The Project:

The proposal is to construct new platform canopies to the Country End of platforms 2, 3 and 4 of Ealing Broadway Station. The canopy to platform 2/3 is approximately 45m long and 8.25m wide, platform 4 canopy is approximately 8m long by 8m wide. The proposed canopy’s interface with existing platform structures such as the existing canopy of platform 4 and the waiting room and AFA stairs on platform 2/3 but are structurally independent.

Both canopies can easily be extended in bays if required in the future.

The design intent is to have modern structures that align with the modern AFA overbridge

Blast analysis – the station had recently be recategorised as a CAT A station meaning the canopies had to be designed and fabricated in such a way that they could withstand a blast from any suspected packages placed at the bases of the columns and not collapse but dissipate the anticipated blast.
