What we are doing
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 Ealing. 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 wrote to you in July about works to install sheet piles at the Mandeville Road Vent Shaft site from 4 August to 5 September 2025. Due to programme changes on site these works will now be carried out from 22 September to 24 October 2025.
These works are to prepare for future works to dig a chamber for a water pump.
These works will include ground excavation and breaking of concrete. The sheet piles will be pushed into the ground.
This works method is quieter than using hammer or vibration methods.
