Project Spotlight: Hangzhou Bay Bridge

The longest ocean-crossing bridge in the world, the Hangzhou Bay Bridge is an S-shaped stayed-cable bridge with six lanes in both directions that shortens the distance between Shanghai and Ningbo by 120 kilometers. The 36 kilometer long bridge required a great number of new techniques, new materials, new equipment and new theories due to the large scale and design of the project. It took close to 600 experts and a total of nine years to design the bridge. The Hangzhou Bay Bridge is expected to boost the economic development of the Yangtze River Delta, also called the Golden Industrial Triangle. Work on the bridge began in June 2003 and was completed in June 2007. The bridge was opened to the public in May 2008 and carried about 50,000 vehicles per day in its first year of operation. The total project cost was approximately $1.5 billion.

Towering majestically on Taiwan’s skyline, the Taipei 101 was the first world’s tallest building completed in the 21st century and remains the first building in the world to break the half-kilometer mark in height. It was surpassed by Burj Khalifa in Dubai in 2010 though it remains a significant structure globally. Completed in 2004, the building stands at 508-meters and has 101 floors. A prominent icon in Taiwan, fireworks launched from the tower on New Year’s Eve has become an international broadcast and it is featured frequently in international media.

These gifts have an interesting engineering theme and would make excellent gifts for engineers

It is that time of the year again, when gift-giving becomes a requirement at most social functions. We therefore feel obligated to continue our gifts for engineers articles, a series of articles intended to demystify the peculiar tastes of engineers. From books to electronics this list is a continuation of what we feel if a public service for the benefit for all. The following list provides a delightful collection of gifts that engineers will appreciate the subtle engineering themes.

Civil Engineering Landmark # 1: Tehachapi Loop

Civil Engineering Landmark # 1: Tehachapi Loop

Built from 1874 to 1876, The Tehachapi Loop was built to connect California’s fertile San Joaquin Valley with the then small agricultural town of Los Angeles on California’s southern coast. Originally, the plans mapped out indicated that the Tehachapi Line would bypass Los Angeles and instead go southeast through the Mojave Desert to Yuma, Arizona, and all points east. Eventually state politics overruled the Southern Pacific’s decision, which was the company that monopolized railroad transportation in California at that time.

Renewability

Renewability

The world “renewable” has quickly become a synonym of words like “clean”, “environmentally friendly” and “sustainable” in our language. Even the companies and governments have used it with commercial, informative and even propagandist goals. The truth is that “renewable” stuff is part of contemporary life since some years ago, especially when energy is involved.
