CST faced many challenges on the Crystal Dome and Tower in Ankara, Turkey. The 86’/26-meter diameter dome, 47’/14-meter high built with our proprietary dome system. The state-of-the-art panel and gutter interface that was featured in ENR Magazine.

This dome is part of the tower that graces the skyline of Ankara above the new Cankayka shopping mall. The dome is a combination revolving restaurant and disco on a thin and graceful concrete tower 350’/106 meters high. The dome was assembled in place using scaffolding as a tower on the top platform to build from the center of the dome out to the perimeter.
