Why Stacking Pocket Drawings Matter in a Contractor Tender
When you prepare a contractor tender for a space that will use movable solid partitions, the term “movable solid partition stacking pocket drawings” often appears in the specification package. These drawings show where panels park when they are not dividing a room. Because EBUNGE movable partition panels are top-hung and move without a continuous floor running track, the stacking pocket must be planned carefully in the ceiling and overhead structure. This article explains what project information is required, how to coordinate these drawings, and which statements need project-specific evidence.
Cost and maintenance requirements depend on the selected configuration, finish and project conditions and require project-specific confirmation. The drawings are not just a detail; they are a coordination tool that links the partition layout, the overhead track route, and the building services. This guide will help you ask the right questions and review the correct documents during tender preparation.
What Are Movable Solid Partition Stacking Pockets?
A stacking pocket is the designated area where movable partition panels are stored when the partition is opened. In EBUNGE systems, panels are individually movable and suspended from a top track. They cross the opening without a floor track, and they park at a planned stacking position. The stacking pocket is that planned position, often a recess or a straight run along a wall where panels gather.
The suitability of each route and parking arrangement depends on the approved layout, circulation, ceiling interfaces and operating sequence. It can be an open stacking area along a wall, or a compact parking zone that is customized to the layout.
Why the Stacking Pocket Is Not a Floor Detail
Because EBUNGE panels are top-hung and do not require a floor track, the stacking pocket is primarily an overhead and ceiling coordination issue. The floor remains clear, which is a major benefit for accessibility and design flexibility. The exact overhead route and support arrangement must be confirmed by the responsible project team from coordinated drawings. This means the stacking pocket drawings must show the ceiling void, the track support points, and any obstructions such as ductwork or lighting.
Which Drawings Specify the Stacking Pocket?
Several types of drawings work together to specify the stacking pocket. No single drawing contains all the information. The project team must review a set of coordinated documents to understand the full requirement.
Partition Layout Plan
The partition layout plan shows the position of the partition when it is extended and when it is stacked. This plan indicates the stacking pocket location, the length of the stack, and the clearance needed for panels to move. It also shows the opening width and the number of panels required. For EBUNGE systems, this plan must be reviewed to confirm that the stacking route is straight or turning as required.
Share the opening dimensions, room layout and intended operating sequence for review.
Reflected Ceiling Plan (RCP)
The stacking pocket must be free of obstructions in the ceiling void. The RCP also shows the track route, which must be continuous and supported. EBUNGE panels require a continuous connected overhead route for movement; the RCP helps verify that the route is clear.
Section Details
Section drawings through the stacking pocket show the vertical relationship between the ceiling, the track, and the panels. They indicate the headroom, the depth of the ceiling void, and the support structure. These details are critical for confirming that the panels can be suspended and stacked without interfering with the building structure.
Track and Support Drawings
These drawings show the track profile, the suspension points, and the connection to the building structure. They are often provided by the partition manufacturer or supplier. For EBUNGE, the track route and stacking positions are reviewed from the layout. The exact route, junction arrangement, continuous overhead path and parking position must be confirmed from the coordinated project drawings.
Stacking Pocket Detail Drawings
These are enlarged details that show the exact dimensions of the pocket, including the depth, width, and any finishes. They may also show how the panels are secured when stacked, though EBUNGE does not specify a particular locking mechanism. The detail must align with the partition layout and the RCP to ensure that the pocket is feasible.
Project Information Required for Stacking Pocket Drawings
To prepare accurate stacking pocket drawings, the project team must provide certain information. This is not just a list of dimensions; it includes functional requirements and site constraints.
Room Layout and Clearances
The layout must show the intended use of the space, including furniture layouts and circulation paths. The stacking pocket must not interfere with these uses. For example, if the pocket is along a wall, there must be enough clearance for the panels to move without hitting furniture or people. The layout also determines whether the stacking route is straight or requires a turn.
Ceiling Void and Structure
The available ceiling void depth is a key constraint. EBUNGE panels are top-hung, so the track and suspension system must fit within the void.
Building Services Coordination
The stacking pocket area must be kept clear of services that would obstruct the panels. This requires early coordination between the partition supplier, the architect, and the MEP engineer.
Finish and Aesthetic Requirements
The finish of the panels and the pocket area must be specified. EBUNGE offers laminate, melamine, fabric, leather, glass, and other approved surfaces. The finish affects the visual appearance and may influence the pocket design, such as the need for a recessed track or a flush ceiling.
Pass-Door and Accessibility Needs
If a pass-door is required within the partition, this must be indicated on the layout and section drawings. The pass-door affects the panel configuration and the stacking sequence. Accessibility requirements, such as clear widths, must also be considered. These are project-specific and must be confirmed with the supplier.
How to Coordinate Stacking Pocket Drawings Without Hidden Performance Claims
Coordination is about ensuring that the drawings are consistent and that the partition system can be installed as designed. It is not about assuming performance characteristics. The following steps help project teams coordinate effectively.
Review the Layout for Straight, Turning, and Stacking Routes
EBUNGE panels can follow straight, turning, and stacking routes, but each route must be reviewed from the layout. The drawings must show the path of the panels from the extended position to the stacking pocket. If there is a turn, the track must be designed to accommodate it.
Confirm the Overhead Route Is Continuous
The overhead track must be continuous from the extended position to the stacking pocket. The drawings must show the track as a continuous line, and the RCP must verify that there are no breaks. If there is a break, the panels cannot move to the stacking position.
Align the Stacking Pocket with the Ceiling Grid
The stacking pocket often aligns with a ceiling grid or a wall. The drawings must show how the pocket integrates with the ceiling. For example, if the ceiling is suspended, the pocket may require a bulkhead or a recess. The section details must show this integration.
Review the ceiling interface, panel route and stacking position together.
Use Project Documentation for All Technical Decisions
Visible references can support layout discussion but do not verify hidden construction or performance.
Common Pitfalls in Stacking Pocket Drawings
Even experienced project teams can make mistakes. Here are common pitfalls to avoid.
Assuming a Floor Track Is Needed
EBUNGE panels do not require a floor track. Some designers may assume that a floor guide is necessary, but this is not the case. The drawings should not include a floor track unless it is for another purpose.
Ignoring the Turning Radius
If the stacking route includes a turn, the track must be designed with an appropriate radius. The drawings must show the turn and the clearance needed for the panels to swing. This is often overlooked in early layouts.
Not Coordinating with MEP Services
Lighting fixtures or ductwork may be located directly above the stacking pocket, obstructing the track. This is a common issue that can be avoided by early coordination. The RCP must be checked for conflicts.
Oversizing or Undersizing the Stacking Pocket
The stacking pocket must be sized correctly to fit the panels. If it is too small, the panels will not fit; if it is too large, it wastes space. The drawings must show the exact dimensions.
Acoustic Considerations in Stacking Pocket Design
They are laboratory measurements that indicate how much sound is reduced. But the actual performance depends on the entire system and the installation.
