Update: 24-hour work on Mondays to Fridays and extended working hours on Saturday at Mandeville Road site

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. 

24-hour work on Mondays to Fridays at Mandeville Road site extended until 13 October 2025

We wrote to you earlier this month about our works below ground to connect the main shaft to the tunnel, 24 hours a day, Monday to Friday, until 3 October 2025. These works have taken longer than expected and are now due to finish on 13 October 2025.

The works include digging into concrete, wire cutting below ground and removing the concrete blocks from the shaft using a crane.

Extended working hours on Saturdays

We normally work above ground on site from 8am to 1pm on Saturdays. As part of our works to build the headhouse we may need to work until 6pm on some Saturdays until 31 October 2025. We will only work these extended hours when required, not every Saturday.

During the extended hours, we will continue to build the headhouse base slab by the main shaft. A crane will be in use during this works.
