The urban development department has shown the door to 52 architects empanelled with Patna Municipal Corporation (PMC) for failing to furnish information on approved building maps since 2009.
Legal action against them would also be initiated.
On Tuesday, urban development department secretary S. Siddharth told The Telegraph: "In December 2012, the department had sought details within 15 days about approved maps from the architects since the time of empanelment with the PMC. We did not receive any response, which made them liable for being categorised as defaulters."
The architects had been empanelled with the civic body in 2009.
On December 13, 2012, the department imposed a ban on approval of maps for any multi-storeyed building above 11-metre high till the proposed Bihar Municipal Building Bylaws and Building Codes come into effect.
The department, had also asked all urban local bodies to get details of approved maps from all certified architects that included height of the building, width of the road abutting the building, permissible and used floor-area ratio among others.
The department has already initiated the process of fresh empanelment of architects.
Siddharth said: "I have already moved the files for fresh empanelment and the process is expected to start within a week or two. However, the defaulting architects would not be eligible for fresh empanelment."
Developers, too, confirmed that no new building maps and plans are being approved by the municipal corporation at present, which may lead to escalation of the real estate price in the future.
"According to the norm imposed by the urban development department on December 13, 2012, no new building above 11 metres or G+4 is being approved. No building plans and maps are being sanctioned. This would create a gap in supply against demand in the realty sector. Accordingly, prices of new flats and property will witness a surge in the coming days," said Sachin Chandra, the president of Patna chapter of Builders' Association of India.
