The scheme comprises the refurbishment of a former electricity substation within central London for commercial use at Shorts Gardens. The existing building contained a substantial basement and directly overlies the Elizabeth Underground Line.
We were required to design and carry out a ground investigation to characterise geotechnical and hydrogeological conditions at the site. The investigation was also required to confirm the foundation arrangements of the existing building.
Following the ground investigation, we were also commissioned to undertake ground movement analyses to assess the potential impact on the underground line. We initially consulted with Crossrail to agree on modelling methodology and avoid potential abortive work.
The presence of the underground tunnel was a significant investigation and development constraint. Through early liaison with the tunnel owners and detailed ground movement analysis, Soiltechnics were able to assist the designers to get approval for the scheme.
