Abstract
The tunnelling work, for a particle accelerator, must be carried out within very strict and tight tolerances. The CERN Applied Geodesy Group has the task to regularly control the geometry of the galleries and caverns constructed for the LEP project. For this purpose, different means and methods have been developed and implemented, related to the link between the surface and underground geodetic networks, the guiding control with accurate gyro traverses and the check of cross sections with photoprofiling or profile scanners. Instruments and methods are described by the authors and the results presented.
