsh immersion capacity, this Rhosafan project signals how Welsh government-backed education builds are now routinely embedding specialist provision into base designs, which can have implications for future space planning standards across other councils in South West Wales.

    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.
