There are very many engineering projects that have taken place over the past decades or century that have improved the way we live and do things. These projects have continued to break mankind’s inborn limits. Engineering demands hard work and sacrifice. The projects listed below are a symbol of determination and progress. Below are the top 4 engineering projects of all times.
1. The Panama Canal
This canal is in the list of the top 4 engineering projects of all times because of the canal’s contribution to shipping. Built between 1904 and 1914, the canal connects 2 oceans together (Pacific and Atlantic). The canal is 77 kilometres long which makes it the longest man-made ship canal in the world. The Canal project is currently among the most challenging engineering projects to ever see the light of day. The canal had a very significant impact on shipping between the 2 oceans since it creates a route around Cape Hom.
The project involved very challenging tasks i.e. immense excavation (160 dirt trains were utilised daily and over 60,000,000 pounds of dynamite). The canal also required a serious railway system upgrade. Since opening, over 815,000 vessels/ships have used the canal making it the busiest and most important canal in the world.
2. Burj Khalifa
The Burj Khalifa is also among the top 4 civil contractor engineering projects of all times. The Burj Khalifa makes this list because it is currently the world tallest building measuring a staggering 828 meters long. The Burj Khalifa had to utilise a structural system that had never been used before to build skyscrapers. The system was developed by architects and engineers to handle the extraordinary height of the building. For better stability, the Burj Khalifa was build with 27 terraces with the core emerging into a steel spire weighing 4,000 tonnes.
Costing a record $1.5 billion to build, the Burj Khalifa definitely set new engineering records and standards. The fact that the Burj Khalifa is the tallest skyscraper in the world is an extra ordinary achievement without even considering the engineering prowess.
3. Kansai International Airport
This is another top engineering project of all times. Located in Osaka Japan, the airport is built on a manmade island which is an extra ordinary achievement in itself. The airport is the first of its kind. It was built to reduce over congestion in an old neighbouring airport. Because engineers didn’t have any space to build another airport on existing grounds, they decided to build a new island which would house Kansai International Airport on Osaka Bay.
The project is among the top engineering projects to ever see the light of day in the world because of the extraordinary challenges engineers had to overcome constructing the island i.e. massive excavation (21 million cubic meters of dirt/landfill) and overcoming risks of typhoons and earthquakes.
4. Qingdao Haiwan Bridge
Located in Qingdao, China the bridge connects two major cities in china i.e. Qingdao and Huangdao. Opened in 2011, the Qingdao Haiwan Bridge is the longest overwater Bridge worldwide covering 42.5 kilometres. The bridge shortened the distance between Qingdao and Huangdao by a record 31 kilometres.
The bridge took 4 years to be complete with a workforce of 10,000 workers including civil contractors. The Qingdao Haiwan Bridge is a magnificent engineering project consisting of a 6 lane expressway resistant to typhoons, earthquakes measuring up to 8.0 and vessel impacts of up to 300,000 tonnes. The bridge is currently the longest in the world.
