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.


  • Ground movement analysis for top-down and bottom-up construction options.

  • Tensile force prediction in basement piles due to heave and groundwater pressures. 

  • Heave pressure prediction for basement floor design.

  • Development space on this prime site was maximised.

  • Permanent basement dewatering measures investigated.
