LA's SoFi Stadium sets a new standard
with massive roof and video display

F

eaturing the world's largest cable net roof and the world's largest LED content playback
system, SoFi Stadium, the new home for the NFL's Los Angeles Chargers and Los Angeles
Rams, is " as majestic as it is revolutionary, " according to ESPN's Alden Gonzalez.
FabriTec Structures LLC, Dallas, Texas, was contracted in a design-assist role with
the project consultants in developing a technically and commercially viable cable net
roof structure and ETFE cladding system, as well as overall project budget, schedule and
coordinated logistics plan.
Designed by architecture studio HKS, with assistance from structural engineering firm
Walter P Moore, the stadium is built with an arching steel truss compression ring supporting
a double grid cable net roof covered with translucent ETFE and surrounded with perforated
aluminum panels. The roof is comprised of 302 ETFE panels, including 46 mechanized vents
that allow the heat generated by more than 70,000 spectators to dissipate. The roof consists
of more than 1,400 tons of double orthogonal grid steel and approximately 67,000 tons of
ETFE membrane, secondary steel, gutters, cross clamps, cable struts and retractable vents.
Suspended from the roof of the stadium, the Oculus is a 4K end-to-end video board
spanning 120 yards, weighing 2.2 million pounds and covering 70,000 square feet.
Celina Industries, a division of Celina Tent, of Celina, Ohio, produced 232 panels for Tribal
Scenery Inc. and Facid North America to cover areas of the Oculus frame for aesthetic
purposes. No two panels were the same. Working from 3D models of the Oculus rigid
aluminum frame, Celina's engineering team used MPanel 3D form-finding software to
transform the rigid frame into a tensioned black mesh skin.
The panels, utilizing mesh from Snyder Manufacturing, were made up of 1,160 individual
pieces welded together using hot air welders on 928 seams that averaged 10 feet in length.
The seams all needed to match up with adjacent panels. Celina accomplished this with only
two of the 232 panels getting to the field and needing to be adjusted due to dimensional
form fit and function issues.
