Chartered Engineer with principal experience in design and construction of tunnels and underground structures in both soft ground and fractured rock masses.

Experience includes independent design, verification and construction of various structures in large civil and mining infrastructure design and construct projects.

Expertise includes analysis of tunnels and underground structures through rock and soil using advanced 2D and 3D numerical modelling; SCL (NATM) tunnel design and construction for large and complex urban station upgrade schemes; preparation of ‘for construction’ potential damage assessments for complex SCL and traditional timber-work drives adjacent to large cast iron platform tunnels, and design of large diameter tunnels in shallow urban environments.

Experienced in design development, detailed design and production of ‘for construction’ design documentation. Site experience includes over 3 year of providing site support and design validation during construction of SCL (NATM) and TBM tunnel projects.

Over 13 years of experience in the design and construction of tunnels and underground structures with a recent focus on SCL tunnelling.

Experience includes advising on design and construction related issues for complex SCL tunnelling projects in London, as a specialist sub-consultant, including:

  • Crossrail C121
  • Bond Street Station Upgrade
  • Tottenham Court Road Station Upgrade

Considerable experience in undertaking potential damage assessments for SCL tunnelling adjacent to live London Underground running and platform tunnels, followed by design verification through monitoring and feedback during construction.

Responsible for development of all potential damage assessments on London Underground deep tube tunnels and deriving trigger limits during the design stage for the Victoria Station Upgrade project.

Recently responsible for specifying installation of specific instrumentation and monitoring on cast iron London Underground segmental tunnels and monitoring their response during adjacent SCL or handwork excavations.

Also responsible for undertaking design optimisation during construction leading to development ‘propless’ openings, four of which have been successfully constructed on the Victoria Station Upgrade project.

Site experience includes working with contractors and designers on-site in design and construct as well as an alliance environment.

Extensive research experience in both application and academic aspects of geotechnical engineering, producing numerous publications in peer reviewed conferences and journals.
