Abstract	Several scenarios are considered for the upgrade of the LHC insertions in view of increasing the luminosity beyond 1034 cm-2s-1. In the case of “quadrupole first” option, superconducting low-b quadrupoles with apertures in the range of 90-110 mm are required in view of increased heat loads and beam crossing angles. We present possible low-b quadrupole designs based on existing Nb$_{3}$Sn and LHC NbTi superconductors, present scaling laws for the magnet parameters and discuss relative advantages of the underlying triplet layouts.
