Crossrail (Elizabeth Line), London

Project aims and scopes:

Dr. Mehdi Kashani played a critical structural engineering role within the ~£19 billion Crossrail (Elizabeth Line) programme in London. His overarching scope across the project encompassed preliminary and detailed structural design, rigorous capacity assessments, and independent Category III verification for several high-value station packages. The primary aim of these engineering efforts was to ensure the structural integrity of major station boxes and cut-and-cover tunnels, validate safe construction staging, and develop alternative construction methodologies and complex temporary steelworks for deep shafts in highly restricted urban environments.

Main body of work:

Dr. Kashani’s contributions were spread across four major station developments on the Crossrail network:

Paddington Station (Package C130 - £220 million): He executed the preliminary and detailed design for cut-and-cover tunnels, station box elements, temporary works, and construction staging.  

Royal Arsenal Woolwich Station (£100 million): He conducted Independent Category III structural analysis and capacity assessments to verify the safety and resilience of the primary station box.  

Bond Street Station East Ticket Hall (Package C132 - £300 million): He performed extensive independent structural checks, which included complex load take-downs, finite-element (FE) modelling of slabs and columns, and meticulous construction stage verification.  

Farringdon Station (Package C136 - £200 million): He designed complex temporary steelworks to safely support deep shafts and assessed alternative construction methodologies to navigate the station's challenging conditions.
