RJ you are right - if India is anything like the US on a job that big with bridges, roads, etc... they would not be able to handle the entire job themselves. Our boys probably got the asphalt on the project - and the rest was the other company and other subcontractors. JMHO
I have a friend that works for fred weber industries, they are a large road construction company, but they don't do bridges, the equipment and liablility is too high so they do a joint bid on the contract with the bridge builder acting as a sub contractor. Fred Weber is the genteral etc.....
Hope this helps GO VCTY
