"By 2040 more than 70 per cent of the population will move to urban areas and that will require investment to the tune of USD 20 trillion to create infrastructure for this population," Singh said at Confederation of Indian Industry (CII) Conference on Infrastructure Project Management here today.
Citing the example of the US which will need nearly USD 3.6 trillion by 2020 to keep the current infrastructure going, he said India will not only have to invest in creating infrastructure but also in developing manpower capability and efficient mechanisms to maintain what has been built.
Singh said the government also faces challenges in executing infrastructure projects particularly the need for a pool of contractors who are supported by a team of skilled personnel who can deliver world class projects.
"We need to develop manpower capability since it is not only important to build correctly at the outset both in respect of design and technology but maintenance is equally critical," he added.

Hiranandani Group co-founder and Managing Director Niranjan Hiranandani said it is very important not to judge timelines by historical data as the scenario has changed from the past view of project management.
"The governments are working faster and more efficiently and the view of project management has moved from taking estimates from engineers to simplifying and solving impediments to make it happen," said Hiranandani.
