This time lapse video shows the construction of a new protection deck over the London Overground station platforms at Whitechapel.
The protection deck frame is divided into two sections classified by the weight that the deck can support. The construction of the heavy deck (capable of supporting heavy loads like construction machinery) is shown in this video, construction of the light deck with commence soon.
Nine pairs of 13.5 m long rafter beams were used to create the heavy deck. The beams have a special coating to make them fire resistant and each pair has a combined weight of approximately ten tonnes. Two 130 tonne crawler cranes were used to lift the beams into position.
For the safety of our workers, and to minimise the disruption to rail passenger and Swanlea school, the majority of work for the deck is being carried out at night when the railway is closed.
When completed, the deck will allow Crossrail’s Durward Street shaft to be constructed whilst maintaining rail services.
