The European XFEL is an X-Ray Free-Electron Laser with a wavelength between 5 and 0.05 nm and a repetition rate of 27000 flashes per second. Civil construction started in 2009. As of 2017 the Accelerator and parts of the Undulator section are already commissioned. This presentation overviews the geodetic work during the construction phase, like fiducialization and alignment of components. The creation of the geodetic tunnel reference network is shown, as well as the merging with straightness information introduced by a novel "Straight Line Reference System" (SLRS), that was developed by the DESY alignment group.
