Construction of Hoover Dam - An Engineering Wonder

COURSE NO: B07-001
PDH CREDIT: 7
COURSE PROVIDER: Allen Hughes, P.E.
Construction of Hoover Dam - An Engineering Wonder
Course Highlights

This online engineering PDH course analyzes the construction of Hoover Dam from a historical perspective. The course document provides written and photographic presentation of the construction of Hoover Dam.

 

The construction project included a combination of unprecedented logistical projects, some of which were significant projects in their own right. The dam site was chosen in a desolate area of desert on the Nevada/Arizona border where with no existing infrastructure. A city to house over 5,000 workers, railroads, roads, shuttle vehicles for workers, electric power supply, pedestrian bridges and cable trolleys were just some of the infrastructure that had to be built just to start preparing the site. To begin construction of the dam, an earthen diversion dam, a coffer dam at the downstream side of the dam, rock scaling, and a short railroad in the canyon floor were some of the tasks to be completed.

 

Depending on where they are counted, fatalities range from 96 to 112. Of the recorded fatalities, two of them stand out. The first site fatality occurred in 1922 when J.G. Tierney fell from a geologic survey barge into the Colorado River and drowned. Thirteen years later, to the day, Patrick W. Tierney, J.G.’s son, fell from the intake tower and drowned. Patrick’s death was the last fatal accident related to construction of Hoover Dam.

 

The grand scale of Hoover Dam is apparent by observing the completed dam and power plant. Less apparent, but just as impressive is the scale of the collective cooperation between, city, state, and federal government agencies and newly formed regional basin authorities and joint ventures between competing corporations.

 

This 7 PDH online course is intended for civil, structural, mechanical and electrical engineers, surveyors and planners who are interested in a historical perspective of the construction of Hoover Dam.
