Crayford

Start of works at Crayford site

Since March 2022, the project team started working an 8 am – 6 pm shift pattern at the Crayford site.

The team is currently setting up the site, using private land access to minimise disruption and accessing the site via the Ladbrokes dog track.

We will build a deep tunnel shaft at our Crayford site to receive the tunnel boring machine from our Hurst substation site. The machine will be removed and dismantled at this location and a headhouse building will be constructed to cover the shaft and provide ventilation and access to the tunnel once it has been built.

The new tunnel will connect our substation at Hurst to the terminal tower at Crayford.

The Crayford site is located on Crayford Rough in the London Borough of Bexley, to the south of the Crayford Greyhound Track and next to the Crayford terminal tower.

Planning approval from the London Borough of Bexley for the headhouse and temporary access road through Stadium Way, past the Greyhound Stadium, was received in December 2019. We have also received permission for permanent flood compensation storage areas in Crayford Rough as the site is within a flood zone.

Site specific FAQs

Access

We are currently accessing the site via Stadium Way and through Ladbrokes dog track to minimise impact to the public using the footpath next to the site.

Traffic

We anticipate that there will be a low volume of HGV movements – approximately 6 HGV movements per day during shaft construction, and 4 per week during headhouse construction.

Working hours

Site working hours will be 8am to 6pm Monday to Friday, and 8am to 1pm on Saturdays. No work on Sundays or Bank Holidays is expected.

Dimensions

The shaft will be approximately 12.5m in diameter and 16m deep.  The headhouse will reach a maximum height of 10m.
