The SPARC project is a collaboration between ENEA and INFN on an R&D activity oriented to the development of a high-brightness photoinjector to drive SASE FEL experiments. Tolerances for the alignment of the accelerator components were very tight and it has been quite a challenge to obtain them using standard techniques and instruments such as optical levels, theodolites and laser trackers. A description of the alignment and fiducialisation procedures of the accelerator components is presented.
