HS2 Works Notification: Notice of demolition of the Heathrow Express Depot

What we are doing

Earlier this year we completed the demolition of the Heathrow Express depot rail-sidings. From 25 October 2021, we will commence the demolition of the Heathrow Express Depot shed. The shed needs to be removed to make way for the construction of the new Great Western Mainline station on the site. These works will be carried out between 8am and 6pm Monday to Friday and 8am to 1pm on Saturdays.

Demolition of the Heathrow Express depot shed
The first stages of demolishing the Heathrow Express depot will be:
1. Removal of cladding panels from the building utilising either an excavator with a grab attachment, or by personnel accessing the panels in a mobile elevated working platform.
2. Demolition of the main steelwork structure utilising excavators with cutting equipment or through use of hot cutting equipment.
Following this, we will commence the removal of the concrete base of the shed.
3. Removal of the foundations utilising excavators
4. Processing of the concrete foundations so that it can be recycled and re-used on site. This will be done by utilising a crusher which will be placed as far East on the site as possible.

Process of demolition
The demolition will be done in stages to minimise the impacts on the community. The map shown on the next page has labelled each elevation as A, B, C and D. Demolition will start with sides, A, B and C leaving elevation D in place to act as a noise barrier. Elevation D will be left in place for as long as possible during the work, including the removal of most of the concrete base. This will help minimise the noise impact for the local community. The final stage of work will involve removing Elevation D and the remaining concrete base.

Managing noise and dust during the works
When the panels are being removed and the steel beams are being cut, there will be additional noise created. There is also expected to be additional noise and dust when the concrete foundations are being broken.
We will continually monitor the dust levels throughout the work. To manage potential dust, we will be damping down (wetting the ground) and using water cannons to mitigate the generation of dust.

Community Engagement
We will be holding a dedicated community meeting to discuss these works in more detail in early November. We will provide further details about this meeting in the next few weeks.
We also hold virtual one-to-one meetings each month. These virtual one-to-ones are an opportunity to find out more about HS2 and what it means for the local area. Please book a slot at www.hs2.org.uk/events

Virtual one-to-one meeting dates:
• 27 October
• 24 November
Time: Between 3pm & 6pm on all dates
Place: Online via MS Teams
