HS2 Curzon Street piling completion: programme and foundation notes for engineers

30 Second Briefing
Completion of more than 2,000 concrete piles for HS2’s Curzon Street station in Birmingham marks the end of the main deep-foundation phase for the city-centre terminus. The piled foundations will carry the station’s multi-platform superstructure and associated over-track development, designed to accommodate high-speed rail loads and complex urban constraints. With piling finished, contractors can shift resources to pile caps, ground beams and station box works, compressing the programme’s critical path for structural and rail systems installation.
Technical Brief
- Piling completion allows transfer of heavy plant and labour to superstructure and station box works.
- Urban setting likely demanded strict vibration, noise and working-hour controls during piling operations.
- Completion of deep foundations reduces geotechnical risk on the programme’s critical path.
Our Take
Curzon Street piling completion in Birmingham sits alongside HS2’s planned 18‑month Saltley Viaduct replacement on the A47, signalling that disruptive heavy civil works around the city’s rail approaches will overlap and need tight traffic and stakeholder management.
With Keltbray delivering 2,011 CFA piles for Curzon Street under the Mace Dragados JV and Ferrovial Bam and Ayesa/Egis engaged on HS2 track systems, our coverage shows HS2 increasingly segmented into specialist packages, which can complicate interface risk at key nodes like Birmingham.
Among the 728 Infrastructure stories in our database, HS2 appears frequently as a multi-node programme (Curzon Street, Euston PPP, Saltley Viaduct), so contractors working in Birmingham should expect sustained procurement and coordination activity rather than a single peak of construction demand.
