Finally, designs for the administrative structures in Amaravati submitted by architects Normon and Fosters have been approved. It is expected that the tender process for construction of the buildings will be started by end of April. The architects have suggested five diagrid frame skyscrapers – one of 46 floors and four of 40 floors each. The diagrid (a portmanteau of diagonal grid) is a framework of diagonally intersecting metal, concrete or wooden beams that is used in the construction of buildings and roofs. It requires less structural steel than a conventional steel frame. Hearst Tower in New York City is constructed using diagrid framework which used 21% less steel than normally required. Incidentally, Hearst Tower was designed by the architects Normon and Fosters.
According to the final design and the plan, the Chief Minister’s Office will be spread across the entire 46th floor of the first tower with a 360 degree view of Amaravati. The tower will also have a helipad. While the legislative complex will have a futuristic looking tower design, the High Court building will be like a Buddhist stupa.
Each tower will have over 25 lakh sq feet office space. The five towers will house offices of secretaries of departments alongside the respective minister’s chambers, and offices of heads of departments.
