What we are doing
Excavation of HS2 station box is ongoing
The new state of the art HS2 station building and platforms, will be made of reinforced concrete, both on the surface and underground. To construct the HS2 station (site location shown on page 2), we will excavate down within the boundaries of an area called a ‘box’ and pour concrete to form the outline of the structure.
Before excavation begins in each section of works, we will break down the top of the existing concrete diaphragm wall (D-wall). The D-wall runs underground along the outside of the station box, to help support the area whilst excavation takes place. After removing the top of the D-Wall, a concrete ‘capping beam’ is placed on top to stiffen the perimeter ahead of the excavation phase. We are in the process of pouring concrete for the capping beam around the outline of the station box.
Excavation is ongoing in the western end of the site and from September 2022, the excavated material will be removed by the conveyor system that takes materials to the Willesden European Terminal (WET) for onward use.
Extended working hours for concrete pours
From 19 September until April 2026, we will start pouring concrete to construct the underground floors of the HS2 station box. This will initially take place in the west side of the Old Oak Common site, as shown in the map on Page 2.
For safety reasons a concrete pour must be completed in one session, otherwise the concrete can be weakened. For larger concrete pours, this is not always achievable within the current working hours and therefore requires longer working hours to complete the pour successfully. On the day of these concrete pours, we will work for extended working hours from 8am until 9pm on weekdays and 8am until 5pm on Saturdays.
