Working on behalf of main contractor BAM Construction, Elland Steel has installed precast staircases, 7,500m² of 200mm-deep precast flooring, structural roof decking and 570t of structural steelwork.
The new school, which will include a sixth form, will provide places for 1,400 pupils.
Architecturally, the school is set over two and three-storeys, with four wings radiating from a central hub.
The project also includes a four-court sports hall, two dining halls, main assembly hall, and a central faith area with an ETFE dome.
An extensive solar array on the roof will allow it to meet the requirements of the London Plan, which is a strategic plan for the capital setting out an integrated economic, environmental, transport and social framework
There will be electric charging points in the car park, and the football field will be used for storm attenuation.
