Hoover Dam. Builders and construction

The construction of the Hoover Dam was a very complex engineering challenge. First, it was necessary to strengthen the walls of the canyon, exposing the rock formations on which the concrete arch of the dam would later rest, while at the same time protecting those working below from falling stones (the main cause of accidents at the construction of the dam). These works were carried out by climbers using jackhammers and dynamite.

In order to drain the site of the future construction site, it was necessary to divert the waters of the Colorado River. Two temporary, so-called “caisson” dams were built, located above and below the dam construction site. Four huge tunnels were drilled into the rocks of the canyon, two from the Nevada side and two from the Arizona side. The diameter of the tunnels was about seventeen meters, and after facing with concrete – about fifteen meters, the total length of the tunnels of the Hoover Dam – about five kilometers. The construction of the tunnels began in May 1931, and already in November 1932, a river was directed into the “Arizona” tunnels (“Nevada” ones were spare, in case of floods). After the construction of the dam was completed, the tunnels were partially drowned out, and partially used to release water.

In June 1933, a year and a half earlier than planned, concrete work began on the construction of the Hoover Dam. Two factories were built near the construction site to make the vast quantities of concrete in Nevada. Delivery of concrete was carried out in special containers with a volume of more than six cubic meters, each of them weighed about eighteen tons when filled. These huge buckets were transported to the canyon on special wagons, and then transported to the place of unloading using ropes.

During the construction of the Hoover Dam, innovative solutions were widely used. So, for example, in order to avoid cracking of concrete when it hardens, the construction of the dam was not monolithic, but consisted of many columns, between which pipes were laid. River water was supplied through pipes, cooled by powerful refrigeration units. After the concrete columns hardened, the gaps between them were filled with mortar.

In total, more than two million four hundred and eighty thousand cubic meters of concrete were used to create the Hoover Dam. Another eight hundred and fifty thousand cubic meters went to the construction of a power plant and other structures of the dam complex. At the time of construction, it was the largest man-made structure in the world.

The architectural solution of the buildings of the dam was made by Gordon Kaufmann in the Art Deco style popular at that time (in which, in particular, the famous New York skyscrapers Chrysler Building and the Empire State Building were built). In addition, the motifs of the Navajo and Pueblo Indian peoples living in this region were used in the design. It is interesting that clocks are installed on each of the two towers of the Hoover Dam, one of which shows the time of the US Mountain Time Zone, in which the state of Arizona lives, and the other in the Pacific Time Zone, to which the state of Nevada belongs .
