Public sector National Buildings Construction Corporation Ltd (NBCC) has identified five to seven cities, covered under smart cities mission, with three different business models for project execution. "Most of the cities are talking to us. Funds are the most important component of smart cities and that's why cities are going for re-development and monetisation of properties. Here we have a big role to play. We are already present in few cities, in States such as Rajasthan and Odisha. New Delhi Municipal Corporation is also talking to us," said Anoop Kumar Mittal, Chairman-cum-Managing Director, NBCC, in an interview to a newspaper. He refused to divulge the names of cities that were on the company's radar. Stating that more clarity would come once special purpose vehicles (SPVs) are in place and requirement of funds is estimated, Mittal said there were three models under which the company can work. "One, we can be a partner in the SPV. Two, we can be project management consultants. Three, we could work on behalf of the municipal corporation and State government to re-develop properties and generate funds for the municipal corporation, which can then use those funds as their equity in the SPV," he added.
