Update: Piling and drainage installation works for noise barrier sites

Safe stop down to SCS works from 10 October 

Safety is our number one priority at HS2. Following an incident that occurred at the Green Park Way site in Ealing, works are being safely halted across the London Tunnels section of the route, including sites in Hillingdon. While no workers were physically harmed, our contractor, Skanska Costain STRABAG joint venture, is undertaking a comprehensive review of safety procedures and leadership on their sites before a safe restart can take place. 

Works will be brought to a safe stop and will remain on hold until we’re satisfied that all appropriate measures are in place to protect the workforce. We anticipate the review may take a number of weeks depending on the area and the type of work involved. 

We will provide details on when the safe stop will be in place over the course of the next week. 

We planned to carry out the installation of noise barriers and drainage systems along the HS2 route from Copthall Tunnel to West Ruislip Portal sites, from 30 June 2025 to 27 March 2026.

However, these works have been rescheduled, and we will now be starting from 28 July 2025.

We will start by installing concrete piles to stabilise the ground, followed by the installation of drainage systems. Our working hours will be Monday to Friday 8am to 6pm and Saturday 8am to 1pm.

You may notice periods of increased noise during these works. However, noise monitoring will take place throughout the works.
