17 pages, no figures, LaTeX<br/>We provide a space-time covariant Hamiltonian treatment for a finite-range gravitational theory. The Kuchar approach is used to demonstrate the bimetric picture of space-time in its most transparent form. This Hamiltonian formalism is applied for the straightforward realization of the Poincar�� algebra in Dirac brackets. It uncovers the simplest form of the Poincar�� generators expressed as spatial integrals of ultralocal quantities constructed pure algebraically by means of the two space-time metrics.<br/>
