  The gauge coupling unification is one of main motivations in the split-SUSY
scenario, and the existence of the grand unified theories (GUTs) is assumed. We
examine how to realize split-SUSY mass spectrum in the context of GUTs and find
that the construction of split-SUSY GUTs is by no means straightforward. With
R-symmetry breaking sources in the GUT sector,
  GUT particles play a role of the messengers in the gauge mediation scenario
and their contributions to gaugino masses can be sizable. We find the upper
bound on soft scalar masses of
  O(10^{10}) GeV from consistency for constructing the split-SUSY GUT. Also, we
discuss the attempt to construct R-symmetric GUT models.
