Abstract

Foundation problems during building construction may cause important structural and

nonstructural damage, and compromise the building serviceability. This paper presents a case study of a jack-
assisted leveling process implemented on a 17-story reinforced concrete building that suffered important

differential settlements during its construction. It is the first time a leveling solution for just a group of piles is
implemented, since previous studies considered intervening all foundation piles. The procedure consists on
cutting a small slice of the piles in the unsettled side of the building, equivalent to the necessary descent for
leveling the settlements in the opposite end, and lowering the unsettled part by a controlled maneuver with
hydraulic jacks. Prior to its execution, a numerical model was developed for predicting the effectiveness of the
descent maneuver indicating that the leveling process would correct the tilt of the building. The solution was
successfully implemented and the building is now in service.
