There is a real problem going on with the contracting companies, who are mostly disorganized. They tend to grab the project without adequate manpower and cash, then they start giving the work in pieces to several sub contractors on the promise to pay them after two/three weeks, but in actual they would pay them by monthly small installments in the several months.

At least the govt. should issue a notification that sub contractors payment should not go beyond 60/90 days.
