    Morgan Sindall’s Sellafield SRP milestone: design and risk notes for engineers

    First reported on New Civil Engineer

    30 Second Briefing

    Progress on Morgan Sindall’s Sellafield Product and Residue Store Retreatment Plant (SRP) has reached an “important milestone” within the Programme and Project Partners (PPP) framework, advancing a key facility for long-term management of high-hazard nuclear residues. The SRP will retreat and condition legacy product and residue wastes from existing stores on the Sellafield site, preparing them for safe encapsulation and future geological disposal. For civil and nuclear engineers, the project is a major reference for complex reinforced concrete, containment and remote-handling infrastructure in a highly regulated brownfield environment.

    Technical Brief

    • SRP delivery sits within Sellafield’s long-term Programme and Project Partners (PPP) alliancing framework with Morgan Sindall.

    Our Take

    Morgan Sindall appears repeatedly in our recent UK Infrastructure coverage, from Network Rail’s Portishead line reinstatement to leisure and education builds, signalling that its Sellafield Product and Residue Store Retreatment Plant role sits within a broader push into technically demanding public-sector frameworks.

    Morgan Sindall’s participation in RICS’s CLEAR life‑cycle emissions initiative suggests that sustainability methods piloted on more conventional schemes (schools, leisure centres, housing) are likely to inform how whole‑life carbon and materials tracking are handled on complex nuclear decommissioning projects like SRP.

    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.
