For several years, South Africa has battled with its high emissions of greenhouse gases (GHG). The country has an abundance of coal reserves, which it relies on heavily for energy. Another major contributor of GHG is the industrial sector which is fundamental in the country’s economic activities.
Engineers are often prone to making mistakes. That is why we constantly have to check and double-check everything that we do. It is this type of keen focus on what we do that allowed generations of past engineers to create some of the most remarkable engineering projects. However, details are sometimes overlooked, numbers misrepresented or even units misread. While some of these mistakes are miniscule and can be corrected, history has witnessed some colossal oversights that led to huge disasters and in some cases, popular travel destinations.
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.

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.
