Ground movement impact assessment on building foundations using three dimensional finite element analysis. 

Ground movement impact assessment and conceptual design of four structures connecting a new station box with the existing Victoria line platform tunnels.

Design of numerous temporary sprayed concrete lined shaft and tunnel structures, and the waterproofing system for the upgrade of the existing London Underground Tottenham Court Road Station.

Defects surveys of the London Underground existing facilities predicted to settle 1 mm or more due to the planned station upgrade works.

Design of tunnels where they intercept with existing building foundation piles (i.e. at four building locations).

Design of tunnels and shafts (primary lining, waterproofing and secondary lining). Design representation on site during construction.

Assessment of the impact on existing cast-iron and precast concrete tunnel linings (in total approximately 300 assets.) including empirical and finite element calculations.

Tunnel and shaft design, construction support during excavation and primary lining works.

Tunnel design, engineering support, geotechnical engineering and site supervision services were provided.

Design of the primary and secondary sprayed concrete linings, 3D FE modelling of all SCL tunnels including excavation steps and ground movement assessments.
