HS2 Phase 1 is the most ambitious rail infrastructure project in the UK in over a century, creating a high-speed link between London and Birmingham. The route includes redeveloped and new stations, extensive tunnelling, cuttings, and deep shaft structures. To support this construction, WJ has been engaged to deliver detailed groundwater control designs that are vital for the successful execution of below-ground works.
WJ’s role spans the full route of Phase 1, providing design expertise for groundwater control measures needed to support excavation and construction activities across a wide variety of geologies and structural configurations.
WJ’s work involves delivering custom groundwater control designs to support:
Key challenges included:
What sets WJ apart is our highly experienced in-house design team, which brings over 130 years of combined expertise to the project. Our capabilities include:
WJ’s involvement has led to the successful completion of 42 groundwater control design packages to date, incorporating data from 28 pumping tests and 17 instrumentation and monitoring systems installed by WJ. These designs have ensured safe excavation conditions, minimized risk, and supported timely construction progress.
At WJ, our design capability is as strong as our field execution. The HS2 design programme showcases our unique ability to deliver engineering-led groundwater control solutions that integrate seamlessly into some of the UK’s most complex construction environments.
