The ATLAS Experiment came as a marriage from two Proposals (ASCOT and EAGLE), both of them emphasizing the need to have a toroidal field to be able to measure µ's over a large rapidity range. The outcome, after many discussions was the ATLAS proposal, however many changes needed to be introduce, in order to achieve an Spectrometer that could not only work reliable for more than 10 years, but also to be able to provide a very precise measurement of the Higgs Boson mass at the level of 0.4‰, which demands knowing individual detector positions in space to the level of 0.1mm in a volume of 45X25X25m³. The presentation will describe how this was achieved with a strong motivation of a collaboration that included 500 Physicists from 45 Institutions.
