Engineering Milestone: World's Largest Building

This is a continuation of a series of articles that tackles different engineering achievement, from world’s tallest building, longest bridge, biggest building, and the likes. Now let’s talk about the world’s largest building (Largest floor space).

China is now on a construction boom, infrastructures are popping up like mushrooms. As its economy grows, they have more resources to build magnificent buildings. Last July 01, 2013, the New Century Global Center was officially opened. It is 100 meters high, 500 meters long, and 400 meters wide with 1, 700, 000 square meters (1.7 sq km) of floor space. To put on perspective its size, it is as large as 329 football fields, it could hold 20 Sydney Opera Houses, and it is three times the size of Pentagon Building. And actually it’s just slightly smaller than Monaco (2 sq km).

The construction was started on 2010 and was finished on 2013. It’s a 18-story, glass-and-steel frame structure that sits above a new subway station in Chengdu, a Sichuan province city of more than 14 million and one of China's fastest-growing megalopolises.

Inside New Century Global Center are shopping malls, offices, 2 five-star 1000-room hotels, conference rooms, a university complex, two commercial centers, an IMAX cinema, a "Mediterranean village", a pirate ship and skating rink. The centerpiece of the building will be a 5,000 m2 (54,000 sq ft) artificial beach that can accommodate 6,000 people; a giant 150 by 40 m (490 by 130 ft) screen will form the horizon and offer sunrises and sunsets. 

I’m pretty sure that in the distant future, construction of this kind of building will be more often, not only in China but in other countries too.

Engineering Milestone: World's Longest Bridge of Any Type

This is a continuation of a series of articles that tackles different engineering achievement, from world’s tallest building, longest bridge, biggest building, and the likes. Now let’s talk about the world’s longest bridge.

With the advancement of technology and machinery, building something big and long now seems to be less difficult. With this, engineers and architects were able to build majestic infrastructures around the globe. And one kind of that majestic infrastructure is the Danyang Kunshan Grand Bridge in China.

According to Wikipedia, a bridge is a structure built to span physical obstacles such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. There are many different designs that all serve unique purposes and apply to different situations. Designs of bridges vary depending on the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it.

There are several type of bridge, this our:
  • Beam Bridge
  • Truss Bridge
  • Cantilever Bridge
  • Arch Bridge
  • Tied Arch Bridge
  • Suspension Bridge
  • Cable-stayed Bridge
  • Double-Decked Bridge
  • Viaduct

Danyang Kunshan Grand Bridge falls into viaduct category, which is composed of several small spans for crossing a valley or a gorge. The bridge is 164, 800 meters (164.8 km) long. It has a main span of 80 meters (260 ft) and it runs through land and over water. Actually the world’s longest bridge over water the Qingdao Haiwan Road Bridge is just a part of Danyang Kunshan Grand Bridge. Qiandao Haiwan Bridge (Jiaozhou Bay Bridge) is 26.7 km long.
Danyang Kunshan Grand Bridge is located on the rail line between Shanghai and Nanjing. Its construction started on 2006 and was completed on 2010 and the official opening was on 2011, the construction employed 10, 000 workers and costs around $8.5 billion. The main purpose of the bridge is to solve the railway traffic on the area.


The high volume of workers is partially caused by the 450, 000 tons of steel structure used in the construction. Chinese officials stated that, the Danyang Kunshan Grand Bridge can withstand strong typhoons, magnitude 8 earthquakes and an impact that is equal to a 300, 000 ton vessel.

With its massive length, Danyang Kunshan Grand Bridge is truly an Engineering milestone.
