Friday Construction Photo #3

It's been a damp week and the skies are low. The project continues to move forward as a layer of gravel appears to be complete. They've even filled in that hole from last week's photo. I wonder if this layer is to provide a level of separation for the concrete that will be the floor of the building; a layer that would provide drainage possibly? Or, is it to provide a reliable surface for vehicles on the job site; something they'll dig through from time to time to actually build the building. Or both?

In the far corner, you can see the crane they've brought in and assembled. I'm not sure what the yellow boom vehicle is doing; maybe placing or adjusting the massive counterweight on the back of the cab. I've seen that long brown metal lattice piece attached to the crane; they use that to auger out the dirt for the pilings. I think that the firehose-looking line connected to the top of it delivers cement to the tip so they can fill the hole as they pull out the auger. Quite a handy tool. Maybe next week, it'll be up and operating.
