Two-story exhibits are common at the larger association and consumer shows that book downtown Columbus, but the approval process for a double-deck exhibit is slower than a standard island booth because the structure has to be reviewed for weight, egress, and sightlines before it ever reaches the floor.
This page walks through what changes for a double-deck exhibit specifically in Columbus, rather than repeating generic booth-building advice that ignores the local approval steps.
Double-Deck Exhibits execution priorities
- Submit stamped structural drawings for the double-deck exhibit well ahead of the venue's engineering review deadline
- Confirm upper-deck occupancy limits and the required second means of egress
- Check the assigned hall's ceiling height against the full structure height rather than the lower deck alone
- Plan crane or lift access for the upper deck build during the move-in window
Why a double-deck exhibit needs its own approval track
A double-deck exhibit is treated differently than a single-level island booth because the Greater Columbus Convention Center and its fire marshal review require stamped engineering for the load path, a second point of egress from the upper level, and confirmation that the finished height clears the hall's rigging grid.
Skipping that review, or submitting drawings late, is the most common reason a double-deck exhibit gets held up during move-in while everyone else on the floor is already building.
Hall selection matters more for two-story builds
Not every hall inside the Greater Columbus Convention Center carries the same clear height, and Battelle Grand's ballroom configuration is not built the same way as the main exhibit halls, so a double-deck exhibit needs its finished height checked against the specific hall the show has been assigned, not the building in general.
Shows that also use space at the Ohio Expo Center and State Fairgrounds tend to have more flexible ceiling conditions in buildings like the Celeste Center, but drive-in access and staging lanes there are laid out differently than the downtown dock system.
- Greater Columbus Convention Center: fixed hall ceiling heights, dock-fed move-in
- Battelle Grand: ballroom footprint, general session use
- Ohio Expo Center and State Fairgrounds: taller clear spans in some buildings, drive-in loading
Labor and paperwork specific to two-story structures
Because a double-deck exhibit involves overhead work, upper-deck loads, and often a temporary stair or lift, most of that install falls outside what an exhibitor can self-handle even in a venue like the Greater Columbus Convention Center that otherwise allows hand-carried items without labor.
Building the labor call, the engineering review, and the fire marshal walk-through into the same production schedule keeps a double-deck exhibit from becoming the one booth still under construction after the aisles have opened.
- Submit engineering drawings ahead of the venue's stated review window
- Confirm second-egress requirements for the upper deck
- Schedule the labor call to match the structure's actual build sequence
Storing and reusing a double-deck structure
A double-deck exhibit is expensive enough that most owners plan to reuse it across more than one Columbus show, which means storage between events, and any damage to the stair, railing, or upper deck needs repair before the next engineering review rather than discovered at the next venue's inspection.
Keeping the stamped engineering drawings on file alongside the structure itself saves time at the next Greater Columbus Convention Center booking, since the venue will ask for that documentation again regardless of how many times the double-deck exhibit has already been approved elsewhere.
Questions about Double-Deck Exhibits
Do double-deck exhibits need special approval at the Greater Columbus Convention Center?
Yes. A double-deck exhibit needs stamped structural drawings and a fire marshal review covering upper-deck occupancy and egress before it can be built, which is a longer process than a standard single-level booth.
Can a double-deck exhibit fit in every hall downtown?
Not necessarily. Clear height and rigging grid vary by hall inside the Greater Columbus Convention Center, so the full structure height of a double-deck exhibit should be checked against the assigned hall before the design is finalized.
Is upper-deck labor self-handled in Columbus?
Generally no. Even where the venue allows exhibitors to hand-carry small items without labor, work involving overhead structure, lifts, or upper-deck loads on a double-deck exhibit typically requires the general service contractor.
How does the Ohio Expo Center compare for two-story builds?
Some buildings at the Ohio Expo Center and State Fairgrounds offer taller clear spans and drive-in access, which can suit a double-deck exhibit, but the loading sequence and staging lanes are different from the downtown convention center's dock system.
Does a double-deck exhibit need re-approval for every Columbus show?
Usually yes in some form, since even a previously approved double-deck exhibit typically needs its stamped drawings and inspection sign-off resubmitted for each new show and venue rather than carried over automatically from an earlier approval.
