Rob and Garland:
The "local contractor on course" is a local earthmover. Some of those costs are for entrance road, etc., but the majority are for work on the golf course, including blasting and, especially, sand capping materials and trucking.
The "golf course contractor" is, indeed, a golf course contractor. My associates have done most or all of the shaping work, that's a big chunk of what's owed to me. But the golf course contractor has installed the sand cap and the drainage and irrigation.
Archaeology: my brother works in Arizona, Garland. But some initial assessment must be done for nearly all sites out west because of the possibility of Native American sites. That business has seen difficult times as a result of the slowdown in development, too, incidentally.
