Requirements analysis

Geocon already provides the client with recommendations during the design of the segments’ deck configuration.


Prior to immersion, the position of the measurement points in the tunnel segment itself, on the roof of the unit and in the survey mast and shaft need to be effectively coordinated with the other elements installed in the segment.

In addition, the success of a segment immersion relies on determining the right method for aligning the walls, correctly measuring the segments’ supporting structures, the position of the temporary tile supports used during immersion and checking whether the plates of the immersed joint socket are level.
