About 10 fire tenders reached the spot and doused the fire that started on the first floor of the multi-storey building.

No casualties were reported in the incident, according to police.

The new secretariat named after Dr BR Ambedkar is being constructed in an area spanning about 7 lakh sq ft at a cost of Rs 610 crore.

The cause behind the first is yet to be ascertained.
