Given a relatively projective birational morphism f: X→ Y of smooth algebraic spaces with dimension of fibers bounded by 1, we construct tilting relative (over Y) generators T X, f and S X, f in D b (X). We develop a piece of general theory of strict admissible lattice filtrations in triangulated categories and show that D b (X) has such a filtration L where the lattice is the set of all birational decompositions f: X→ g Z→ h Y with smooth Z. The t-structures related to T X, f and S X, f are proved to be glued via filtrations left and right dual to L. We realise all such Z as the fine moduli spaces of simple quotients of O X in the heart of the t-structure for which S X, g is a relative projective generator over Y. This implements the program of interpreting relevant smooth contractions of X in terms of a suitable system of t-structures on D b (X).
