That's what I'm told. As we go farther north, the soil conditions get a little more moist, so they will likely be required to have a greater amount of excavation to get a good solid roadbed. Unfortunately, where you need the gravel most is where it gets a little bit more scarce. But again, we've priced all that based on the best information we can get.
Bill's point is that almost half the total cost is material we can go out and price tomorrow. You just multiply by the number of pieces you need. I'm not saying that it's going to be that simple. But the people we're working with know and understand what we're trying to achieve and what kind of equipment we're talking about. They are quite capable of pricing it within plus or minus 20%.
