We present a supersymmetric TeV-scale theory with a matter content filling complete E₆ multiplets arising from an orbifold construction with E₆ constituting the gauge group in the bulk of the extra dimensions. The main focus lies on the structures linking the Lagrangian parameters at the orbifold compactification scale to the TeV-scale spectra as well as their algorithmic realization in the automated spectrum generator EXSPECT. Among the most interesting features in this setup are the multi-scale gauge coupling unification scheme, top-bottom Yukawa unification, and its implications on the vacuum structure breaking the electroweak symmetry. In order to find solutions on the high-dimensional space of input parameters incorporating the aforementioned aspects, we use Monte-Carlo Markov-Chain techniques. The first results obtained with this method as well as a phenomenological study of the production of the heavy neutral gauge boson at the LHC for these cases will conclude our discussion.
