As
The Conco Companies have been in involved in many of the largest, most
distinguished projects in the Western United States, we are always interested
to learn more about some of the megaprojects going on across the globe. Here is a quick look at a few of them.
Originally
opened in 1914, the expansion of the Panama Canal is expected to be finished in
2016 at the cost $5.25 billion and 11 years to build. The project consists of a new 3.8-mile long
channel for the new locks and is estimated to have required 4.4 million cubic
meters of concrete. This new phase of
the canal was necessary to widen and deepen the channel to better accommodate
modern ships which have grown in size.
Another
impressive project is the world’s largest dam in China that took 17 years and an
estimated $30 billion to build. The
Three Gorges Dam is built entirely of steel (510,000 tons) and concrete and is
a hydroelectric dam that spans the Yangtze River by the town of Sandouping,
located in Yiling District, Yichang, Hubei province, China. The dam measures 595 feet tall, 131 feet wide
and over 7,600 feet long. There are 32
main turbines that produce the electricity.
One
mega-project from right here at home is the recently completed east span of the
San Francisco-Oakland Bay Bridge, which holds the Guinness World record for the
widest bridge in the world. It is
estimated to have a cost of 6.4 billion and is the most expensive public works
project in the history of California.
The east span of the bridge is 258.33 feet wide and consists of 10
general purpose lanes.

contractors in the Western U.S. and offers a wide range of quality services and
