Liebherr Drilling/Piling Rigs on Crossrail
Various Crossrail sites, London, UK · 2009-2022 (Crossrail construction period) · £18.9bn (Crossrail project total)
The judgement call
Account-gated at launchCrossrail involved extensive deep foundation work for its numerous stations, shafts, and portals. While specific models like the LB 44 are not explicitly mentioned in public records for Crossrail, Liebherr is a major supplier of deep foundation equipment, and it is highly probable that various Liebherr drilling and piling rigs were utilized by the main contractors to execute the complex deep foundation works required for the project.
Key engineering challenges
Installing deep foundations in complex urban geology and congested environments. - Managing ground conditions and minimizing settlement in sensitive areas. - Executing various drilling and piling techniques to support underground structures.
