Notice of borehole works and installation of monitoring equipment, Gloucester Avenue

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 Camden. 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. 

From 8 October to 10 October we will be decommissioning a borehole at 42 Gloucester Avenue, ahead of future tunnelling works in the area.

We will also install monitoring equipment at the back of the building facing the train tracks. The equipment will allow us to monitor any ground movement before, during and after our tunnelling works.

We will put barriers around the borehole, unblock it, if necessary, refill it with grout and then tarmac over it. This will take up to three hours, but the barriers will stay in place until the grout and tarmac are dry. We will set up scaffolding and use handheld drills to install the monitoring equipment. The equipment will remain in place for around two years before being removed.
