“Bitumen prices have increased sharply, due to which road projects are affected. The prices are so high that it cannot be managed. So the MCD has revised its prices… We (PWD) are also planning to revise the rates, so that the work is completed before monsoon and the people do not face problems,” said Singh. PWD Minister Parvesh Sahib Singh on Thursday said that in line with the Municipal Corporation of Delhi (MCD), which has recently issued a notification revising the rates of construction materials to adjust the cost escalation for its road projects halted due to bitumen crisis amid the West Asia conflict, the PWD is planning to issue a similar order for its ongoing projects. According to officials, there has been around 30% escalation in cost of projects due to rise in prices of raw materials — mainly bitumen — and this has to be adjusted.  Earlier, one metric tonne of bitumen cost between Rs 40,000 and Rs 50,000, but prices have now risen to Rs 70,000-Rs 80,000 per tonne.…
