Installation
With any of Geometrica's installation methods, the dome goes up quickly, safely and under budget.
Florida Center-out installation.
Center-out
Constructed around a tower, the dome is assembled one ring at a time. As each progressively larger concentric ring is formed, the tower lifts the structure to accommodate its new height. The dome grows outward and upward, gradually forming the shell.

Lift in Place
Using this method, sections are assembled at ground level and lifted into place with a standard construction crane. As sections are added, the dome takes shape. Cladding can be installed after the shell is assembled, or on individual sections as they’re put in place. This method works well when the dome is to cover a high structure and for longitudinal structures. Most assembly can be done at ground level, and other subcontractors can work simultaneously inside the dome.

Perimeter Self-supporting
With this technique, workers assemble a ring at a time, from the perimeter ring beam up using manlifts and cranes. Successive sections are attached until closure at the apex.
