i have found to check the newspapers for current and past biddings. The past bids, take the time to go and prepare a estimate based on your time, equipment, manpower and experience for a comparision in estimates.
For current bids participate in the ones that will be announcing the bids openy after it has been awarded. You will soon learn how the numbers look. The business knows the numbers were just there, even the one's that are putting out to bid for the first time. They network too.
