The estimated project cost of the new Parliament building may increase by more than Rs 200 crore due to higher expenditure on steel, electronics and other works, and the CPWD is expected to get the Lok Sabha Secretariat's approval for the enhancement, sources said on Thursday.

Earlier this month, the Central Public Works Department (CPWD), the nodal agency for the construction of new parliament building, had sought in-principal approval of the LS Secretariat for the cost enhancement, the sources told PTI. They said that after the enhancement, the project is expected to cost around Rs 1200 crore.
