The evolution of self-consistent beyond-mean-field techniques (BMF) based on the Gogny interaction to better describe nuclear spectra is presented. In particular, different implementations of symmetry restorations and configuration mixing within the generator coordinate method are discussed. Finally, the results for excitation energies in the magnesium isotopic chain from N = 8 to N = 28 are provided as an example of the performance of those different many-body methods.
