Abstract
Using punctual gluing of -structures, we construct an analogue of S. Morel's weight truncation functors (for certain weight profiles) in the setting of motivic sheaves. As an application we construct a canonical motivic analogue of the intersection complex for an arbitrary threefold over any field . We are also able to recover certain invariants of singularities motivically.
