Chief Minister N. Chandrababu Naidu set the ball rolling for the construction of the permanent Secretariat and Heads of Departments complex by laying the raft foundation at Kondamarajupalem on Thursday.
The event marks a major milestone in the capital city project a few months ahead of the general elections. The complex, designed for four towers of 40 floors each and another with 50 floors, will be the first permanent structure in the administrative city in 1,375 acres.
A massive 57,000 cubic metres of concrete will go into the foundation for the towers, the tallest of which will rise 225 m. The uniqueness of the foundation is the that entire volume of 11,000 cubic meters of concrete per raft would be poured non-stop for 72 hours. A raft foundation comprises large concrete slabs evenly spread under the entire buildings against the conventional strip and trench footings. The project cost is estimated at ₹3,500 crore and is being implemented by L&T, the Shapoorji Pallonji Group and the Nagarjuna Construction Company.
