Forest City 1 Cambridgeshire: metro, SMR and desalination risks for engineers

Forest City 1 Cambridgeshire: metro, SMR and desalination risks for engineers

First reported on New Civil Engineer

30 Second Briefing

Plans for Forest City 1 (FC1), a proposed new urban hub in Cambridgeshire, envisage a dedicated metro system, a small modular reactor (SMR) for local low‑carbon power, and a coastal desalination plant to balance its water demand. The concept implies substantial new linear infrastructure, with metro corridors and power and water transmission routes needing early safeguarding in predominantly rural, low‑lying ground. For engineers, the combination of SMR siting, long water pipelines from the coast, and potential tunnelling for metro alignments will drive geotechnical risk, consents strategy and upfront capital costs.

Technical Brief

  • FC1 backers indicate metro, SMR and desalination are all pre‑requisites, not optional enhancements.
  • Promoter positions FC1 as a single large new settlement, not incremental expansion of existing towns.
  • Cambridgeshire’s flat, low‑lying topography implies long, shallow‑gradient corridors for both rail and pipelines.
  • Agricultural land take and severance along linear corridors will drive early land assembly and compensation strategy.
  • For similar UK new‑town concepts, early safeguarding of multi‑utility corridors is becoming a central planning test.

Our Take

Cambridgeshire rarely features in our 880-item Infrastructure corpus for city-scale greenfield schemes, so Forest City 1 would sit at the more experimental end of UK planning compared with the incremental upgrades that dominate coverage.

New Civil Engineer’s recent webinars on BIM, common data environments and digital handover suggest any FC1 metro and SMR–desalination assets would be under pressure to adopt tightly integrated digital delivery from the outset to avoid lifecycle data gaps.

With 2,358 tag-matched ‘Projects’ and ‘Sustainability’ pieces in our database, FC1’s combination of transport, nuclear-derived power and water infrastructure would place it among a small subset of UK schemes attempting multi-utility decarbonisation in a single masterplan.

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.
