Construction Simulation of the Main Earth Dam at Manicouagan 3

This paper describes the computer model developed to simulate construction of the eleven million cu yd gravel dam at Manic 3, and outlines the results obtained. Construction of the dam is a complex task influenced by many random events.

Manic 3 is part of Hydro-Quebec's Manicouagan-Outardes hydroelectric development, which will ultimately comprise seven power stations with a combined capacity of 5.5 million kW.

Before simulation was introduced, it was extremely difficult to solve the many problems involved in choosing and utilizing equipment, obtaining accurate time and cost estimates, and formulating realistic production schedules.
