Base DTM Map Cross Sections Road/Rail Design Setting Out Deformation Monitoring Drainage Manager Render The tunnel module is designed to check the clearances for the final tunnel alignment. Calculates over break and under break volumes, along with a range of setting out options for laser guidance and tunnel floor intersection points. • Generate shapes which can be hung from an alignment (tunnel design profile or a trains kinematic envelope) • Compare two alignments (tunnel design and laser) to determine offsets and height differences at required chainages • Compare the as-built tunnel position compared the tunnel design alignment and redesign the alignment if required to put it back on track • Perform a tunnel wriggle to highlight over/under break volumes, clearances and pinch points • Print reports showing maximum and minimum clearances together with over/under break and pinch points • Monitor as-built tunnel sections • Print monitoring reports showing movement over time
