The aim of the present paper is to present a very simple and effective model, describing the long-term deformations of both interacting sub domains - the subsoil and upper-structure in a similar manner. The effectiveness of the proposed approach consists in converting the integral constitutive equations for creep in the upper-structure and consolidation of a fully saturated subsoil layer into a set of the first order differential equations. Subsequently, the algebraic incremental solution is obtained by applying Dirichlet-Prony's series for both the compliance function and degree of consolidation. The incremental method also comprises the building progress by taking into account the increments of individual segments consecutively added.
