This paper deals with the problem of minimizing the present worth of expenditures for the expanding the capacity of a communications network in the face of an increasing demand for service. It is assumed that any economy of scale effects are dominated by savings due to expenditure deferral. A strategy is proposed that defers new construction of facilities by heuristic routing around exhausted facilities. Network solutions obtained by the deferral heuristic applied to a small prototype network compare favorably with exact solutions obtained by solving the underlying mixed integer LP.
