Way up on Mt Graham, Arizona there is the Large Binocular Telescope Observatory.

This building experiences some of the most extreme environmental conditions.

To add to the excitement of the extreme environmental conditions, this building won’t hold still.  It rotates 560 degrees and has two roof shutters that open and shut every night for a world class science program.

This summer our challenge was to improve existing metal roofs that have suffered damage due to falling ice and snow.
