In the process, he not only helped build up India’s ability to handle complex infrastructure challenges, he was also willing to share his formidable knowledge with anyone who cared. A good portion of the credit for the enviable score of India in 2020 holding the top rank in the World Bank database of countries with the largest number of public-private partnership (PPP) projects, must go to him. Among infrastructure projects, if engineering-procurement-construction can be considered the easiest, the PPP route stands at the other extreme. Yet it is necessary, if a government is serious about building the range of roads, ports and airports, railway line or power projects. It is a tribute to Haldea’s ability to read among these huge numbers of projects that anyone he pointed out as a problem child was sure to end up as one.
