The heritage building of 154-year-old Patna Collectorate, spread over an area of 9.6 acres is all set to be demolished for a complete makeover. The process of demolition would begin by the end of next month.

The first new building would house the offices of the registration, transport and excise departments. At present, the transport office is at Biscomaun building and the registration and excise departments are on the Collectorate campus.

"Before we start the construction of the first four-storey building we need to demolish the existing canteen, some small offices and fell trees on the Collectorate premises. We are waiting for the no objection certificate from departments concerned, including forest," Building Construction Board chief engineer (south wing) Gopal Krishna told TOI.

The tender for constructing the building has already been floated. The estimated fund allocated for the first building is around Rs 10 crore. The master plan for the new Collectorate has been designed by a Delhi based firm -- Jaiswal and Jaiswal Consultants.

"We want the construction process to complete fast, so all the buildings would be built in steel structure and precast beams and pillars would be used," said Krishna.

"After the completion of the foundation work, it would take around six months to complete the building," claimed technical secretary to chief engineer, building construction department, Ravinesh Kumar Sinha.

The new hi-tech Collectorate building would have a centralized structure and Patnaites would get rid of the hassle of moving from one place to another to get their work done. The new building would have all the modern features, including parking space, elevator, back-up power, earthquake-resistant and well-defined seating space for the visitors.

The final design of the new Collectorate also has a dedicated green park on the campus. The main Collectorate building would be a five-storied structure with a conference hall.

On the Collectorate premises, there would be five separate buildings which will house several offices -- SDO building, multi-utility facility centre, Treasury District Board and transport, excise and registry (in one building). A park and parking spaces would also be provided.

Officials are not sure about the total time in the completion of the construction of the Collectorate building. "It depends on various factors like tendering process and permissions for demolition of existing building in each phase," said an official.
