The Most Impressive Civil Engineering Structures

IES is proud to offer comprehensive civil engineering consulting.  From public and private site development, rehabilitation of water and piping systems and roadway reconstruction, we address design needs as well as the development requirements to create the best project possible for our clients.  As civil engineers, we tip our hats to some of the most impressive civil engineering structures in history.

Qingdau Hawain Bridge: Qingdau, China, 2011
The longest bridge in the world, the Qingdau Hawain Bridge reaches over 26 miles, connecting the city of Qingdau to the suburbs of Huangdao across Jaiozou Bay.  It took four years and 10,000 workers to build, three million cubic feet of concrete and 450,000 tons of steel.  It can withstand typhoons, large ship collisions and earthquakes up to 8.0 on the Richter scale.

Dubai Tower (Burj Khalifa): Dubai, UAE, 2010
This tower is the tallest free standing structure in world coming in at 2,717 feet. It boasts 163 floors and 27 terraces. It took 22 million man hours to build and can withstand winds up to 99 miles per hour.

The English Channel Tunnel: Strait of Dover, 1994
At 31 miles long and 250 feet deep, this tunnel is the longest underwater tunnel in the world.  It connects England and France and took six years to build and the labor of 13,000 engineers, technicians and construction workers.

The Golden Gate Bridge: San Francisco, CA, 1937
This bridge has over 27,000 strands of cable that when put together are over 80,000 miles long.  It is built to withstand high winds and earthquakes.

Hoover Dam: Colorado River, AZ, 1936
The dam is almost 600 feet deep at its base and 45 feet deep at the rim.  It generates enough power each year for 1.3 million people in Nevada, Arizona and California.  Its success had the greatest impact for people in the 20th century.

Panama Canal: Panama, 1914
This waterway is 47 miles long and allows ships to cross oceans between North and South America, shortening the original trip by 9,000 miles. Its “Lock System” requires ships to be lifted on one side and lowered on the other until it reaches the summit.  15,000 ships cross this canal every year.

The Brooklyn Bridge: New York, 1883
The Brooklyn Bridge was the longest suspension bridge in the world at the time it was built and the first to use steel for its wire. The project was also the first to use underwater explosives. Today, 144,000 vehicles cross the bridge on a daily basis.

Aqueduct of Segovia: Segovia, Spain, 50 A.D.
This structure was designed to move water from the Funete Fria River to the La Acebeda region. It is 9.3 miles long and boasts 167 arches that are all over 29 feet tall.  It is made of 24,000 granite blocks (placed without mortar) and was so well preserved that it is still in use today.

Great Wall of China: China, 475 B.C.
The wall is made out of several smaller walls that were joined over the past 2,000 years to make the wall we recognize today.  It is 5,500 miles long and was originally built to protect China from the Huns.

Great Pyramid: Giza, Egypt, 2504 B.C.
This great structure is made out of 2.3 million blocks of stone, each block weighing 2.5 tons. It is 450 feet tall and over 750 feet wide. It was the tallest manmade structure in the world for almost 4,000 years.
