As re gards the scope, and magnitude of the project, the abstacles to be overcome, and the speed of its ne- complishment, the completion of the Dnieper. River dam and power plant constitutes one of the greatest achievements of modern engineer- ing. Both the dam, the last batch of concrete in which was placed on March 28 of this year, and the power plant, which gave its first commercial power on May 1, were completed about six months ahead of schedule. The cost of construction of the power plant and dam was 8110 million, and together with the complex of industrial enterprises now rising around it and the con- struction of the socialist city, the project will involve a total cost of 820 million roubles (about $420 million). At times as many ns 50,000 workers were employed on the project, the preliminary work of which was begun in March, 1927.
