Quick project answer
A ceiling interface drawing before track setting-out is the document that connects the architectural intent of a movable wall to the structure above it. If that drawing is incomplete, the setting-out team marks a line that later cannot be supported, routed or parked as drawn. EBUNGE movable wall panels are individually movable, suspended from a top track, cross the opening without a floor track, and park at a planned stacking position. Each of those facts depends on decisions that belong on the ceiling interface drawing, not on a site instruction issued after the track line is already fixed.
Why the Ceiling Interface Drawing Comes Before Setting-Out
Setting-out transfers a drawing into physical marks. It is a commitment. Once the track line is marked, the support zone, the route geometry and the parking position are treated as settled by every trade that follows.
A ceiling interface drawing should therefore show the overhead condition in enough detail that the setting-out team is not guessing. The suitability of each route and parking arrangement depends on the approved layout, circulation, ceiling interfaces and operating sequence. It is a coordination instrument that records what has been agreed and what still requires project-specific confirmation.
What the Drawing Must Fix: A Coordination Checklist
Use the following checklist as a review agenda. Each item should be either resolved on the drawing or explicitly flagged as requiring confirmation before setting-out proceeds.
- Support zone: the location and extent of the structure intended to receive the track, shown in plan and section.
- The exact route, junction arrangement, continuous overhead path and parking position must be confirmed from the coordinated project drawings.
- Parking position: where panels will stack when the opening is clear, and how that position relates to adjacent walls, columns and services.
- The exact overhead route and support arrangement must be confirmed by the responsible project team from coordinated drawings.
- Interface with other trades: lighting, sprinklers, air terminals, access panels and any ceiling-mounted equipment near the route.
- Finish interfaces: how the ceiling, adjacent wall finishes and the partition finish meet at the track line.
Support and Route Decisions That Cannot Be Left to Site
Support zones
The drawing should identify where support is intended, but it should not invent capacity. A drawing that shows a track line without a support zone invites the setting-out team to assume the nearest slab or beam is suitable.
Continuous connected routes
Panels travel along the overhead route. Straight, turning and stacking routes should be reviewed from the layout, and any gap, level change or obstruction should be resolved on the drawing rather than discovered during installation.
Parking, Stacking and the Space Beyond the Opening
Parking style is customized to the customer layout and project requirements, and may support compact stacking when the coordinated design permits it. The ceiling interface drawing should show the planned stacking position and the clear space it occupies. This matters in renovation work, where an existing ceiling may already contain services that limit where panels can park.
The drawing should also show how the parked panels relate to door swings, circulation routes and adjacent finishes. These are layout decisions, not performance claims, and they are easiest to resolve before setting-out.
Finish Interfaces and the Visible Ceiling Line
Confirmed finish options include laminate, melamine, fabric, leather, glass and other approved surfaces. The ceiling interface drawing does not need to specify every finish, but it should record where the partition finish meets the ceiling and adjacent construction.
Visible references can support layout discussion but do not verify hidden construction or performance. Those questions require separate project-specific confirmation.
Evidence Boundaries: What the Drawing Does Not Prove
An approved ceiling interface drawing confirms coordination decisions. It does not confirm structural capacity, acoustic performance, fire performance, durability or dimensional suitability unless those items are separately verified for the project.
This boundary protects every party. The drawing can show a support zone, but the structure still needs engineering review. It can show a route, but the route still needs dimensional confirmation. It can show a parking position, but the stacking arrangement still needs to suit the layout.
A Simple Review Sequence Before Setting-Out
- Issue the current ceiling interface drawing to the setting-out team and the trades that share the ceiling zone.
- Walk the route on the drawing: straight runs, turns and the parking position.
- Check ceiling build-up, recesses and services against the track line.
- Record every open item and hold setting-out until the responsible party confirms it.
- Reissue the drawing after any change and repeat the review where the change affects the route.
Pass-door requirements and project documentation can be discussed with the EBUNGE team as part of this coordination. The goal is not to add paperwork, but to make sure the line marked on site matches a drawing that has already resolved the overhead condition.
Frequently Asked Questions
What is a ceiling interface drawing before track setting-out?
It is a coordination drawing that records the overhead conditions affecting a top-hung movable partition track, including the support zone, route geometry, parking position and ceiling interfaces, before the track line is marked on site.
Does the drawing need to show structural capacity?
The drawing itself does not certify capacity.
Can panels cross a gap in the overhead route?
No. Every proposed movement path requires a continuous connected overhead route. Gaps, level changes and obstructions should be resolved on the drawing before setting-out.
How is the parking position decided?
Parking style is customized to the customer layout and project requirements. The drawing should show the planned stacking position and the clear space it needs, and the layout should be reviewed for adjacent doors, services and circulation.
Does the drawing confirm acoustic performance?
No. Acoustic requirements should be discussed as project-specific performance needs.
When should setting-out be held?
Setting-out should be held while any item on the drawing remains unconfirmed, particularly support, route continuity, parking space and dimensional interfaces.
Conclusion: Fix the Interface, Then Mark the Line
A ceiling interface drawing before track setting-out is most useful when it is treated as a decision record rather than a formality. It should show the support zone, the continuous route, the parking position and the finish interfaces, and it should clearly list what still requires project-specific confirmation.
EBUNGE movable partitions are top-hung and move without a continuous floor running track. That makes the overhead condition the critical coordination surface. Review the drawing with the project team, confirm support, acoustic and dimensional requirements for the specific project, and only then proceed to setting-out.
