Abstract: Dimension-5 corrections to the gauge kinetic term of Grand Unified TheoriesGUTs may capture effects of quantum gravity or string compactification. Suchoperators modify the usual gauge coupling unification prediction in acalculable manner. Here we examine SU5, SO10, and E6 GUTs in the light ofall such permitted operators and calculate the impact on the intermediatescales and the unification programme. We show that in many cases at least oneintermediate scale can be lowered to even 1-10 TeV, where a neutral Z- andpossibly other states are expected.
