Peace of mind for Battersea Dogs and Cats Home

The new Veterinary Hospital and Centre of Excellence (VHCE) was constructed about a year before the Northern Line Extension (NLE) tunnels were excavated nearby. Designers needed to ensure that this brand new building would not be damaged by ground movements induced by the forthcoming overrun tunnels.

Advanced geotechnical FEA of the new building's construction and subsequent adjacent tunnellling showed that the building (as well as the cats and dogs!) were safe.

Highlights

• Geotechnical FEA model of proposed basement construction, loading and subsequent tunnelling.

• Tunnelling-induced ground movements and building damage category found to be acceptable.

• Category 3 check of piled foundation and basement wall design for Network Rail.

• 3-year post-construction and tunnelling settlements measured by DInSAR to be only about 5mm.
