The first tilt-up concrete building on the historic campus of the University of Virginia is now underway. Needham DBS worked with Nielsen Builders to design an insulated, composite tilt-up panel system for the Ivy Stacks Expansion project, an addition to an existing precast building. The panels are over 45’ tall, and feature the innovative IconX Model 23 composite connector (www.iconxusa.com), with edge-to-edge XPS insulation, in a 4 5/8-2-4 5/8 configuration (11 ¼” overall thickness). This design uses 30% less concrete than the comparable non-composite panel design. The site is extremely tight, with very limited panel casting area and narrow crane path. Panels are scheduled to be tilted in mid-December.
