Through consistent research and study, Shanghai Construction Group, builder of the Shanghai Tower, is now capable of constructing supertall skyscrapers towering to 1,000 meters, sources said.

According to a press release sent to China Daily by Shanghai Construction Group, one of its demonstration projects recently passed the acceptance check in Shanghai, marking technological breakthrough in building supertall skyscrapers by a Chinese company.

"Before the building of Shanghai's Jinmao Tower, all the key equipment for high-rise construction was purchased abroad. But after undertaking construction of the nation's tallest skyscraper Shanghai Tower, we've made a rapid progress in both experience and technology," Gong Jian, chief engineer of Shanghai Construction Group was quoted as saying by ThePaper.cn.

Shanghai's Lujiazui district, the nation's financial hub, features 235 buildings considered high-rises, and its skyline is still expanding.

The integral steel platform has overcome the shortcomings of previous construction, and through the newly developed transfer pump, ultra-high strength concrete can be delivered to the height of 620 meters by a single pump.

Shanghai Construction Group's annual R&D investment reached 2.9 billion yuan during the 12th Five-Year Plan period (2011-2015).

The world's tallest building under construction is the Jeddah Tower in Saudi Arabia. Previously known as Kingdom Tower, it is designed at a height of about 1,007 meters, nearly 180 meters higher than the world's existing tallest building Burj Khalifa.

Of the 106 buildings taller than 200 meters completed last year globally, 62 were in China, and six out of the top 10 skyscrapers in the world nearing completion in 2016 were in China, according to a report from the Council on Tall Buildings and Urban Habitat.
