Six Companies, Inc., did much of this work, but it discovered that such a large refrigeration project was beyond its expertise. Hence, the Union Carbide Corporation was contracted to assist with the refrigeration needs.
Six Companies, Inc. was contracted to build a new town called .Boulder City for workers, but the construction schedule for the dam was accelerated in order to create more jobs in response to the onset of the Great Depression, and the town was not ready when the first dam workers arrived at the site in early 1931. During the first summer of construction, workers and their families were housed in temporary camps like Ragtown while work on the town progressed.^ Hotels Near Boulder City-Hoover Dam Museum - boulder city Nevada hotels .

Discontent with Ragtown and dangerous working conditions at the dam site led to a strike on August 8, 1931. Six Companies responded by sending in strike-breakers with guns and clubs, and the strike was soon quelled. .But the discontent prompted the authorities to speed up the construction of Boulder City, and by the spring of 1932 Ragtown had been deserted.^ Hoover Dam - Boulder City, NV Now in the UK!

While working in the tunnels, many workers suffered from the carbon monoxide generated by the machinery there.

To protect the construction site from flooding, two cofferdams were constructed. Construction of the upper cofferdam began in September 1932, even though the river had not yet been diverted. A temporary horseshoe-shaped dike protected the cofferdam on the Nevada side of the river. .After the Arizona tunnels were completed, and the river diverted, the work was completed much faster.^ A soaring 1,900-foot span across the gorge created by the Colorado River on the Arizona-Nevada border should be completed t..

  • Hoover Dam - Boulder City, NV 9 February 2010 14:38 UTC www.yelp.com [Source type: General]

For the dam to rest on solid rock, it was necessary to remove all the riverbed's accumulated erosion soils and other loose materials until sound bedrock was reached. Work on the foundation excavations was completed in June 1933. During excavations for the foundation, approximately 1,500,000 cubic yards (1,150,000 m3) of material was removed. .Since the dam would be a gravity-arch type, the side-walls of the canyon would also bear the force of the impounded lake.^ Boulder City NV Group Hotel Rates Hoover Dam, once known as Boulder Dam, is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Arizona and Nevada.

.Therefore the side-walls were excavated too, to reach virgin (un-weathered) rock which had not experienced the weathering of centuries of water seepage, wintertime freeze cracking, and the heating/cooling cycles of the Arizona/Nevada desert.^ The dam itself is pretty massive and cool since it covers two time zones (Nevada and Arizona).

In March 1932, work began on lining the tunnels with concrete. First the base, or invert, was poured. Gantry cranes, running on rails through the entire length of each tunnel were used to place the concrete. The sidewalls were poured next. Movable sections of steel forms were used for the sidewalls. Finally, using pneumatic guns, the overheads were filled in. .The concrete lining is 3 ft (0.91 m) thick, reducing the finished tunnel diameter to 50 ft (15 m).^ When you see earthquake monitoring equipment and you are inside almost 660 feet of thick concrete tunnel, it doesn't matter what religion, if any, you are.

The resulting stresses would have caused the dam to crack and crumble.[17] To solve this problem the dam was built in a series of interlocking trapezoidal concrete pours. To further cool the concrete each form contained cooling coils of 1 inch (25 mm) thin-walled steel pipe. .River water was circulated through these pipes to help dissipate the heat from the curing concrete.^ So someone came up with the idea to put metal piping between the blocks of cement and running cold water through them to chill and hence solidify the cement.

Spillways

The dam is protected against overtopping by two spillways. The spillway entrances are located behind each dam abutment, running roughly parallel to the canyon walls. The spillway entrance arrangement forms a classic side-flow weir with each spillway containing four 100 ft (30 m) long and 16 ft (4.9 m) high steel drum gates. Each gate weighs five-million pounds and can be operated manually or automatically. Gates are raised and lowered depending upon water levels in the reservoir and flood conditions. The gates cannot completely stop water from entering the spillway but help maintain an extra 16 ft. of lake level. [33]
.Water flowing over the spillways drops sharply into either of 600 ft (180 m) long, 50 ft (15 m) wide spillway tunnels before connecting to part of the construction diversion tunnels, and reenters the main river channel below the dam.^ Before a single gallon of cement was poured, about two years were spent creating infrastructure and roads for this massive project, raising a new town to house workers, and building huge earthen dams and diversion tunnels to keep the Colorado river away from the site.

This complex spillway entrance arrangement combined with the approximate 700 ft (210 m) elevation drop from the top of the reservoir to the river below is a difficult engineering problem and poses several design challenges. The overall spillway capacity was empirically verified in post construction tests in 1941. This test also showed that the spillway tunnels could be damaged from cavitation created by the high velocity flow when running near full volume. .After further damage was incurred during use in six weeks in the summer of 1983, the tunnel linings were repaired and the spillway tunnel design was modified to minimize cavitation potential.^ You also get to see one of the bypass tunnels that were used to divert water around the dam site during its construction.
