The project relates to various improvements at Euston Station including the provision of new lifts from within the Station Concourse down to London Underground Ticket Hall level with an intermediate stop at Taxi Drop-Off level.

Due to proximity of the Northern line running tunnel it has been necessary to work with London Underground to establish the precise 3D positioning of the tunnel and prepare calculations assessing the potential impact of the enabling and permanent works on the tunnel. 

Archive drawings from the original build in conjunction with a ground investigation has enabled a methodology and sequence of construction to be established.
