DEMOLITION OF the fi re ravaged Torre Windsor in Madrid was delayed this week by strong winds preventing work at height.
Deconstruction of the 98m tall building was due to start on Saturday but was held up due to the bad weather, which included snow as well as gale force winds.
Details of the demolition plans released this week by the Madrid authorities state that taking down the tower block will cost £12.5M and take up to 11 months.
Contractor Ortiz Construcciones y Proyectos has been employed to dismantle the structure under the supervision of the Madrid Department of Building Control.
A total of four tower cranes will be used to demolish the building. They will start by removing the fire-damaged crane on top of the structure before taking down the mangled steel facade, outer concrete slabs and columns. The concrete core will be tackled last.
A mathematical model is being used to ensure that the deconstruction works do not trigger a structural failure. Stresses across the structure will be analysed as elements are removed.
City offi ials said that radio controlled robots that can operate clamps, cutting discs and shears will be used to cut and remove the mangled steel and concrete, keeping manual intervention to a minimum.
