Abstract: This paper reports on the results of a field investigation and settlement monitoring program which involves five buildings founded on shallow foundations in the sensitive clay deposits of Montreal Island (Quebec, Canada). The purpose of this paper is to provide a better understanding of the shrinking behavior of these soils. Each site has been instrumented with foundation elevation pins, ground movement plates, deep settlement points, piezometers, and aluminum tubes for the measurement of volumetric weights and water contents in the clay deposits.
