The Millennium City will soon boast of a first-of-its-kind intra-city Metro service, but construction work on the project has already scaled new heights.
The promoter firm, Rapid MetroRail Gurgaon Limited (RMGL), has constructed two 24-metre-high pillars near the Sikanderpur Metro, making them the tallest built for any Metro network in India.
The Delhi Metro Rail Corporation's tallest pillar is 21-metres-high at Dhaula Kuan.
Both pillars are located at a junction where public and private transport will be operational at four levels in the form of a proposed underpass, a flyover, the Metro network and the existing road level.
The 5.1-km intra-city link has been privately-funded by the RMGL in DLF City 2 and 3.
He added that the firm used a technology that involves steel piles and timber lagging, often referred to as "Berlin Wall".
Also known as king piles or soldier piles, the technique has been in use since the late 18th century in metropolitan cities such as New York and London.
"Since an underpass will be built at this location later, we had to construct the pier under the base of the existing road. To ensure speedy completion of work, we had to go for soldier piling so that traffic movement was not disturbed," said Sarvesh Tiwari, the RMGL spokesperson.
