Two tower cranes have been in place to lift panels from the building, one strip at a time, before the new glazing and curtain walling were installed using mast climbers. This method has allowed the building to remain substantially watertight, as well as keeping everyone safe on the ground within the city-centre site.
The concrete panels have been taken away to a quarry in Bramhope, Leeds, where they have had the steel reinforcement extracted and recycled before the remaining concrete is crushed and certified for reuse for other construction projects.
