Below are some construction photos.
The structure is next to a mock up. We changed a lot based on the mockup.
The start of the elevated office
Platforms and stairways
Elevated platforms
The one side looked kind of bare so we added a two tier shed and a dust collector
Mock up for the loading shed
The loader it self was painted to look like concrete. The shed / office etc were painted dull nickel. I then lightly sprayed a textured paint call Caribbean Sand to give the effect of accumulated rock dust.
