Grade II* listed façade
Protecting heritage with advanced analysis
Excavating a deep basement to maximise development space would have caused local ground movements and devastating damage to the Grade II* listed façade to the Old War Office building in Whitehall, London.
Detailed 3D finite element analysis (FEA) of the complex, phased basement construction sequence using advanced non-linear soil models allowed the construction sequence to be adapted to ensure the priceless facade suffered no damage.
