Alarm bells have started ringing in the government over recent trend of highway builders quoting huge premiums to bag contracts. Road transport and highways minister CP Joshi has directed his officials to do a risk analysis of such bids and devise a mechanism to secure the completion of projects. Essentially, the minister’s fear is that bidders, in their enthusiasm to grab projects, might be over-estimating the lucrativeness of these projects and if their calculations go awry, the projects could get stalled.
