Abstract

A wealth of litigation-related information was available at a development where swelling soil conditions exist, including some soil suction measurements, extensive swell test results, and level surveys of building movement obtained at various points in time, providing information for evaluation of methods for estimating remaining heave. The development included 34 residential buildings constructed over a 6-year period, soon after which ground heave and associated structural movement occurred at several of the buildings. The remaining heave computations made by the writers are based on application of net partial wetting factors (NPWF) to fully-wetted swell test results, as proposed by Houston and Houston (2017). Comparisons and discussion of other remaining heave computation methods are presented.
