We analyze the consistency of the ADM approach to KK model; we prove that KK reduction commutes with ADM splitting. This leads to a well-defined Hamiltonian; we provide the outcome. The electromagnetic constraint is derived from a geometrical one and this result enforces the physical meaning of KK model. Moreover we study the role of the extra scalar field φ we have in our model; classical hints from geodesic motion and cosmological solutions suggest that φ can be an alternative time variable in the relational point of view. © Società Italiana di Fisica.
