Mumbai: The Slum Rehabilitation Authority (SRA) which for several decades has merely been issuing Letters of Intent and NOCs to private builders for slum redevelopment schemes will now be appointing contractors to construct these buildings.The authority has invited bids for redevelopment of ten stalled slum redevelopment schemes at Andheri West, Antop Hill in Wadala, Goregaon, Jogeshwari Vikhroli Link Road, Vikhroli, Chembur and Deonar. The total slum area is 19 acres and 4740 slum households are to be rehabilitated.The ten slums are part of the 228 stalled slum schemes that have been distributed to various govt agencies such as MMRDA, BMC, MIDC, CIDCO and others. SRA officials said the schemes will be auctioned and the builder offering maximum PAP tenements from the sale component will be awarded the contract. “There is a regular PAP component in every slum rehab scheme. The density of tenements allowed is 650 per hectare. When the number of households is less than 650 then the balance is offered as PAPs.With PAPs from the sale component as well we shall be able to get more PAPs,” said an official.
