What we are doing
We are building two ventilation (vent) shafts and a headhouse at the Mandeville Road site in Northolt.
This work will require regular concrete pours for works in the satellite shaft and to build the headhouse base slab.
The number of concrete pours each month are as following:
- July – five;
- August – seven.
The concrete pours can take around 16 to 20 hours. We expect all the pours to start at 6am but they will have varied finish times. There will be a delivery of machinery between 4am and 5am in advance of the concrete pour. The machinery will be removed once the concrete pour is complete. We will close Mandeville Road for about 15 minutes to reverse a lorry out of the site to remove the machinery.
While on-site work is not expected to cause additional disruption, there will be periods of noise from the concrete pour and concrete delivery vehicles. Traffic marshals will guide delivery vehicles as usual. Noise and vibration monitoring will also continue.
For details of concrete pour in each month, please follow the links to the notifications below.
