The NBCC is inviting tenders for the remaining six stalled Amrapali projects as tenders have already been floated for 10 stalled projects of the group. The projects have been divided into three categories based on the quantum of work remaining and there are different phases for the completion of project which varies from 12 months to 36 months. It depends on the kind of the project, said Chairman-cum-Managing Director, NBCC, AK Mittal, adding that the tender is being floated to appoint the contractor, which is selected through Quality and Cost Based Selection (QCBS) and will be entitled for the payment. Out of the 41,690 sold units, 8,416 units have been handed over. However, no units have been handed over in the Greater Noida projects and also there is no other stalled housing project which has been taken up by the NBCC for carrying out construction activities, he said.
