Location: Frankfurt, Hessen, Germany Client: State of Hessen and German Rail Project Scope:
Management: Project, Program, Integration, and Configuration and Language support
Note: Construction Plans: Reinforcement, formwork, electrical, HVAC, fire, drinking water plans
This project cost: 250 million USD with two tunnels at Frankfurter Kreuz: Curve Sportfeld (1,886m) and Curve Zeppelinheim (1,632m), both are four rail tunnels mounted directly on concrete and are approximately 11.5 and 12.5 meters width.
The tunnel works ended on 30 November 1998. A prefabricated plinth was installed for time advantages (on rail) in schedule in parallel roadwork was completed, only 3 to 6 foot of backfill was completed for the tunnel, the walls and floor was done using the jet grouting process also time saving and for stabilization the ground. Rail: 9600m track (6940m in tunnel) with four points were created, 1995 the contract to lay and fix the track was awarded and the tunnel was transferred to a traditional ballast tunnel.
On March 25, 2001, the tunnel hit the headlines when the driver of the ICE 725 stopped the train in the tunnel and went into the dining car to make a 20-minute break
Information: Max radius of curvature is at 1000m Elevation max 160mm Longitudinal max inclination 30.378‰ Track distance: 4.00 to 4.70m
