Skanska, as part of the Skanska Costain STRABAG joint venture is delivering full detailed design and construction of Phase One of the UK's new high-speed railway in the southern section of the overall High Speed Two (HS2) project.
The contract involves the construction of major tunnels in the approach to the London terminus at Euston station of the Phase One route. The route length being delivered by the joint venture covers just over 26km, with two 21km long and up to 50m deep tunnels running from the London terminus at Euston station to West Ruislip.
Six giant tunnel boring machines (TBMs) will be used to excavate the 21km route, while a seventh TBM will excavate a logistics tunnel, to be used to bring construction materials into the tunnels and remove muck. The first two TBMs will go nonstop for 22 months while the whole tunnelling programme is expected to take three years from the start of the first TBM drive to final breakthrough.
Delivering complex high speed rail infrastructure
Working on the biggest infrastructure project in Europe, we have the opportunity to develop and implement new construction techniques that deliver a step-change and long-lasting benefits for our industry. This includes our approach to driving down carbon that supports government targets and our own ambition to be net-zero carbon by 2045.
Through our work on the London tunnels as part of the Skanska Costain STRABAG JV, we are developing and implementing solutions that cut carbon and deliver wider societal benefits – including cost reduction, improved safety and quicker delivery.
Leaving a lasting legacy
Creating a lasting legacy in the areas where we operate is a priority for our project team. Our expert JV teams employ around 4,800 people, including supply chain. This includes over 300 people from local communities brought in through a range of training and employment schemes to help those previously homeless, long-term unemployed or vulnerable for other reasons.
Working with seven separate London boroughs across the HS2 route into London, we’re supporting a range of initiatives to boost local economic growth, job opportunities, and community cohesion, in addition to promoting work experience and curriculum focused activities in schools.
This helps to ensure that local communities are well placed to benefit from opportunities the project will create over the next two decades, while supporting HS2 in building the skills base needed to deliver Britain’s future infrastructure ambitions.
