Among the ideas adopted by CWG organisers was the imported, dust- and fire-proof roof that has been used in the Ranchi stadium, which boasts a seating capacity of 35,000.

To host all the athletics events, apart from the opening and closing ceremonies, the main stadium occupies pride of place in the 275 acres (111 ha) Mega Sports Complex.

With its many elliptical pylons and ramps that lead to the upper tiers, it adds to the futuristic look of the area that also houses seven smaller stadiums.

Designed by Australian firm MakMax Australia, the 12,950 square metres (139,400 sq ft) roof material was imported from Japan for ₹ 80 million and took four months to instal.

Doing away with cemented pillars, 62 elliptical pylon columns of 20 metres (66 ft) in height surround the stadium, which, from some angles, resemble a spaceship.
