The High Speed Two (HS2) railway is currently the largest planned infrastructure project in Europe. For the design of high speed rail tunnels additional aerodynamic aspects need to be taken into account where standards & requirements are currently being developed worldwide in order to ensure the design meets environmental & performance requirements. Underground structures form a significant part of the scheme: Phase 1 of the route has 12 tunnels & 2 major box structures which provide about 21% of the route length; and Phase 2 of the route has 10 tunnels which provide about 7% of the route length. The underground structures and the expected ground & groundwater conditions are described. In addition, for such a major project, robust organisational methods and management procedures are required to control schedule, cost and quality goals for the preliminary design of the underground structures and provide input into the environmental statement.
